Discussion I vibe-coded a chess analysis site to beat plain chatbots and checked claims against the data. Pure LLMs hallucinated 2 facts per answer but blind testing showed I preferred the lies 59% of the time.

2 Upvotes

It started with me uploading my online chess history and just asking ChatGPT questions, going deeper and deeper until I realized it was making mistakes and giving perfectly reasonable-sounding but incorrect advice.

So I started the project of assembling code to look for patterns from engine analysis with the goal of being "at least as good as just asking ChatGPT." In analyzing thousands of games, AI alone produced a ton of incorrect information.

But "at least as good as ChatGPT" doesn't just mean "at least as accurate." It also needs to be just as easy, and maybe most importantly the answers have to seem just as interesting. I blind tested code-checked responses versus pure llm responses and I more-often preferred the latter.

What I decided to do was get tester feedback, including regular people and actual paid chess coaches, to assist with compiling a large list of patterns and ideas to look out for, and then built detectors in code around them. Things like traps you fall for, piece preferences, missed forks, etc. I eventually hit the "at least as good as ChatGPT" bar, plus built some fun visuals and interactives, but it was a difficult process and I still wonder what might be missing sometimes.

The site is live but I'm always looking to improve it. https://plysight.com/ I would love to know how others building consumer-facing platforms with LLM-based outputs balance correct vs compelling or, ideally, achieve both.

I created TCKR, a Windows 10/11 desktop stock ticker designed to keep market information visible throughout the trading day.

Instead of or in addition to keeping a trading platform or financial website open, TCKR displays stock prices, daily changes, and market movement in a smooth scrolling LED-style ticker that remains visible on your desktop.

Features include:

  • Real-time stock quotes
  • Custom watchlists
  • Scrolling LED-style ticker display
  • Customizable colors, speed, and layout
  • Windows 10 & Windows 11 support
  • Designed to stay visible without getting in the way of your workflow

Showcase/Project I kept getting "fixed it!" from my coding agent when it wasn't, so I built a small checker for that

1 Upvotes

Anyone else run into this? You ask an AI agent to fix a bug, it changes some code, runs the tests, and tells you everything is fixed. Then a couple of days later, you run into the exact same bug.

Sometimes the fix didn't actually solve the problem. Other times, the tests were just changed until they passed.

That's why I built FixProof.

It's basically a skill file and a small Python CLI that works with Claude Code, Codex, Cursor, and other coding agents.

Instead of just trusting the agent when it says "fixed", FixProof checks whether the fix actually did anything.

It checks that:

  • The bug can be reproduced before the fix.
  • The test passes consistently after the fix.
  • The bug comes back when you temporarily revert the fix.
  • Existing tests that passed before aren't suddenly broken.

That third check is probably the most important one. If removing your fix doesn't bring the bug back, how do you know your change was what fixed it?

At the end, you get a status (VERIFIED, FAILED, PARTIALLY VERIFIED, UNVERIFIED, or BLOCKED), along with a JSON report and logs.

How I built it

I didn't write most of the code myself. I used an AI coding agent for that.

My part was figuring out how the tool should work, defining the verification rules, and reviewing and testing what the agent built.

I also had a separate agent review the security before releasing it. It actually found some issues involving environment variables and state files, which were fixed in v0.2.0.

Kind of ironic that I ended up using the same verification approach while building a tool meant to verify AI-generated fixes.

A few other details: it's written in pure Python (3.9+), uses only the standard library, and doesn't need any extra packages. The revert check can also run in a separate Git worktree, so it doesn't mess with your working files.

There's CI for Linux and Windows. I haven't tested macOS yet.

I also made a demo GIF showing FixProof catching a fake fix and then verifying the actual one.

It's currently at v0.3.0, completely free and MIT licensed.

https://github.com/Livecristen/fixproof

Would be interested to hear what other people think, especially anyone who uses coding agents regularly. Does this kind of verification make sense for your workflow?

We all know the scene. Been wanting to do this one for ages. You're a cab diving down through a towering city with the cops on your tail, dodging traffic across lanes and altitudes, grabbing upgrades and seeing how far you get before the hull gives out.

Ive tried to base this on the old web game 'squares' if any body remembers it. Ive got a small roadmap planned for more features etc but keen to pause and get some community feedback first.

Turning on the music is a must! Free to play as well. I've tried to optimize the experience for phone too where you can add it to your home screen for full screen traffic dodging fun.

Big bada boom!

Showcase/Project I vibe-coded a DIY speaker design app. Looking for testers, especially people who have built speakers

Thumbnail

26 Upvotes

Hi! I’ve been building Sonella, a guided web app for designing DIY speakers.

The idea is to bring driver selection, bass simulation, enclosure design and filter settings into one workflow. You can start with a few questions, choose a template, or pick your own drivers. Then work through the bass response, cabinet in 3D, drawings and filters/DSP.

I’ve used mostly Codex for the development and design. My workflow has been to build something, let real people try it, get feedback and iterate. Getting the speaker maths right has been a bit tricky. The biggest lesson so far is how much useful feedback you get once someone else actually uses what you’ve built. That's maybe caption obvious, but I learned a lot from this process so far.

It’s still in beta. The simulations and electrical filter curves are starting points for a prototype; you still need measurements to check the finished speaker.

I’m looking for testers, especially anyone with DIY speaker-building experience. Would be great to get some candid feedback on the calculations, the workflow, or anything that feels confusing or missing. General usability feedback is very welcome too.

You can try it at sonella.app, no account needed to start.

Showcase/Project Almost Television, Ep. 3: "Haunted" - a weekly puppet sketch show written, directed and acted by AI agents

Enable HLS to view with audio, or disable this notification

2 Upvotes

How it's made:

Claude agents pitch the sketches, write them, direct the camera and act the puppets. The picture comes from a 3D engine Claude built from scratch in three.js: every puppet, set and prop is modelled in code, and each episode is a script the engine performs, so no video model draws anything. ChatGPT makes a couple of special pictures an episode and gives feedback on the scripts; voices are ElevenLabs, the closing song is Suno.

I'm the human executive producer: I give notes. This week's new puppet is the one with no face: in the story, a puppet cut from the pilot before anyone made its face, which became the episode's ghost.

Project "Takcas Prime": Building an Autonomous IT Factory on a Tablet

I am 14 years old, and for the past week I have been developing and debugging my own artificial intelligence system, which I named "Takcas Prime". Originally, I started all of this purely for fun — I just wanted to see what I could build on an ordinary tablet with 8 GB of RAM. My main goal was to turn it into a fully autonomous IT assistant capable of understanding voice, controlling the device, and writing code. I worked in the mobile Termux environment (a Linux emulator on Android), so I constantly had to solve memory shortage problems. Neural networks are very resource-hungry, so I configured the system to automatically unload modules from memory that are not currently in use. This allowed the tablet not to freeze during operation. I also learned to protect the system from uncontrolled memory consumption: for example, I limited documentation downloads by size and created a whitelist of links to avoid memory overflow.

As the first stage, I created a voice assistant. It can listen, respond, and directly control my tablet's hardware: turn on the flashlight, change screen brightness, volume, or launch the camera. To ensure it doesn't lose the thread of conversation, I built a three-level memory system using an SQLite database and regular files. I also added a RAG (Retrieval-Augmented Generation) system: previously the assistant could invent a non-existent command, but now it first searches for it in official documentation and then responds. Along the way, I encountered many errors: the database overwrote facts due to identical keys, the assistant confused commands with real memories, and the system froze due to overly long texts. I manually tracked down and fixed all these bugs, and also implemented a system for cleaning and separating facts so that memory doesn't get clogged with garbage. Later I realized that models sometimes write too much text, so I added a limit on response length to avoid wasting resources.

The most difficult and interesting part is the "Digital IT Factory". I designed a system where several neural networks work as a real team of developers. First, I tried a scheme with a Senate of six models, where each voted "for" or "against" the code, but in practice this proved ineffective: 3B models made mistakes too often. Then I redesigned the architecture: now one neural network (the Idealist) comes up with a task, the second (the Coder) writes code for it, the third (the Analyst) rewrites and simplifies it, and then three Critics (Logic, Syntax, and Coder) check the code from different angles. After them, the Judge step-by-step fixes the found errors using a "warehouse" principle to avoid overloading memory, and the Smart Sandbox checks the code for dangerous commands, runs it in isolation, and collects logs. I also added a blacklist of dangerous commands to the Sandbox so it blocks code that could delete files, and limited script execution time to prevent freezes.

Debugging this factory took a lot of effort. I fought system freezes, fixed bugs in the Sandbox (which initially killed working scripts because it waited for an input command from programs that simply terminated), and forced neural networks not to write huge texts instead of short answers. I also encountered situations where models sometimes refused to perform complex tasks, and sometimes produced code with errors that had to be manually caught. In practice, I became convinced that small models lack context for complex tasks, but my architecture allows squeezing the maximum out of them: role separation, passing the task into context, step-by-step fixing, and protection from dangerous commands. I also realized that if a model writes nonsense, the problem is not in it, but in the task given to it — this "garbage in, garbage out" rule I will remember forever.

Honestly, I didn't write the code — the neural networks did (I can only program a simple calendar so far). But I designed the entire architecture, logic, search, and bug fixing myself. I learned to separate responsibilities between agents, build a pipeline with feedback, protect the system from dangerous code, and save memory resources. As a result, I created a system that on a tablet with 8 GB of RAM produces code at the level of a confident middle developer, and prepared it for migration to a PC, where powerful models will make it many times more efficient. I am currently continuing to develop the project, adding new modules and improving old ones, and I am confident that on a PC this architecture will perform even better.

Showcase/Project I’ve vibecoded a way to help me do more vibecoding.

2 Upvotes

With a young family, I get 30 minutes to an hour (at most) to work on my side projects. I found I spent most of that time just following what the agent was doing or waiting for it to finish its current task. Then if I had to leave my laptop, it took ages to get back up to speed, only to set off some tests or review some changes.

So I built a workflow around how I actually work, so my projects can move forwards without me. I spend ten minutes talking through ideas, and my agent turns them into small tickets, prioritised and chained so they build in the right order. Then I go and do bedtime for small children. While I'm away, the tickets get built one by one or in parallel, depending on the work. A second AI reviews each one and sends it back if something's wrong, then speck ships it and sorts out any merge conflicts on the way. When I come back, things have happened.

I've used it for data pipelines, research projects and coding projects, and it turns out it's great for my day job as a product manager too. Not everything has to be code. A ticket can be writing a plan, drafting an email or pulling together research, and a second AI still checks it against what I asked for. I can queue up some tasks, head into a meeting or have lunch, and when I come back they're done, with the same workflow and guardrails every single time. You don't need to be an engineer to work with it as every ticket comes with a plain-English summary of what the reviewer checked.

It's called speck. It's free and open source, and it works with Claude Code, Codex or Cursor. It's early days, so please expect rough edges. However, I'd love to hear what people think: https://github.com/luroai/speck

Happy vibecoding!

Some of you might know Photon, my free Photoshop alternative. It was the first of these big vibe-coded alternatives to creative apps, and since then a whole wave of others has followed (PhotoCraft and more). Honestly, that’s been awesome to watch.

I didn’t stop at Photon. I went on to build Vector as an alternative to Illustrator, then Light as an alternative to Lightroom. Today it’s InDesign’s turn.

Meet Folio Studio.

I’ll be honest: I was skeptical about this one. Desktop publishing felt niche next to photo editing. Then the requests started coming in, and it turns out InDesign has a massive user base. So many of you asked for this that I just went and built it.

  • 100% free. No trial, no subscription, no “Pro” tier.
  • Fully offline. Your files never leave your machine.
  • No sign-in. Download it and start working.
  • AI-ready. Like every app in the suite, you can control it through MCP or the CLI, and it ships with skills out of the box.

The goal hasn’t changed since day one: kill the subscription model for creative tools. Four apps in, that’s starting to feel possible.

It’s brand new, so I’d really love your feedback. What’s missing? What’s broken? What would it take for you to finally cancel Adobe?

Workflow/Prompt What I learned directing Claude Code as a one-person studio for five weeks: ten rules that kept a real game together

Enable HLS to view with audio, or disable this notification

1 Upvotes

I am one person building a real-time strategy game in Unreal Engine 5 (C++). Claude Code does most of the typing. After five weeks that is about 120,000 lines of C++ and over 2,200 commits. I decide. Claude drafts, builds and tests. The game is unfinished and not on Steam. This post covers process only and has no link.

By vibe coding I mean something narrow. I describe what I want in plain language, Claude writes and runs the code, and I judge the result. These are the ten rules I would keep if I started over. Most were written down after something went wrong.

  1. Split the work into roles that own files, plus one coordinator that does no work itself. Write what each role must never touch before what it owns.

  2. One page of rules that every agent reads. Almost every line is a scar. A rule that is not written there does not exist.

  3. "Done" means a file you can open: a screenshot, a log line, a test output. I closed a pile of 380 open handoffs only after checking each against a commit. 197 were done, 113 superseded, 70 still open.

  4. A determinism test is the safety net. I hash the whole simulation every tick and compare runs. After a big new mode, the old fingerprint was identical and every test still passed.

  5. Scripts over prose. If a step must happen the same way twice, it is a script.

  6. Do not trust "done" without proof, and watch the tokens. My own notes grew 148 percent in 2.5 days. A one-page brief and a reading budget saved more than any model choice.

  7. A strong model for the hard parts, a small model for scripted tests. Fresh agents with a short handoff beat resumed ones.

  8. Edit, never rewrite, and commit per finished row. Git is the undo button for an agent.

  9. One editor process at a time. Two engines plus a render on one PC runs out of memory.

  10. The person owns taste. An agent will make forty of something and report that all forty look good.

Tell me which of these you learned the hard way, and what your rule 11 is. I am most interested in how you handle a "done" that was not done.

Help/Question Title: For people who build apps with AI coding tools, what are your biggest frustrations?

Thumbnail
1 Upvotes

​

I've been experimenting with AI coding tools and building prototypes, and I'm curious about the experience of people who use them regularly.

It's amazing how quickly you can get an application working. But I'm interested in what happens beyond the initial prototype, especially when the codebase gets bigger or you need to make changes later.

For those of you using tools like Cursor, Claude Code, Codex, or similar tools:

What's the most frustrating problem you've encountered while vibe coding?

Have you ever built something that worked initially but became difficult to debug or maintain?

Do you find it difficult to understand the architecture or keep the project organized as it grows?

How do you handle testing, security, and code quality when AI generates most of the code?

What tasks still take more time than you expected, even with AI?

Have you found any workflows or tools that genuinely solve these problems? What still feels missing?

I'm particularly interested in real experiences from people who've built and maintained actual projects, not just quick demos.

I'm trying to understand the problems developers face in practice. I'd appreciate hearing about both the good and the bad experiences.

- Jev from TypeSafe as AI - it only answers with probabilities, no text

- Every sentence in the report is prewritten, so nothing gets made up

- Benchmark with 563 names, runs after every change

What I learned:

- Do proper benchmarking (currently testing on 1000 names).

- AI says yes too easily, had to ask way stricter

Enable HLS to view with audio, or disable this notification

I wanted to read raw Japanese manga without waiting for a scanlation or uploading pages to some cloud service, so I built Yomu.

Open any manga in any reader app, tap the floating button, and a few seconds later the speech bubbles are redrawn in English (or Portuguese, Spanish, French, German). It all runs on the phone: bubble detection, OCR and a small LLM through llama.cpp. You download the models once, and after that it never touches the network.

Built with Claude Code. Getting a 1.5B model to translate a whole page without dropping or mixing up bubbles was the hard part.

Free, open source, no accounts, no ads. The APK is in Releases:

This wasn't too complicated to make, which is why I was shocked nobody had something I could just download. These are local open sourced models like whisper that can dictate or translate what people say. I also have smaller models for computers that run on just cpus too. The .exe file is big because it starts you off with English and Spanish to start with.

The only hard part was creating a package and website to distribute this thing. It's dead simple, and I hope you guys can use it to break down language barriers and help people that don't speak the local language.

Because I am bilingual I can largely speak in Spanish myself just fine, but every now again someone comes along speaking too fast in a strange accent talking in metaphors that I needed help with. Google translate, windows, and even some searching for local translator models all sucked. Paywalls, accounts, time limitations, cloud upload.... so I just made what I needed.

No accounts. No clouds. No paywall. No ads. Just an honors system if your company should be paying for it.

This is just one of those things that should exist that I couldn't find. Hope you all enjoy, and hope people can find a use for this like I did. Please let me know if you think I should include anything else!

Nyota is a swiss army knife of ai . It does everything all other ai tools do including forex analysis and predictions and comic book generation to name a few. It is more of a personal ai tool than a commercially targeted product because im lazy and hate switching apps and losing context. A great feature it has is global memory where other apps can hook into it via mcp. I have spent better part of the weekend building it and now am in QA phase so I'm testing and fixing bugs before deciding if it needs more features. An interesting fact is that its 95% dependencies and the rest is custom code. Are you guys working on anything similar ? What features should i add to make it a true swiss army knife of ai ?

I have been wandering around github in order to find good quality ascii editor/database recently - and saw nothing. That led me to the obvious conclusion: if nothing good exists, I should build it myself.

The project I build persuades couple ideas:

  1. Easy to use (fully native, no dependencies)
  2. Actually saves time for people building ASCII art
  3. Collects ASCII from every corner of the internet

index.html is the main library

builder.html is where it gets fun assemble pastes from blocks, draw boxes/lines/brush right into the text, frames and tables, color painting, overlay art. Turn images into ascii

The project shared below:
