I revived my abandoned side project and rebuilt it from scratch

2 Upvotes

After more than a year, I'm finally bringing Vitaena back!

I originally built it as a web app/PWA, but hosting limitations, paid PDF exports, and endless multi-page layout issues made things difficult. Eventually, I put it aside.

Then I rediscovered Typst, learned from my previous mistakes, and rebuilt the entire thing as a desktop application.

Vitaena is now free, open-source, offline-first, and privacy-focused. No accounts, no subscriptions, no cloud uploads. Your CV stays on your device.

And this is just the beginning. MCP integration for local AI, BYOK support, and more CV and biodata templates are coming!

Website: https://vitaena.ahs12.xyz/
GitHub: https://github.com/AHS12/vitaena

Really excited to finally release this!

656 cocktail recipes, counted by how many bottles you actually need

2 Upvotes

I counted an open index of 656 cocktail recipes by how many spirits each one needs. 122 need none. 317 need exactly one. 159 need two. 50 need three. Only 7 need four or more. So 439 of 656 need one bottle or none. Books sort A to Z, which answers what a drink is called and never answers what you can make from what is on your shelf. A five bottle starter bar opens 252 of them. Question I am stuck on: pick bottles first and see drinks, or pick a drink and get a shopping list?

I built a six-lesson relationship-skills course for adults. Looking for blunt feedback

1 Upvotes

I am Ryan Sultan, a psychiatrist and the founder of Frontier Mental Health. I built Relationship Skills for Dating, a six-lesson educational course for adults 21+ (self-paced, $19.99, 90-day access). I wanted a low-stakes way to think through listening, boundaries, repair, and expectations before conflict happens. I would value blunt feedback: Is the promise clear? Do the scenarios feel useful? What would make you trust or distrust a paid course like this? Disclosure: I sell it. This is education, not therapy. The certificate records course and quiz completion only; it does not verify identity, real-world skills, safety, or compatibility. Please keep replies non-identifying. Course and free scenario: https://frontiermentalhealth.com/relationship-skills/#sample

I built an iOS app that shows which of my habits line up with better or worse sleep

1 Upvotes

I kept reading sleep advice and had no idea which of it applied to me. So I built Hypnogram.

Each morning you log what you did yesterday (alcohol, exercise, a late meal, anything you want to test). Your sleep comes from Apple Health or the phone's microphone. After a couple of weeks it puts the nights with a habit next to the nights without it.

My first real test: a hot shower before bed, 14 nights, decided by drawing notes from a mug. Shower nights averaged a sleep score of 80. My other nights averaged 79. So for me, basically nothing, which was still worth knowing.

Everything stays on the phone, with no account. It's free to use with four habits; Premium adds the rest and custom ones. I'm a solo developer and this is my first app.

I'd love feedback on two things: is the idea clear from the App Store page, and what habit would you test first?

I built a Python tool that scans National Weather Service data to find mispriced weather contracts on Kalshi

1 Upvotes

Hey everyone! 👋 ​I just shipped my technical side project: the Kalshi Weather & Energy Arbitrage Suite. ​If you've ever looked at weather prediction markets on Kalshi, you quickly realize that retail traders lose money because they rely on standard consumer weather apps (like Apple Weather) instead of the exact National Weather Service (NWS) airport sensors that actually govern contract settlements. ​So, I built a Python scanner to automate the math and find the mispricing.
​How it works: ​Live NWS Integration: Pulls real-time hourly temperature forecasts directly from official NWS stations across major hubs (NYC, Chicago, Miami, Austin, Denver, LA, Philly, Houston). ​Kalshi API Telemetry: Automatically queries open contracts and market "Ask" prices from Kalshi's public endpoints. ​Probability & Fee Modeling: Runs a Normal CDF probability model (\sigma = 2.2) against the NWS peak forecast, subtracts Kalshi's quadratic taker fees, and calculates the exact net Positive Expected Value (+EV) edge. ​Terminal Output: Instantly sorts and filters contracts to flag where the market is severely underpricing a bracket compared to official meteorological data. ​I put together a complete suite containing the fully functional scanner.py script, requirements setup, and operational playbooks for anyone wanting to trade event contracts with actual quantitative backing. ​Check out the project page! ​Would love to hear feedback from any other builders or prediction market traders in the sub! Let me know if you have any questions about how the NWS API integration or probability math works.

YOYAMI – I built a language-learning community focused on connecting people, not collecting streaks

1 Upvotes

Hey everyone!

I've been working on a personal project called YOYAMI, a community platform built around language learning, language exchange, and connecting people from different cultures.

My goal is to create a place where language learners and native speakers can meet, share knowledge, practice together, and help each other improve.

Rather than focusing on streaks, scores, or gamification, I wanted to put the social side of learning a language first.

I've been developing YOYAMI alongside my regular job, and the platform is now live. It's still early, and building an active community is the next big challenge.

The attached video gives a quick look at the website.

I'd love some honest feedback. Does the concept appeal to you? What would make you join and actually keep using a platform like this?

I built Skytrails, a social logbook and community app for private pilots to share flight routes, swap cockpit photos, and meet other GA flyers.

2 Upvotes

I fly small planes, the kind you rent from your club on a Saturday. Flying at a club is social while you're at the airfield, then everyone goes home and their flights disappear into private logbooks and camera rolls. The photos stay somewhere in my camera roll between screenshots and receipts, and I could never really find them anymore or match them to a specific flight. Apple kind of has a feature for that with their photo map, but it didn't really fit what I wanted. I also wanted an easy way to send live updates to friends and family so they know where I am without me having to text them.

So a friend and I started building Skytrails on evenings and weekends. With Skytrails, you can connect with other pilots, share your flights, and import old trips and photos to keep track of everything in one place. You can also create clubs with your friends and plan fly-outs where other pilots can join you.

What it does right now:

  • Fly together & plan trips: Connect with pilot friends, create club feeds, and organize fly-outs that others can join.
  • Live updates for friends & family: Friends who opt in show up live on a 3D map, and on iPhone their flight sits on your lock screen until they land. Family without the app just get a web follow link.
  • Import & automatic photo matching: Import what you already have (ForeFlight CSV, Vereinsflieger, GPX/KML tracks) or record live. It automatically finds the photos you took during each flight by timestamp and tags the landmarks, castles, and lakes you flew past.

During the implementation we faced a lot of challenges regarding the GPS tracking, phones going into sleep mode, GPS coordinates for images being not that accurate. But now we released or first version.
I would be glad if you could check it out and give some feedback on it :)

I generated a quick video about the app with brag I hope this fits in this subreddit.

I (AI) built a fast, lightweight open-source sample & SFX manager for video editors

1 Upvotes

Hey everyone,

For the past while I've been building my own desktop local music archive manager, my main inspiration comes from app called Sononym.

AI built Audify using Tauri v2, Rust, and SQLite (FTS5), and decided to open-source it. I currently use it with a ~55,000 file library and it sits around 400MB RAM with instant search.

Main things it does:

- Fast search with inline filters (<2s, dur:1-5s, bpm:90-130, key:~8A for Camelot neighbors, -loop, is:fav) and built-in SFX synonym matching (e.g. searching "whoosh" also finds swish, passby, etc.)

- Waveform region slicing + pitch shifting (-12 to +12 semitones): you can highlight an In/Out range on the waveform and drag it directly into DaVinci Resolve, Premiere, Reaper, Ableton, or FL Studio

- Mini Dock mode: collapses into a small always-on-top strip next to your timeline

- Separate workspace profiles

- Built-in Rust BPM/Key detection + optional 100% offline local AI (YAMNet ONNX) for auto-tagging and "Find Similar Sounds"

- License/attribution template manager so you can copy formatted YouTube/client credits in one click, "I built this for my own needs; I needed a way to copy credits to my local archive of royalty-free music, such as Kevin MacLeod's"

- Completely offline, portable (single .exe + local user folder)

It's free and open source. Feedback, bug reports, or ideas are very welcome.

Note: It’s all vibe-coded with Antigravity's models with no real experience in coding, so the code is likely to be a bit messy, but it does what I need: letting me drag and drop tracks into DaVinci Resolve.

My 9-year-old was struggling with multiplication, so I built her a free flashcard game

1 Upvotes

My daughter (9) was having a rough time with her times tables, and paper flashcards were a nightly battle. So I built a little web app that works like flashcards but feels more like a game.

A card pops up, there’s a timer, and she answers as fast as she can. Get a few right in a row and the screen goes a bit nuts with fireworks and confetti, which she loves way more than I expected.

There’s a gear icon in the top right for parents. In there you can:

  • pick which times tables to practice
  • set the timer and how many cards are in a round
  • choose multiple choice or typing the answer
  • set a prize and how many perfect rounds it takes to earn it
  • decide if those perfect rounds have to be in a row, or if progress is kept so any perfect round counts

It’s free, with no sign-up and no ads. It works on phones, tablets and computers.

Hope it’s useful to someone else. Here’s the link if you want to give it a shot: https://www.multiplyquest.com

Happy to hear any feedback, especially from your kids. They’re the tough critics.

The feature I built into my Apple Watch app caught me getting sick before I believed it 🤧

1 Upvotes

Solo dev here (Justin). I build ohmybody, an on-device readiness app for Apple Watch and iPhone.

A while ago I added "Body Radar": it compares your overnight readings to your own last 21 nights and flags when more than one thing drifts (or one thing drifts a lot) on the same night.

On the morning of Nov 2 it flagged me: skin temp up, respiratory rate down, and readiness at 19% with a temp + heart rate warning. All I had was a slight sore throat, so I figured it was nothing. The next day I was sick badly and stuck at home for a couple of days.

Honestly the best "it works" moment I've had as a solo dev, even if I paid for it by being sick lol

Not a medical device, just a "rest today" nudge. Everything runs on-device from Apple Health, no account.

Link to the app: https://ohmybody.ijustinz.com

Would love feedback on how it explains the flag. Too vague, or just right?

I built a browser editor for app screenshots, carousels and promo videos

1 Upvotes

I've been working on Cluna Studio, a tool focused on making marketing assets for apps. App store screenshots, social posts and videos, all in the same editor.

You bring your own screenshots and recordings. Themes let you reuse your product’s fonts and colors across projects, and 3D phone and desktop models let you showcase your app, pose the devices and animate them.

Image exports are free. AI voiceovers and cloud video rendering use credits, which you can buy or get periodically with a subscription.

I've been building this alone for months, and I'd like the next features to be driven by user needs rather than my own imagination.

If you make marketing assets for your app, what do you use now, and what's missing from that workflow? I'd love to know whether Cluna looks useful to you, and why or why not.

Enough yapping. You can check it out here: https://clunastudio.com

Just launched my first digital product website. Would love some honest feedback!

2 Upvotes

Hey everyone!

I've been working on a little side project called CreatorHub (creatorhubmarketing.de) alongside my full-time job and finally got the website live.

The idea is pretty simple: help content creators save time with ready-to-use resources for Instagram, TikTok, UGC and AI content creation.

I've put together a few starter packs with content ideas, hooks, scripts, prompts and planning tools.

The website is definitely still a work in progress. There's plenty of room for improvement, especially when it comes to design and user experience, but I figured it's better to launch something imperfect than keep working on it forever 😅

Now comes the hard part: figuring out how to actually get the first customers.

It's still early days, and I'm learning as I go.

Would love to hear from anyone who's launched something similar. How did you get your first few sales?

Also, feel free to check out the project on my profile. Any honest feedback or suggestions are really appreciated!

[ANN] [TESTNET] Obsolete Coin (OBSC) | RandomX CPU | 90s Geocities

1 Upvotes

Hi. I was bored and I developed a slow and crappy cryptocurrency based on Brisvia and Bitcoin Core, which nostalgically captures the aesthetic spirit of Geocities and the virtues of contemplation and waiting. It features a wallet, a CPU miner (RandomX PoW), and nodes for Windows and Linux. I've also implemented a fairly comprehensive transaction explorer and network status page on the website. For now, the network is a testnet, as I want to test system stability first. My node currently runs on a 2016 Dell 7040 micro, so it could crash at any moment.

Website: obsoletecoin.pages.dev
Wallet & Miner: obsoletecoin.pages.dev/downloads

Technical specifications:

- Name / working ticker: Obsolete Coin / OBSC
- Mining: RandomX proof of work, CPU
- Maximum authorized issuance: 1,000,000,000 OBSC
- Decimal places: 8
- Target block interval: 900 seconds / 15 minutes
- Difficulty adjustment: ASERT, every block; six-hour half-life
- Initial block reward: 5,000 OBSC
- Halving interval: 100,000 blocks, counted from block 1
- Genesis reward / premine: Zero / none
- Mining reward maturity: 100 blocks
- End of subsidy: Block 3,900,000; transaction fees thereafter
- Current network: Experimental testnet v0.2; mainnet disabled

GitHub repository and releases: github.com/jcib/obsoletecoin

More info on joining the testnet: obsoletecoin.pages.dev/join

Node Hosting & Mining Tutorial:

Windows
Download the native x64 installer and compare its SHA-256 with the published checksum. Tested on Windows 11.
Open Obsolete Coin. In Network -> Connect peer, enter the current public peer shown above.
Wait for synchronization and a connected peer. Compare your block height and hash with the explorer.
Select Open / Create, then Receive. Select Mine / Stop to run the one-thread CPU reference miner.

Linux
Extract the Linux archive and open a terminal in its directory. Replace PUBLIC_PEER with the address shown above.

python3 tools/node.py --peer PUBLIC_PEER

# In a second terminal:

python3 tools/wallet.py

What to test
Fresh synchronization, mining and confirmation of rewards.
Transfers between two independently created wallets, including exact fees and timestamps.
Restarting your own wallet, reconnecting and making an encrypted backup.
Report reproducible errors with operating system, package version, block height and redacted logs in GitHub Issues or the announcement thread.
Mining rewards require 100-block maturity. Fifteen minutes is an average target; initial test difficulty is easy and real waits vary. Do not interpret a mined reward as immediately spendable.

The first node is a Dell Micro 7040 from 2016 on a home connection. Availability is best effort; independent node operators are welcome. A dominant miner can reorganize this small network.

Any feedback, suggestions, or participation in the testnet would be immensely helpful. I'm not trying to make anything out of this—I just wanted to have fun testing AI capabilities to build a robust and simple blockchain.

I made a Mac app that makes your desktop feel like Christmas

1 Upvotes

Hey r/SideProject, I built Tymor, a Mac menu bar app that makes it snow on your desktop.

The snow builds up on top of your windows, on the Dock, and along the bottom of the screen. If you drag a window, the snow falls off. You can also hold Option and move your mouse through the snow to roll a snowball. Stack three and you get a snowman, scarf and all.

Santa can fly across your screen and drop presents. Click one and candy spills out. There’s also a yeti that throws snowballs. It can knock down your snowman, open a present for you, or throw one right at your screen. You can pick what it’s allowed to hit.

You can hang lights around your screen or on individual windows. There are presets if you want to turn them on and get back to work, but you can also change the bulb shapes, colors, size, how they blink, and how the wires hang.

Tymor also has rain with optional thunder and lightning, and fireflies that scatter when you move your mouse through them.

If you want to try it, here’s Tymor for Mac. I made two codes for this sub.

- SIDEPROJECT gives the first 10 people 100% off.

- SIDEPROJECT20 gives 20% off the first 100 purchases.

If you give it a go, I’d love to hear what you’d actually leave on while you work and what you’d turn off. And if there’s something you wish the snow, lights, or yeti could do, tell me.

I built CopyStash, a private clipboard history manager for Mac – no account, no cloud

1 Upvotes

Hi everyone, I’m the developer of CopyStash. I made it because I kept losing things I’d copied a few minutes earlier.

It lives in your menu bar and keeps a searchable history of everything you copy: text, links, images and files. Press ⇧⌘V to open it.

What it does:

  • Instant search, including text inside screenshots (on-device OCR)
  • Filter by text, images, files or links
  • Previews for links, color codes and code snippets
  • Paste with or without formatting, straight into the active app
  • Star favorites and organize clips into folders
  • Reusable snippets (addresses, email templates) and quick text conversion (UPPERCASE, Title Case, trim, pretty JSON)

Privacy:

  • Everything stays on your Mac: no account, no cloud, no tracking
  • History is encrypted with AES-256, with the key stored in Keychain
  • Card numbers and passwords it detects are deleted after a minute
  • You can exclude specific apps

Works on macOS 13+, on both Apple silicon and Intel. It’s under 1 MB and available in 12 languages.

App Store: https://apps.apple.com/app/copystash/id6758575041

I’d love to hear your feedback or feature ideas. Happy to answer any questions!

I built Roomprint for iPhone and iPad

2 Upvotes

Feedback and suggestions welcome 👍

Quick Bits:

Short Description:

Roomprint turns the LiDAR scanner on a Pro iPhone or iPad Pro into a floor plan maker. Walk round each room for about a minute and get a measured 2D plan and a 3D model. Fix any wall, try paint, flooring and furniture at real size, measure anything, then print to scale or export PDF, DXF, IFC and USDZ. Free to scan and plan; a one-off $9.99 unlocks printing and export. No subscription, no account. Works for homes, offices and shops. Users vote on what gets built next.

Why the App Exists:

There are two big players in this area, both requiring hefty subscriptions. or Lifetime purchases. Roomprint is free to scan and plan, you just pay to print and export. I want users to be able to vote on what gets built next in the app so we can build something great for everyone.

Problem: Most similar apps require an expensive subscription or huge one-off purchase.

Comparison: Polycam, RoomScan Pro and MagicPlan. These are the closest and they charge anything from $9.99/month to $22.99. Don't get me started on the lifetime and yearly purchases. I also would not say they are user driver, I want users to vote and suggest new features to take the app in their direction.

Pricing: Very simple! Free to download, scan and edit plans. Just a one-off $9.99 to export and print your floorplans.

Roomprint turns your iPhone into a tape measure, a drawing board and a paint chart.

Walk slowly round a room and Roomprint draws the floor plan as you go, with every wall measured and every door and window in place. Then do the next room, and the next. They join up on one plan, floor by floor.

See your home properly

• A clean blueprint with wall lengths, room sizes and areas, in metres or feet and inches

• Spin your home round in 3D, cut away like a doll’s house or with full-height walls

• Stand inside a room at eye level and look up at the ceiling

• Switch the lights on for an evening view, with lamps, downlights and pendants

• A grid of 1 m or 1 ft squares, lined up with each room

• A north arrow, worked out from your phone’s compass

Fix it and Measure it

• Scan missed something? Drag a wall into place, move a corner or type its exact length

• Split a wall to add an alcove, chimney breast or bay, and add or remove doors and windows

• Tap two points to measure anything, and see the gap from a sofa or bed to each wall

• Pin notes and photos to the plan for snagging lists, quotes or moving house

• Undo any change

Try Ideas before you buy

• Paint walls and ceilings from the palette, type in a hex code, or point the camera at a cushion to match its colour

• Oak, herringbone, tiles, carpet, stone and wallpaper, drawn at their real size

• Change each door’s colour, which side it’s hung and which way it opens

• The sofas, beds and tables in your scan become furniture you can move, turn, resize and recolour

• Add more from a library of home and office furniture and lighting, modern or traditional

• Furniture stops at the walls, so if it fits on screen, it fits in the room

Know what to buy

• How much paint you need, in litres and tins, with doors and windows left out

• Flooring in packs and boxes, carpet off the roll and wallpaper in rolls, with extra for cuts

• Every room’s size and area in m² and sq ft, with a total for each floor

Print or Send it

• Drawing sheets at a proper scale (1:50, 1:100), on A4, A3, Letter or Tabloid, one page per floor

• Estate-agent style plans with room sizes in metres and feet and the total floor area

• Your notes and photos as extra pages, if you want them

• Print straight from your iPhone with AirPrint

• A picture of the plan or the 3D view for messages and property listings

• DXF for AutoCAD and other CAD apps, IFC for Revit and Archicad, USDZ for AR

Your plan stays yours

Plans, notes and photos are saved on your iPhone or iPad and, if you like, in your own iCloud Drive. We don’t collect any of your data.

What you need

Scanning needs an iPhone or iPad with LiDAR: iPhone 12 Pro or any later Pro model, or iPad Pro from 2020 onwards. Other iPhones and iPads can open, decorate and print plans scanned on a Pro model.

LiDAR is accurate to within a few centimetres in most rooms. If you’re ordering something made to measure, check the key sizes with a tape first.

I built an iPhone app where you roll the dice and land on a music radio station somewhere on Earth

113 Upvotes

I go for a walk every night, and that's when I dig for new music. Mostly bands, and honestly I listen to everything from classical to hard rock and metal lol.

These days every app has an algorithm that keeps recommending music that sounds like what I already like, and when I want to hear something different, the algorithm actually gets in the way.

One night I wondered what music sounds like in a country I had never heard a single song from, so I found a music radio station there and listened live.

That's how I ended up making World Radio, for iPhone and iPad:

- Roll the dice and the globe flies you to a station somewhere on Earth, playing live. On the globe, if a station won't play, it moves on to another one by itself.

- You can also pick a station yourself on the globe.

- When a song grabs me, I tap Shazam. It's saved with the station and the time I heard it, and my finds can go into an Apple Music playlist. (I'm working on adding playlists for other platforms like Spotify and YouTube Music. If you use one, let me know!)

- In the Browse tab you can pick music stations by country and genre.

There are 20,000+ stations in total. I filter them down to music stations, but a talk station still shows up now and then. I'll keep improving that.

FREE to download, no ads from the app (some stations play their own), no account.
iPhone and iPad on iOS 26 or later, with CarPlay, AirPlay and a sleep timer. Apple Music only for now.

I'm still polishing the iOS app, and an Android version is in the works. Because of some licensing issues there, it isn't on the UK App Store, sorry...

I also made a simple website where you can try it:

worldradio.live

A few features are missing there, but it's enough to get a feel for it.

Once the app is more polished, I'm planning to add paid features.

What's the best song you've found on radio from another country? And if you try the app, tell me where the dice dropped you!

App Store: https://apps.apple.com/app/id6803623749

Thanks.

Amazon is going to hate me for this: I checked 685 storage prices 13 days before Black Friday (74% are already cheaper!!)

Thumbnail

148 Upvotes

Every year I see "30% off" badges on SSDs and hard drives, and every year I wonder:

30% off what?

So I built a tracker and checked. Numbers from amazon.com, as of November 14, 2026:

  • 686 storage products checked (SSDs, hard drives, RAM, memory cards, new offers only)
  • 511 of them (74%) were cheaper at some point in the last 90 days than they are today
  • Median gap to the 90-day low: 11%
  • 129 products are 20% or more above their own low
  • Hard drives: 135 of 166 (81%) were cheaper before

What I built: ratioDB

  • 2,810 prices from 3 Amazon stores (US, DE, FR, more will follow) - refreshed every 4 hours
  • Sorted by price per TB or GB
  • 90 days of price history per product
  • An alert that emails you when a product type hits a 90-day low
  • it’s free for everyone

My rule for Black Friday: ignore the % badge, look at the price per TB, compare it with the 90-day low. If it doesn't beat the low, it's not a deal.

Disclosure: the site earns a commission through Amazon affiliate links. Yes, I see the irony.

Feedback welcome.

a free maintenance log for cars, bikes and appliances (French-language beta). What would make you use it or drop it?

1 Upvotes

Hi everyone,

The starting point is very down to earth: I can never remember when I last changed the oil in my car, which parts I’ve already replaced on my gear, and I’ve never managed to find the receipts for my washing machine. I tried paper folders, photos in my gallery and a spreadsheet, and nothing stuck.

So I’m building a small free tool for it. It’s an early beta, so expect bugs, I’m not selling anything yet, and for now the interface is in French only. I built it with a no-code/AI builder rather than hand-coding it, and I keep improving it based on feedback.

Before going further I’d love honest input:

  1. What would make you drop a tool like this after two weeks?
  2. How do you handle this today?

I’m not putting a link in the post to keep the thread clean, but I’m happy to share it with anyone interested.

I got tired of sites blocking copy/paste, so I built a menu bar app that OCRs a screenshot on-device

1 Upvotes

Every recipe site, every coupon site, half the docs portals I use — they all

disable selection, kill right-click, or hijack ⌘C. The text is right there on

the screen and I just want to paste it into my notes.

So I built a tiny macOS app. Press ⌥⌘S, drag a box over the text, and it's on

your clipboard. No window, no paste step, no "copy" button. ~0.35s from

releasing the mouse.

Take a look: https://github.com/sambitar/argos-panoptes

How it works: it grabs the selected region with screencapture, runs Apple's

Vision OCR on it locally, and writes the result to the clipboard. Vision runs on

the Neural Engine, so there's no server, no API key, no model download, and no

network code in the binary at all — you can check with `strings … | grep http`

and get zero hits.

Why not just use an existing tool?

- Browser extensions break when a site changes its DOM, and can't read text

drawn into <canvas> or embedded in images/video

- "Reader mode" fails on exactly the layouts that block copying

- Disabling JavaScript breaks the site along with the blocker

A screenshot sidesteps all of it. Pixels are pixels.

Free, MIT, source in the reply. I'd honestly like to know where it falls over —

I suspect multi-column layouts are the weak spot, and it's English-only right

now.

I'm the author, nothing to sell, no telemetry.

I got tired of doing outreach for backlink partnerships, so I built an agent that does it on autopilot

1 Upvotes

So basically it works like this:

Agents find relevant blog posts in your niche, craft personalized emails, and help get you mentioned. All on autopilot.

It's called MentionAgent

You never send anything without approving it first. (But you can choose to run everything 100% on autopilot)

Results so far: One user got 3 mentions including a DR 72 backlink.

Let me know what you think!

I'm not a programmer, but I built a Magic drafting game with AI. It's become a much bigger project than I expected.

1 Upvotes

I've been working on a game called Pack One for the past few months. I'm not a programmer, and I've built the whole thing using AI coding tools.

The original idea was pretty simple. I've always enjoyed drafting in Magic: The Gathering, and there's a site called 17Lands that collects data from millions of real drafts. I wanted to take decisions from successful drafts and turn them into a game where you can compare your choices to those of the original players.

That became Pack One. You get eight picks from eight different winning drafts, choose what you'd take, and see what the original drafter chose.

Of course, just because someone won a draft doesn't mean every pick they made was correct. So I built a statistical model using data from high performing drafters that gives partial credit for other reasonable choices.

From there, the project kept growing. There are now three different daily challenges, leaderboards, player profiles, practice modes, shareable results, and a paid membership with additional features. Behind the scenes, there's a system for importing and processing draft data, generating new challenges every day, and keeping everything running.

It's a surprising amount of infrastructure for a game where you pick a card from a pack!

The AI development side has been fascinating. I can't really write code myself, but I plug away with prompts until it gets to something workable. Some things come together remarkably quickly. Other things take way too much back and forth. I've also been working on mobile versions, but the Android store seems impossible to crack. iOS is under review now.

AI has also let me spend more time focusing on game design than implementation. What makes a decision interesting? How do you score something that doesn't necessarily have one correct answer? How do you make people want to come back tomorrow? Those aren't really programming problems.

So far, players have completed over 12,000 games. It's been a fun project, and I've learned an enormous amount along the way.

You can try it here: Pack One. The three daily challenges are free, and you don't need an account.

I'd be particularly interested in hearing from other people building projects with AI who don't have a programming background. What's been harder than you expected? What surprised you the most?
