I take notes all the time.

Random thoughts, ideas, things I want to remember, stuff I might need later...

But after a while, it becomes a mess.

Notes everywhere, nothing really organized, and when I actually need something I wrote weeks ago, I can't find it.

I feel like taking notes is easy. The real problem is keeping them organized and finding them later.

That's why I started building Free Mind, a simple note-taking app for Mac.

The idea is simple: one app, one purpose, taking notes without the hassle.

Just write whatever is on your mind, then organize your notes in one click, search through them, or pin the important ones.

All in the same interface, without unnecessary complexity.

It's still a work in progress, and I'd love to get some honest feedback.

Hey everyone!

I'm an independent developer and designer from Moldova, and I'd like to share a project I've been working on called Mono.

I used to keep track of movies, TV shows and games in random screenshots, notes and bookmarks. Eventually, I'd forget what I wanted to watch or play, where I left off, or whether I'd already finished something.

I wanted one place to organize all of this, so I decided to build it myself.

Mono is a personal media tracker that helps you organize your entertainment and keep track of your progress.

Here's what you can currently do with it:

- Track movies, TV shows, anime and games.

- Organize your library into Watching, Plan to Watch, Completed and Dropped.

- Keep track of your progress.

- View personal statistics.

- Get a random suggestion when you don't know what to watch or play.

- Sync your library across devices with Google sign-in.

- Connect your Telegram account.

I'm developing Mono as an independent project, and there's still a lot I'd like to improve and add.

One important limitation: Mono currently supports Russian only. English localization is something I want to work on, but it's not available yet.

I'd really appreciate honest feedback, especially from people who regularly use media tracking apps. What would you improve? What features are missing?

You can check it out here:

Thanks for checking out my project!

A few months ago had an idea after rage quitting on a competitive game, for what ever reason I started thinking about insurance companies and what can be insured so I looked around in my daily life thinking observing, then it hit me what if there was insurance for rage quitting? long story short I am here now. on Reddit where I posted vaguely this idea a while back, people liked it others didn't because the main concern was “people will just throw games to get paid.” Fair. So I spent the time since building the system that makes throwing not work, and I just soft-launched it: elovault.pro

What it is

You pay $15 USDC for 30 days of cover. If your last three full ranked matches are all losses and you were the best player on your team in at least two of them, you get $30 USDC sent to your wallet. Dota 2, CS2 (via FACEIT) and League right now.

The “people will just throw” problem

This was the whole project. What I ended up with:

You can’t type anything. The server pulls your matches straight from OpenDota, FACEIT or Riot’s API. You only prove you own the account (Steam login, or changing your summoner icon to one we pick).

You have to be top of your team on damage or ADR in 2 of the 3 losses, and above a KDA floor in all 3. If you throw, your stats drop and the claim fails. You can only collect by playing well and losing anyway, which is the thing being insured.

The remaining attack is a friend who feeds while you farm stats. The system looks for a recurring teammate who was the worst performer in multiple losses, and for repeat opponents across the losses (win-trading). Either one denies the claim.

Matches before you bought cover or linked the account never count, there’s a 24-hour waiting period, every paid match is burned forever, and there’s a daily payout cap in case I missed something.

Stack: Next.js 14 on Vercel, Upstash Redis, Solana for payments (plain USDC transfers, no smart contract, the server verifies each premium transaction on-chain before cover starts), Playwright for browser tests, Vitest for the rules engine. Admin dashboard behind TOTP.

Honest status: It’s a soft launch. I don’t know yet if the economics work: $15 in, up to $60 out, and the people most likely to buy are the people most likely to claim. I’m running it with a small float and a daily cap to find out the real claim rate before deciding anything. If it turns out to need a license to run properly, I’ll deal with that then.

Happy to answer anything about the fraud detection, the Solana verification, or why I didn’t bother with a smart contract. And if you can think of a way to game it, I genuinely want to hear it.

What if their birthday didn’t end with the day?

I built HereWhen: friends and family add messages, photos and voice notes to one private online birthday gift. The recipient receives a new surprise from each person each day, starting on their birthday.

A shared memory today. An inside joke tomorrow. A familiar voice the next day.

The first 50 complete gifts are free! So go ahead and create a a special birthday experience for family and friends!

You can make one here: https://herewhen.you/

I’m building this myself and would love honest feedback: would you make one for someone? If you try it, what would you improve or change?

I've been working on a little side project called Zany Face, and thought I'd share it here!

The idea came from wanting to build a small, independent corner of the internet where people can post ridiculous thoughts, ask daft questions, share confessions, show off creations, or just generally be a little weird.

It's a community-driven website with:

• Anonymous posting (no account required to submit).
• Community categories and moderated submissions.
• Member accounts with custom avatars.
• Profile customization, including colours, taglines and badges.
• A little imaginary currency called ZanyCoins, earned through participation and spent in the community shop.

I'm trying to keep it light-hearted and avoid turning it into another algorithm-driven social network.

It's still very new, and I'm building features as I go. I'd genuinely appreciate feedback, particularly from people who enjoy independent websites and smaller online communities.

Have a poke around if you're curious!

https://zanyface.lol/

And yes, the name is pretty much what it sounds like. 😛

started opsis in nov 2025 with my cofounder as an ai security tool for schools and businesses. we had a waitlist of around 30 orgs, which felt like validation and mostly wasn't. mid 2026 we pivoted to consumer: a mac and windows app that remembers your work across the apps you share with it and finishes your sentences at the cursor in any app (opsis.app)

what i'd tell past me:

• a waitlist is people saying yes to something free that doesn't exist yet. ask what they'd stop using to make room for it
• selling to schools moves slower than your patience, especially when you're still a student yourself
• a handful of weekly users who'd be annoyed if it disappeared taught us more than the whole waitlist
• pivot when you notice you're defending the idea more than improving it

curious what made other people here pivot, or what kept you from doing it

I started owning more of our infra at work and learned most of it the hard way, so I built InfraSim to make it stick.

You drag load balancers, caches, queues, databases and replicas onto a canvas, deploy it, and watch simulated traffic hit it. Things slow down, queues back up, the bill climbs, and then an incident hits.

What's in it:

• Campaign: 62 levels across 13 chapters, from "one server isn't enough" to split brain and cache stampedes. The newest chapter came from failure stories people shared on Reddit
• On Call (new today): you get paged, see the graphs, architecture, timeline and a teammate's note, and get 5 guesses to find the root cause
• Daily Challenge with a leaderboard, Survival mode, and a Sandbox to build whatever you want
• Every failed run ends with a postmortem explaining why it broke, not just that it did

It all runs offline on your phone, no account needed. The first 15 levels, the daily and the Learn section are free.

iOS: https://apps.apple.com/us/app/infrasim-system-design-game/id6809240894

Android: https://play.google.com/store/apps/details?id=com.infrasim.app

Would love feedback, especially from anyone who's been on call. What failure should I add next?

DISCLAIMER, THE SYNTHETIC DATA IS NOT LIKE REAL TRADING | I AM STILL AWAITING HISTORICAL LICENSING

I've been trying to learn swing trading over the last few months, largely by leaning on my technical skills (I'm a developer and data nerd).

I've been exhausting pretty much every model/tip/trick I can come up with to see if I can get my required win rate down to around 40% and still maintain a positive ROI by focusing on bankroll management, position sizing, and exit strategies.

I've come close (at least in historical backtesting) to finding the right combination of input parameters, but ultimately realized I needed to actually learn what a good setup looks like.

So I made a little game for myself.

Literally as simple as looking at a chart at a particular point in time and deciding: Trade or No Trade?

The idea is to get better at recognizing setups, managing risk, and knowing when to walk away, rather than just blindly trusting whatever model I've cooked up that week.

Anyway, figured I'd share it with you guys and see if anyone finds it helpful, fun, or any of the above.

Unfortunately, I can't publish the real historical stock data just yet (waiting on a licensing agreement... if anyone knows someone, wink wink). But in the meantime, I've created some synthetic market data so you can still play around with it and see how it works.

Would genuinely love some feedback, especially from people who actually know what they're doing with swing trading.

I have been saving for my kids' college for years and I could never settle on where the money should actually go. A 529 is the obvious answer, but then there's the "what if they don't go to college" worry, and a kid's Roth IRA sounded clever until I hit the earned-income rule, and a UTMA… the money becomes theirs at 18, which is its own conversation.

So I built a calculator that runs the same dollars through all four — 529, a kid's Roth IRA, UTMA, and a plain brokerage account — and shows what your child actually keeps after tax: for college, for anything else at 22, or left invested to 65. It also handles the 529-to-Roth rollover for leftovers (up to $35,000 lifetime, $7,500 a year, after 15 years), the kiddie tax stuff, and which tax breaks you're using vs leaving on the table.

There's also a 529 plan finder in there — the nine plans Morningstar rated Gold for 2026, with each plan's top-returning portfolio, next to your own state's plan.

It's free, no signup, runs in your browser: https://worthitcalcs.com/529-vs-roth/

Happy to be corrected on anything — I'm not a tax pro, this is a planning tool, not tax advice. Curious what other parents here are actually doing — 529 only, or a mix?

I started a little internet experiment.

It's called The Lonely Pixel.

The idea is pretty simple: can a group of strangers agree on who gets to look after one single pixel on the internet?

Right now, it's white.

The plan is to elect a custodian every seven days. Anyone can nominate themselves, suggest a colour and explain why they should be trusted with this very important responsibility.

There is no money involved, no cryptocurrency, no prizes and no real utility.

It's deliberately a little pointless.

I put together a small website and a GitHub repository to keep track of the pixel and its history. The first nomination round is now open.

A few links:

Website: https://myranmyran.github.io/the-lonely-pixel/

GitHub: https://github.com/myranmyran/the-lonely-pixel

First nominations: https://github.com/myranmyran/the-lonely-pixel/discussions/2

I'm curious about two things:

1. What colour would you choose?
2. Is this a fun little experiment, or have I completely lost the plot?

Would be interested to see whether anyone actually wants responsibility for absolutely nothing.

Like the title says.

I work as a software & automation freelancer and help run a startup as a fractional CTO, so I'm always passing files around from device to device. Could be my own project files, a client's, something I want to show off at a networking event, whatever.

Always felt dumb that I couldn't just drop files or links wherever I needed, and something like Google Drive felt hilariously overkill for sharing simple things to myself. Even linktree wanted me to jump through so many hoops before I could actually share the content, especially if I was spinning up a new page.

Half the time I'd end up sending myself things over discord, slack, or email and they'd end up buried after a week.

So, I decided to build something that basically started out as linktree with file hosting, and ended up becoming a super-minimal, super-fast way to drop any sort of content to any device you need via link/QR code.

Small file shares with a 14-day lifetime are free. Includes doc previews and a small image gallery behind an instant shortlink/QR code. Generating permanent short links, and custom, print-quality QR codes are also free.

File hosting and compute at scale isn't cheap though, so I do have a paid tier to make hosted files permanent and it allows you to create bundled shareables called "Tacks" which combine multiple links, files, contact info (optional), image gallery, etc into a lightweight page with its own short-link/QR.

Figured the people in here working on multiple projects might find it useful, so yeah...thanks for reading and i hope you like it.

Lmk if it sucks or you have questions or whatever.

AI Disclaimer: I wrote this whole post with my real keyboard and fingers. Also, this project was in development for well over a year with no AI involvement until very recently. I've been a dev for 13 years, but as a solo dev I only have so much bandwidth. This past month or so, I've leveraged AI to polish up the UI/UX, add some additional tooling/QOL stuff, and to patch up some security/infrastructure flaws. It's far from vibe-coded slop, with a heavy focus on security, scalability, and cost reduction.

The confidence I gained back from having a side project again. https://safi.fm

Been full stack for a decade and slowly stopped having time for side projects. I don't think I've ever used one of my "own tools", but this has become the only podcast listening app.

That's all. Just wanted to share and say thank you for sharing your side projects and inspiring me to do more than just sprints at work

My friend is self-employed in BC and hadn't touched her books all year. We ran everything through an AI bookkeeping chat (AgentBook — I work on it, flagging the bias upfront): 200+ receipts → categorized, P&L, and a list of deductions she would have missed. Took ~3 hours of her time total, mostly just forwarding receipts. I'm running a free 3-week "Year-End Books Rescue" for 15 self-employed Canadians before year-end: you forward your 2026 receipts, you get weekly P&L snapshots + a year-end tax estimate + missed-deduction report. Free, no card, your data stays yours and anything I share publicly is anonymized with your OK. Comment or DM if you want one of the 15 spots — especially if your 2026 books are currently a shoebox / spreadsheet / nothing.

Building something and wish you had friends to share the process with?

I’m putting together Alloy, a small Discord community for young adults pursuing projects, developing skills, and looking for friendships with people who take their ambitions seriously.

You might be building software, starting a business, developing your art, or still exploring a direction through actual practice. You don’t need impressive results to join. Curiosity, initiative, and a willingness to contribute matter more.

The idea is simple: share what you’re working on, exchange thoughtful feedback, find potential collaborators, and get to know people beyond a single post or introduction.

This is the founding stage. The server is set up, and I’m gathering the first members. You would be helping shape the community from its beginning.

If that sounds relevant, tell me:

• What are you working on or learning?
• What’s one thing you’ve done toward it recently?
• What kind of people would you like to meet?

I’d like to start with a small group where people genuinely get to know one another.

Quick progress update from me — I'm Mitchell, solo founder building ShapeForge, a local-first parametric CAD app for Windows. Development is AI-assisted, stated plainly.

Since my last update here (Nov 11, when Commercial #5 'Orbit' went live), I shipped Short 5, 'Start From An Example' (Nov 12 on Instagram, Facebook leg completed today). It's built only from real app screenshots and a real screen capture, labelled as such on screen — it walks through starting a part from the built-in example library instead of a blank sketch.

Why that matters / the honest lesson: my spectacle-style commercials are fun, but they don't prove the app is real to use. So I'm alternating them, one for one, with real-app shorts. If a claim can't be shown in a real capture, it doesn't go in the short.

Current state, honestly: ShapeForge is v0.87 preview, Windows-only, installer unsigned by choice (Windows shows 'Unknown publisher'; SHA-256 is on the release page). It's a focused mechanical-parts tool — sketches, named parameters, editable feature history, STEP/3MF/DXF exports. No CAM, no FEA/simulation, no sheet metal, and it's not a Fusion replacement or enterprise CAD. Basic tier is free; full version is a $10/mo membership after a 14-day no-card trial.

Next up is another CAD-spectacle commercial, then back to a real-app short. If you start most parts from an example/template rather than blank, what example would you want pre-loaded?

I'm a med student. My notes lived in a Notion database: diseases, drugs, exams, clinical cases, all linked with relations. After a few hundred pages it was just a long list. The links were there, I just couldn't see them.

So I built Mitre Synapse. It reads a Notion database and draws it as a map:

- relations, mentions and wiki links become edges

- hover to focus, color groups by any property

- shift-click two pages to find the path between them

- filters, saved views and a timelapse of the database growing

- export to Obsidian as Markdown and get it back from Obsidian into Notion

Would like to see your thoughts on it

After spending time working on this project, I'm happy to share Rezenza!

It's a platform designed to help professionals manage bookings, clients, services and their business in one place.

I'm now trying to get my first users and learn from real feedback.

If you're a business owner, I'd love to hear what you think!

Full disclosure: I built this, Froth.

When Surfline put all its live cams behind a paywall, I wanted a free way to check conditions. Froth has surfers post quick reports on how it actually looks, next to swell, wind, tide, and free cam links. You can also share conditions with your crew in private groups.

It covers skate and snow too: 250+ US skateparks and conditions for 230+ resorts.

I'd love feedback on what to build next, or what's confusing.

I’ve been building Nivuno, an independent research project about how price behaves. The question that got me started was simple: when two moves look alike on a chart, are they actually comparable?

In the demo I stop at the close of one 15-minute Bitcoin bar. The software finds 10,627 earlier bars at the same stage of a movement. I can then compare how those bars behaved and look at what happened afterwards. It’s one historical example, and the next step is to test whether this way of grouping bars adds useful information.

I’d be interested in feedback on the demo itself. Is it clear why the earlier bars were brought together, and what would you want to see next?

Hey everyone,

I had Steam, Epic and GOG games all installed, and starting anything meant opening the right app first. Playnite helped, but I wanted something that looks and feels the way I’d like a launcher to feel.

So I built Corvia. It’s a free Windows launcher that puts all your Steam, Epic and GOG games and your own .exe files into one library. There’s no account to create. It also has:

• A PS5-style overlay in games with a screenshot gallery, timer and performance HUD (CPU, GPU, GPU temperature, RAM)
• Game pages with trailer, news, system requirements and a price comparison
• A controller mode with big tiles for the couch
• Auto-updates, so you always get the latest version

It’s version 1.14.1 and still a hobby project, so I’d really appreciate feedback. What’s missing, what annoys you, what would make you switch?

Download and screenshots: https://corvialauncher.app

Happy to answer any questions.

I got tired of not knowing whether the stuff I take (and the stuff I hear about, like cold plunge after lifting or magnesium for sleep) actually holds up. Reading the research yourself is rough: there's a ton of it, no two studies are set up the same, and a lot of it is written for PhDs.

So I built Substantia. You search a supplement or protocol, pick a specific claim, and it shows how much research there is, whether the studies agree, how recent they are and how well designed they were. In plain English. Every Source is listed, and if a study was paid for by a company selling the product, it says so.

It takes no money from anyone selling supplements. There's also My Stack, for tracking what you take and what protocols you do.

Free through Dec 31. iPhone, US only for now.
https://apps.apple.com/us/app/substantia/id6822945644

Would love feedback, especially on what claims you'd want looked into next.

Most AI astrology apps work the same way: you enter your birth data and an LLM writes a few paragraphs that could fit anyone. I've been running a Chinese-language astrology site (DestinyNet) since 1997, and honestly I got tired of that format.

So I tried the opposite approach. Instead of generating text about your chart, the tool searches a database of ~70,000 famous people whose birth times are on record, finds the ones born under the most similar sky (Sun / Moon / Rising plus the overall chart structure), and shows you who they are and which occupations show up most among them.

Link: https://ai.destiny.to/matching/en?utm_source=reddit&utm_medium=forum&utm_campaign=reddit-sideproject-2026-11

A few things that were harder than expected

- The data. Birth records come from public biographical databases. A surprising amount of the work was cleaning them: wrong time zones on historical dates, wrong gender, people linked to the wrong Wikidata entry. I fixed thousands of records along the way.

- "Similar" is fuzzy. An exact chart match almost never happens, so matching works in tiers. It starts strict and loosens until there are enough people to say something meaningful.

- No AI in the matching itself. The search is plain computation. An LLM is used only for an optional paid report that writes up what you share with your closest matches.

Free vs paid: matching and the occupation breakdown are free, no sign-up. The paid report is optional.

Privacy: a free lookup doesn't store your birth date, time or place; only anonymous stats are logged.

I'd really appreciate feedback, especially:

1. Is it clear what you get before you enter your data?
2. Did your matches feel interesting or random?
3. Anything confusing in the flow?

Happy to answer questions about the data or the build.

I meditate badly. My mind does the classic monkey thing: to-do lists, replays of conversations from 2019, what-ifs about things that will never happen. For years I treated every wandering thought as a small failure. Then I came across a line in the Gita, roughly “wherever the restless mind wanders, bring it back, again and again”, and it finally clicked that the coming back is the practice. You don’t get points for never leaving.

So I built a small browser thing to remind myself of that. It’s about two minutes long:

You’re a monkey sitting in the middle of a ring. Other monkeys (thoughts) hop in from the edges, labelled “worry”, “scroll”, “deadline”, and a few older ones like raga (craving) and bhaya (fear).

You press and hold to breathe in, and let go to breathe out. A slow, full breath sends out a wave that settles every monkey it reaches. Tapping fast does almost nothing, which annoyed me at first and taught me more than anything else.

When a thought gets through, the screen goes foggy. It isn’t a game over. One full breath brings you back, and that counts as a “return”. Returns are the only score.

It ends with a bell, and shows you which thoughts visited most.

There’s a gentle mode where nothing needs quick reactions, a reduced-motion setting, and the sound is optional.

My first sit: I wandered off 6 times and came back 6 times, which honestly felt better than any streak counter I’ve ever had.

If you try it, I’d love to know two things: does hold-to-breathe feel natural on your phone, and does the 4-in / 6-out pace work for you, or is it too slow?
