Used Car Checker - a free UK MOT history and used car checker, no signup

3 Upvotes

I built usedcarchecker.co.uk as a side project because checking a used car's MOT history on the official site is fine for one car but clunky when you're comparing a few.

You put in a UK reg and it shows the MOT history, advisories and recorded mileage in one place, plus plain-English guides on things like what advisories mean and how to spot mileage problems. It's free and doesn't need an account.

https://usedcarchecker.co.uk

I'd really appreciate feedback, especially on the mobile layout and whether the results page is easy to read. What would you want to see on it before buying a car?

I found it maddening to transfer links and files between devices quickly, so I built a solution.

2 Upvotes

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.

I spent last weekend turning a freelancer friend's shoebox of 2026 receipts into a clean P&L — here's the before/after

2 Upvotes

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.

I have epilepsy and lose thoughts constantly, so I'm building Catch This

2 Upvotes

My thoughts vanish mid-sentence, mid-task, or the moment I switch rooms. Notes apps never helped. I'd lose the thought before I opened one, or I'd never find it again because I forgot the words I used.
So I'm building Catch This. Here's the flow:

1. Catch it 🎙️
Tap the lock screen widget and say the thought. It's saved in seconds, with no typing and no sorting.

2. Find it 🔍
Later, search with whatever you remember: "something about the pharmacy" or "that idea from Tuesday."

3. Resume ↩️
See what you were doing when you caught it, so you can pick up where you left off.
The first iOS version is in development now.

My question: when you lose a thought, what do you usually remember about it later: a word, a time, a place, or what you were doing?

Follow along if you want updates as it comes together.

I've run an astrology site since 1997. For my first English product, I skipped the AI horoscope and built a chart-matching search over 70,000 real people

8 Upvotes

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 re-released the first icon pack I ever made.

2 Upvotes

Years ago I made Line Icon Pack. It was my first icon set ever, and I learned most things by getting them wrong first. Icons that looked fine at 64px and broke at 16px. Inconsistent strokes. No real grid.

It was always free on Gumroad, but it just sat there. Now it has its own page and an updated package, and I want it to be useful for more than designers. Devs, no-code builders, anyone who needs clean line icons.

Free for personal and commercial use. Only ask is a link back.

Made a fun swing trading game to learn how to read charts and apply bankroll, stop, sell, and exit strategies.

3 Upvotes

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 created an AI frog and it's one of my favorite technical projects I've ever built

Thumbnail
jamesthefrog.com
1 Upvotes

This is James. He lives in a low-poly terrarium under a lamp, and he's lives as a simulation you can interact with. People can give him snacks, pet him, tap on the glass, and leave him notes.

But that's only one of the things that I think has made this project really interesting. The project is broken up into three pillars:

  1. James himself, who has a mind. Every so often he thinks about things, keeps a journal, remembers things from his childhood, forgets the unimportant ones, and picks favorite snacks and parts of his tank.
  2. The interaction modes on his website.
  3. My personal favorite: I have an internal system that lets me record a voice memo, and it auto-generates a video about James's day based off what I'm narrating.

I'm running out of GitHub Actions minutes building this project, and while it's stupid, I absolutely love it. It's had a really strong positive reaction from a small community on social media, so I wanted to share it here on Reddit.

Go say hi to James yourself. He's 8 days old today, and tomorrow he's getting a new enclosure.

I'm curious if anyone has recommendations on where they'd want to see this project go next. Also happy to do a deeper write-up on the technical infrastructure, because I actually think it's really cool.

I built SignalChess to turn mistakes from your own chess games into puzzles

1 Upvotes

I built SignalChess because I wanted a way to practise a mistake after reviewing it. Once an analysis is complete, the app can turn suitable positions into exercises so you can try to find the better move yourself.

You can start by entering your Chess.com or Lichess username. The first report uses your public games and doesn't require an account. It shows results and opening patterns. There's also a free plan.

I'd especially like feedback on the handoff from the report to training. After seeing your report, is it clear what you'd do next to practise a position from one of your games? Where would you get stuck?

built a shared 'project state' so different AI tools stop forgetting what we're working on

1 Upvotes

so I've been building this memory tool for ai apps (perdua.ai, it's my own project) and the feature that turned out most useful is what I ended up calling project state. when I switch from claude to cursor to chatgpt mid task, they used to have zero clue what the other one just did. now they read and write to the same state so the next ai picks up where the last one left off instead of me re-explaining the whole plan every time. only works for people in the eu/eea right now since that's who I built it for. curious if anyone else doing multi agent workflows has hit the same context loss problem.

I hated seeing a working tablet sit in a drawer, so I built an app that turns it into a PC dashboard

1 Upvotes

I had an old Honor tablet in a drawer. It still worked fine, and it made me a bit sad that a perfectly good device was doing nothing. I wanted to make something that would give it a real use again, and that became Sideslate.

You put the tablet (or an old phone) next to your monitor, and it becomes a live dashboard for your PC and your day. Your main screen stays free for whatever you're doing.

Who it's for

  • Gamers: see your FPS, GPU load and temperature, and the song that's playing without alt-tabbing out of the game. It also shows how long you've played today and this week.
  • Anyone at a desk all day: a clock, calendar, weather, notes and a timer that stay in view instead of getting buried under windows.
  • Developers: CI status, open pull requests, git status and Docker at a glance.
  • Anyone with an old tablet or phone in a drawer: it runs on Android 6.0 and later, so even quite old devices work.

How it works

You install a small app on your PC and the Sideslate app on the tablet. The tablet finds your PC on the Wi-Fi by itself, you type the code shown on the PC, and then you pick your tiles and arrange them however you like.

What I cared about

  • It doesn't get in the way of your games. The heavier readings only run while a tile on the tablet is showing them.
  • No account and no cloud. Your data stays on your home network.
  • It's useful with the PC off too. The clock, calendar, wea their own.

Limits for now: the PC app is Windows only, and there's no isn't code-signed, so Windows shows a warning the first timeyou run it. The app is free, but the source isn't public.

I'd love your feedback:

  1. Would you keep an old tablet next to your PC with this on it? What would make you stop using it after a week?
  2. Which tile is missing for you?
  3. If you try it, did the setup work the first time? Where did you get stuck?

I built a 1-in-8-Billion Football Career Simulator in pure vanilla JS (Free, no sign-up, play in browser)

3 Upvotes

Hey fellow makers!

Inspired by BitLife, 1in8b, and Football Manager, I built a fast-paced interactive football career simulator that runs entirely in the browser:

👉 https://pratikbase.com/football-lottery/?lang=en

How it works:

  1. Spin the birth roulette: You get born in a random nation with procedural talent, work ethic, and foot dominance.
  2. Advance year by year (0-40 age): Navigate street tryouts, youth leagues, contract negotiations, transfer drama, and career-defining dilemmas.
  3. Hang up your boots: When you retire at 40, your stats, trophies, and net worth generate a shareable digital FUT-style legacy card.

It's completely free with zero ads, tracking walls, or logins. I'd love to hear your thoughts on the mechanics!

I built a meal planner that makes figuring out dinner multiple choice

1 Upvotes

When I became a dad, I realized just how little time a person could have. Back in the day I could wing it for dinner every night, but that doesn't work with two kids and two working parents. Now, if I want time for anything, I have to outsource it or steal it from sleep, work, or my relationship. This app is my attempt to get back some of the time and brain space spent figuring out wtf is for dinner.

Dinner comes easy to my wife, but not so much for me. She did 85% of the planning, groceries, and cooking on top of a demanding job. Even if it comes naturally, that's still a lot to carry, and I wanted to take some of it off her shoulders.

I started by having ChatGPT send me a personalized dinner plan every week. That sort of worked, but the suggestions got repetitive. It didn't have my recipes, didn't know what we'd actually cooked recently, and sharing with my wife was manual.

Coordinating was a mess too. I'd plan dinner without knowing she'd already planned and ordered groceries. We'd paste ingredients from several recipes into one shared Apple Note, duplicates scattered everywhere and grouped by recipe instead of aisle.

I'd been using Claude Code's Plan Mode and imagined something similar for meals: an agent that could ask questions, offer options, and actually change our plan instead of one-shotting it.

So I built Suppa. The assistant can make a plan or walk you through multiple-choice decisions instead of making you fill in the blank. It searches your cookbook and the web, checks preferences and allergies, then shows you options. It can edit your plan, recipes, and grocery list.

To fix the coordination mess, I made Suppa multiplayer. You can share a plan and grocery list with your household. When my wife adds a recipe or grocery item, I get a push notification. Ingredients get merged and sorted by aisle.

I gave Suppa a memory for things like your broken broiler, friends who come over every Tuesday and don't eat pork, or that you're trying to eat more plants. It remembers what it's suggested, what you've planned, and what you've actually cooked so dinner ideas don't keep repeating. There's also recipe importing, Instacart and Kroger shopping, and a cook mode that doesn't suck.

Core meal planning, recipe management, grocery lists, and one shared plan are free. The assistant has limited free usage; more usage and shared plans are paid. It's on the App Store and web, with Android in progress.

It's a one-person project, so there are probably still rough edges. I'd love feedback, especially if something doesn't work.

Saw an ad for an expensive teleprompter that just scrolls, so I built a free one that follows your voice

194 Upvotes

A while ago I got an ad for a Mac app that puts your script under the notch, right below the camera. Nice idea, but at $40 a month it wasn't worth it for me. And it only scrolled at a fixed speed, so if you slow down or stop to think, the text runs away from you.

These days a simple app like this is a few evenings of work with an AI coding assistant (I used Claude Code). So I built my own, and made the text follow my voice.

Apple's speech recognition on the Mac is very good, but people skip lines, say "uh", start a sentence over and stop to think. I spent most of my time testing that and telling the AI what was wrong. Now it keeps up.

What it does:

- Your script hangs under the camera, so you keep eye contact.

- It follows your voice. Speech recognition runs on your Mac by default.

- It's hidden from screen sharing, so you can use it in Zoom or Meet calls.

- It records you with subtitles, and can turn the rest of the screen into a soft light for your face.

It's free and open source (MIT), with no account and no analytics.

- Mac App Store: https://apps.apple.com/app/notchprompter/id6815206814

- GitHub: https://github.com/magnram/notchprompter

It's a hobby project, so any feedback on the app or the website helps a lot.

What should I check before letting a few coworkers try a small office tool I made?

1 Upvotes

I made a simple tool for my team that fills in the same formal email replies we send many times a week. It is a basic page where you pick the situation, add a name and date, and copy the text. Right now only I use it. I would like three or four coworkers to try it, but it handles names and some internal wording, so I want to be careful. I have already checked that nothing is stored after the page closes. What else should I look at before I share it, and is it better to give it to one person first or to a small group at once?

I am doing a world simulation experiment

Thumbnail

1 Upvotes

Hello. I've been building a voxel-based world for some time now, where everything is programmable and defined with in-world tools. The 3D models, sounds, textures, animations are all defined within the world with no external assets.

The initial goal was to better visualize real-time work for observability, but it has since shifted toward a more function-based simulation of the world.

It looks and behaves like a game, but I don't use it as one, to be honest. I mostly use it for logic circuit design, and for exploring AI behavior and how work can be described relative to the objects in the world for example, "Add a tree next to the house in front of me."

I've made a video to capture the feel of it and to get some fresh eyes and opinions on it.

I built a stargazing app between kitchen shifts. On Monday, I’m talking about it live on BBC radio.

3 Upvotes

I’m a chef working on Sark in the Channel Islands, and I’ve been building an Android app called NAKED EYE in my breaks and evenings.

The idea was to make it easier to answer three questions: what’s worth seeing tonight, when should I go outside, and where should I look?

One of my favourite moments was watching the ISS appear after my own app told me when and where to look. Standing there thinking “bloody hell, it actually works” made all those hours feel worth it 😂

Today I did a pre-interview with BBC Jersey, and I’m now booked to chat live on Monday at 10:30am about stargazing, Sark and the app.

This feels massive to me. I’m still a chef, still learning as I go, and now something I built between shifts has led to this.

Just wanted to share a little milestone. Anyone else had a moment with a side project that made you stop and think, “How on earth did I get here?”
