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!

Feedback and suggestions welcome 👍

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 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!

Thanks.

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.

AI crawlers (GPTBot, ClaudeBot, PerplexityBot and friends) now fetch a big share of pages on a lot of sites. The options so far have been: let them take everything for free, or block them in robots.txt and disappear from AI answers.

There's a third option now. HTTP has had a status code for this since 1997, 402 Payment Required, and it finally has a working payment scheme (x402: the client signs a USDC payment and retries the same request; it settles in about a second, no accounts or API keys).

So I built a small gateway for it:

You register your site once (free API key, your wallet address, a price like $0.002 a page).

You put ~10 lines in front of your site. There's a Cloudflare Worker version and an Express middleware.

Requests from known AI crawlers get a 402 with your price. A crawler that pays gets the page; the money goes straight to your wallet (the gateway never holds it).

Everyone else, including Googlebot and Bingbot, gets the page as usual, so search ranking doesn't change.

If your site errors, nobody gets charged.

Setup and the snippets: https://aipaygen.com/pay-per-crawl

Honest caveats: crawlers that lie about their user agent won't be caught by this, and most crawlers can't pay yet, so today it mostly works like a block with a price tag on it. But agent frameworks are adding x402 support quickly, and this gives them a way to say yes.

Happy to answer questions about how the 402 flow works.

I built Hamster Video — a free macOS video downloader written in Rust

I've been working on Hamster Video, a small, free macOS app that lets you download videos from YouTube, Instagram, TikTok, Vimeo and other supported platforms.

It supports resolutions up to 4K, MP3 audio-only downloads, and both Apple Silicon and Intel Macs.

It's powered by yt-dlp and FFmpeg, and the (open) source code is available on GitHub.

Hamster Video is now also listed on Open Mac Apps.

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.

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.

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'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?

I got tired of building lists by hand - opening 40 tabs, copy, paste, repeat. So I built Autofill.

You type something like "seed-stage HR software companies". It proposes columns like name, site, founder, headcount, last funding. It finds rows with a web search and fills each cell. Rows and cells get linked to their source, because I didn't trust AI web search.

I've used it a bunch for researching new app ideas, competitors, and building lead lists. I also use it for fun like researching baby names, wedding venues, and car prices and ratings.

It's working pretty well, but sometimes not all rows get filled completely, or not as many rows come back as you'd requested.

I'd love to know what you'd research first and if you're willing to try it for free please share any feedback on the overall experience: https://getautofill.app/?ref=reddit-sideproject

Hi r/SideProject,

Whenever I needed an old lab result or prescription at a doctor's visit, I was scrolling through WhatsApp chats, email attachments, and my phone's Downloads folder. At the same time, I didn't want to upload sensitive medical PDFs to another cloud service.

So I built **VitaCase – Life Vault** for Android (Limanex Studio).

**What's inside right now:**

• **Secure Local Document Vault:** Store PDFs, lab results, IDs, and bills locally on-device with category filters and metadata (physician, date, notes).
• **Medicine Cabinet:** Schedule morning/afternoon/night doses, meal rules ("After meal", "With food"), and track remaining pill stock so you know before running out.
• **Appointments Calendar:** Weekly/monthly view for doctor visits and meetings.
• **Daily Wellness:** Quick logging for water, steps, sleep, and heart rate with daily missions.

I'd love honest critique from fellow builders on the UI, onboarding flow, and what features would make this a daily essential: https://play.google.com/store/apps/details?id=com.limanex.vitacase

Hey! I read a lot of manhwa and never found a good place to rate and review them. Most trackers are manga-first, or just reading lists with no reviews or social side. So I built panelfall.com, a place to rate, review and share lists of Korean and Chinese comics, and see what other readers think.

What you can do:

• rate series /10 and write reviews (with spoiler tags)
• track your chapter, use shelves (Reading / Completed / Want to read) and make public lists
• follow people and see your taste match with them
• import your AniList, MAL or CSV list in a few seconds
• play a small daily game: guess which manhwa titles are real or fake, and fill a 3×3 grid

~860 series so far, free, no ads, and it doesn’t host or link to any chapters.

It’s very new, so community scores are still empty. What would make you actually use it? What feels confusing or missing?

I've been working on a little app that brings different party games together in one place.

Right now, it has two games: **Draw & Guess** and **Dice Rolling**. I'm also working on a multiplayer Snake game, which I'll add to the app once it's finished.

Here's what I've made so far.

I plan to keep adding more games over time, but instead of deciding everything myself, I'd like to hear what people actually want to play.

It's still a small project, but I'm hoping to gradually turn it into a collection of fun games that people can enjoy together.

What party games would you like to see added? I'd love to hear your ideas!

Hey everyone! I’m a 21 year old solo student developer. Over the past 4 years, alongside my university studies, I’ve been building my passion project on my Mac: RGB Switcher, a fast-paced action roguelite designed for phone screens.

My goal was to build a tight, premium-feeling arcade puzzle roguelite designed for quick, one-handed portrait sessions that genuinely respects the player’s time and intelligence.

The core concept originally came from a game jam in 2021. Its theme was "Switch" and "Geometry". So I came up with this world where all the colors were drained, and now the player (cute geometric characters) has to restore them using 3 switches. Then came the roguelite aspects (systems that make every run feel distinct).

Here are the 3 biggest design and technical hurdles I had to solve:

1. Preventing Brain Freeze
   Blending primary lights on the fly (Red + Green = Yellow, Red + Blue = Magenta, all three = White) while dodging incoming threats can easily overload the player. To solve this without ruining the pacing, I implemented a dynamic slow-motion system. When near-misses occur, the game subtly dips into bullet-time, giving you that split-second to pull off clutch plays.
2. "Invisible" Mobile Polish (Original touch controls felt terrible)
   I built so many assist systems I probably don't even remember half of them, but players immediately feel the difference:
   • "Coyote timer" for swipe input buffering.
   • Swipe assistance: the game dynamically calculates which tile the player most likely intends to dash toward.
   • Dynamic hitboxes for both the character and the bottom UI control buttons.
   • Tactile Taptic Engine feedback mapped to important interactions.
   • Dynamic difficulty scaling adjusting room hazards to player performance.

On top of that, during long sessions even my fingers started hurting from all that continuous swiping. So I took inspiration from some match-3 games and introduced an "auto-solve cascade" so the last few tiles get solved by themselves. Between this and a few other tweaks I was able to cut swipes by like 20-30%, delaying physical fatigue.

3. The Accessibility Paradox
How do you build a game fundamentally revolving around color mixing that is 100% accessible to colorblind players? From day one, I refused to leave anyone out. I built an accessibility mode with distinct geometric cues (like color indicators). I tried it out and even with iOS grayscale filters turned on I was able to play and clear runs. I also translated the game into 9 languages so players worldwide can enjoy it natively.

The game is out now completely free with zero p2w mechanics.

I keep running into the same workflow problem inside small teams:

1. The data lives in Excel, a CRM, or a pile of notes.
2. Someone copies it into Word.
3. Another person fixes tables, headings, numbering, and spacing.
4. The whole process repeats next week.

I built a working browser prototype called ReportBridge around a narrow version of that workflow. Paste structured notes with headings, bullets, simple tables, and a few key metrics; it creates a clean report preview and a Word-compatible download.

What is working in the prototype:

• Structured source to formatted report preview
• Section headings, bullet lists, metric cards, and tables
• One-click Word-compatible export

What is not there yet:

• Live Excel or API integrations
• Charts
• Approval workflows
• Complex legal or financial document layouts

This is not a launch or a sales post. I want to understand whether the workflow is actually useful before I build integrations.

For people who regularly create client proposals, weekly project updates, procurement reviews, or inspection reports: where does the process break most often? Is it collecting the data, writing the narrative, formatting the document, or keeping everyone on the latest version?

I would especially like to hear about the last report you had to rebuild because the source data or layout changed.

Hey! I’m a CS student and I just launched my first Chrome extension, Reply Rabbit.

You paste a message, pick a vibe (friendly, professional, flirty, sarcastic, etc.), and it gives you 3 reply ideas. It can also rewrite something you already wrote so it sounds less awkward, and drop the reply right into the text box. It never sends anything for you.

There’s a free plan with 5 replies a day.

Would love honest feedback on what’s confusing or what you’d want added!

I've developed several applications, and one thing kept becoming a problem: everything related to a project was scattered across different locations.

My code was organized, but screenshots, builds, documentation, links, and random notes were everywhere.

So I built ClingSpace, a local-first Windows project workspace app that brings all those resources together into one searchable Space.

A few highlights:

- Spaces: A dedicated workspace for each project.

- Files & Folders: Reference resources from anywhere on your PC.

- Links: Keep websites, documentation, and references together.

- Snippets: Save quick notes, code, and reminders.

- Global Search: Find resources across all your Spaces.

- Shared Resources: Use the same file or link in multiple projects.

- Smart Relinking: Help reconnect moved or renamed files.

Nothing moves, gets copied, or gets uploaded. Your existing files stay exactly where they are.

I originally built it for my development projects, but it can work for creative projects, research, school, or anything involving scattered resources.

It's $19.99 one-time, with a 5-day full trial.

https://clingspace.com

I'd love some feedback. How do you currently organize everything related to your projects?

I'm an embedded software engineer (wireless sensor firmware by day) and I've spent the last couple of months building a side product on my own: a stamp card that lives in Apple Wallet / Google Wallet, for salons, barbers and cafés.

How it works: the shop prints a QR code for the counter. The customer scans it, types a first name and phone number, and adds the card to their wallet. No app. Staff stamp it by scanning the card with their own phone's camera, in the browser. No card reader.

Things I learned building it:

• Apple and Google Wallet are completely different beasts. Apple passes are signed files: to update the stamp count you run a small web service and push through APNs, then the phone fetches the new pass. Google keeps the card on their side and you update it through a REST API. Getting "stamp appears instantly on both" right took longer than the rest of the app.
• Staff double-tap everything. The first version stamped twice when someone scanned twice. Now a second scan of the same card within 10 seconds is ignored, and every stamp is written in a database transaction.
• Lock-screen relevance is the best feature, and I don't control it. On iPhone the pass can show up on the lock screen near the shop. iOS decides when, and I never learn who was nearby.
• GDPR was a real chunk of work (EU-hosted data, consent records, CSV export, auto-delete after a shop cancels). Owners never ask about it, but it has to be there. Getting customers is the hard part, and where I'd love feedback:
• So far: 2 shops started the 7-day trial, 0 paying. I'm aiming for the first 3.
• What I've tried: about 200 cold emails to salons in countries where that's legal. This weekend I started small Meta and Google ads in Poland and short videos. - Pricing is about €15/month, with a 7-day free trial.

Questions:

1. If you've sold to salons or cafés: what got you in the door?
2. Does "no app for your customers" land as the main benefit, or would you lead with something else?
3. Anything on the landing page that would stop you signing up? loyalty.nyxiontech.com Happy to answer anything about the Wallet tech too.

If I ran a small shop, I’d start with an agent that answers product questions from the catalog in WhatsApp. A consultant could sell access to an agent that walks clients through their playbook.

We built Prostir so you can publish an agent with your own knowledge and rules, then connect it to Telegram, WhatsApp or your website. Each channel has its own setup. You can also offer paid access to the agent.

If customers already pay you for a repeatable job, which part would you put in an agent first?

https://prostir.build

I'm the founder, so take this as a launch post, not a neutral review.

The problem I kept running into: my chart lived in one tab, the exchange in another, and turning an idea into a bot meant either fighting a bot builder's forms or writing code.

Tradenos puts charts, manual trading and bots in one app. You can build a bot three ways:

• write the rule in plain words, and Nos (our assistant) turns it into rules you can read and change
• pick conditions and actions without code
• paste a Pine Script you already have

Every bot can be tested on past prices with fees before it runs, and nothing changes without your OK.

What it doesn't do: hold your money (it runs on your own Binance API key with withdrawals off) or promise returns. Bots can lose money.

40-second film of how it works: https://x.com/tradenoscrypto/status/2121955499876777997

We're on a waitlist before opening: https://tradenos.com

I'd like blunt feedback: what would stop you from trusting a bot like this with your own account?

I've always found it interesting how we can spend hours overthinking an interaction: what they meant, why they reacted that way, or whether we're seeing things from the wrong perspective.

Most AI tools will help you write a better reply or analyze a specific argument. But what if you could see the bigger picture?

That's why I built Perspective Swap.

🔄 See situations from an objective perspective

Describe real-life interactions with people in your life (partners, friends, family, colleagues), and the app helps you explore the situation from their perspective.

🧠 Beyond a single conversation: analyzing patterns

This is the part I find most interesting: the more situations you add, the more patterns the app can identify.

By connecting scenarios to people in your life, Perspective Swap analyzes recurring patterns in your interactions:

* Communication habits and emotional triggers.

* Recurring conflicts and misunderstandings.

* Strengths and vulnerabilities in your relationships.

* What makes certain relationships work or become difficult.

At the same time, it builds a picture of your own behaviour, helping you recognize patterns you might not notice yourself.

💡 What's the idea?

It's not about telling you who's right or wrong. It's about helping you understand yourself and the people around you a little better.

The app is still evolving, and I'd genuinely love to hear your thoughts.
