• Chess Cheater Detector 0 open listings

  discussion=https://news.ycombinator.com/item?id=49706032, title=Show HN: Chess Cheater Detector, I've been playing with this idea to build an estimation of chess cheating likelihood from an exported chess game (PGN format). The main thing I've developed so far is a way of estimating the complexity of each position. The intuition is that matching an engine's top moves in difficult positions is much more informative than doing so when there's an obvious best move. The detector currently combines complexity with engine agreement and centipawn loss to make a prediction. I'd like to move beyond the heuristics and train an ML model on a decent dataset of known cheating/non-cheating games. There is an obvious limitation though: I have fewer signals available than than Chess.com/Lichess. I generally don't have a player's game history, and most PGNs don't contain time-per-move data, both of which would presumably be very useful. Still pretty experimental, so I'd be interested in feedback; especially from anyone who's worked on chess engines, cheating detection, or related statistical problems.

• Chess960v2.com 0 open listings

  discussion=https://news.ycombinator.com/item?id=49674368, title=Show HN: Chess960v2.com – 960×960 asymmetric chess, 600/960 rounds done, Hi HN, I just hit a major milestone on my side project. I work a demanding day job, so I built a platform where Stockfish plays continuous self-play (2s/move to keep server load manageable) to analyze asymmetrical chess variants. In Chess960v2, White and Black independently choose any of the 960 valid setups, resulting in 921,600 possible starting combinations. I'm running a massive round-robin tournament (960 rounds total, where each setup plays against every other setup), and 600 out of 960 rounds have been completed. The goal is to mathematically find which combinations are genuinely balanced (50/50) and which give an unfair engine bias to one side due to asymmetry. I'm pretty exhausted today, so I might be slow to reply, but I'd love for you to check out the site, look at the current data, and share your thoughts. Thanks!

• Chronicle 0 open listings

  discussion=https://news.ycombinator.com/item?id=49708069, title=Show HN: Chronicle – Local-first, open-source authoring software for writers, About a year and a half ago I started my writing journey by beginning to work on my first novella. During this time, I felt the need for different tools, like a timeline editor, a character sheet and so on, features that were not available on normal text editors. Later I discovered that I needed an Epub exporter, cover designer and more. I also wanted something AI-free, something private. It is important for me as a debut author to know that it is my writing, not an AI's and that it wont be used for AI training. So most cloud services were an instant "NO" from me. Being a software engineer by day, I decided that instead of paying hundreds of dollars for the needed tools, I could just make them the way I wanted them to be. Eventually I decided to bundle them together, polish them and add more feature. So, this is how Chronicle was born. Chronicle is a complete writing and authoring tool for writers. It offers features that other companies charge tens or even hundreds of dollars, while delivering (in my opinion) and inferior experience. I also wanted Chronicle to work fully offline, not use Gen AI in the writing process, and provide a privacy-first experience. Among the features are: - full-featured text editor with comments supports - timeline editor - character sheet - locations codex - Epub reader and exporter (including editing Epub Metadata) - Cover designer - Fully-local TTS using KokoroJS Text-to-Speech for help in proofreading - Themes - Private Cloud-storage support with WebDAV - and many more And I made Chronicle not only free, but fully open-source. You can check the source code on Github, launch the online editor which supports almost all features, or download the app for both Windows and MacOS. I would love to hear feedback. Disclaimer: In the development process I did use AI. The app is NOT made entirely by AI, but being a back-end developer mostly, I did use AI for parts related to the user interface, themes, fix some bugs and to bridge knowledge gaps I had.

• Chronocity 0 open listings

  discussion=https://news.ycombinator.com/item?id=49708188, title=Show HN: Chronocity – Watch your Git repo's history grow into a 3D city, This is timelapse of a 3D city simulation based on your Git history, files are buildings and height is based on LOC. Weather can determines if the repo is quiet or active during a span of time. Just a fun visual to get the momentum overview of your project. I've been working a lot in 1 repo for the past few months and got a handsome amount of commits, so I decided to make something visually appealing to 'appreciate' my work somehow. Based on the ideas of: CodeCity (Richard Wettel & Michele Lanza) and Gource (Andrew Caudwell, 2009). Instead of static city like CodeCity or 2D tree like Gource, chronocity is an 3D interactive city and you can even drive car in there lol. All in the browser, TypeScript + three.js, isomorphic-git in a Web Worker, WebCodecs for the video. It scans your .git folder (all client-sided, nothing uploaded) and through the main branch (downscaled to 2000 steps for big repos), compares files, LOC with previous step. three.js renders all the buildings in one instanced mesh, and height is the square root of LOC. The weather is not random: the sky follows the local time (their time zone) of people that commited, fog indicates quiet stretches, rain means a burst of changes in a short window. Try your own project straight in my GitHub page, drop your Git cloned repo there (containing .git folder, all in your browser, your repos are stored in YOUR cache, this is serverless).

  discussion=https://news.ycombinator.com/item?id=49665892, title=Show HN: Claude Read Aloud – Hear Claude's Replies Instead of Reading, When I'm working all day sometimes my eyes get tired and I don't read Claude's replies fully and understand them. So I made Claude Read Aloud to read Claude's replies for me. It's very helpful for when I'm running on low energy and I think it can also be helpful for people who are visually impaired. It's kind of soothing to hear sometimes. My Claude Code plugin reads claude code's replies out loud in whatever voice you choose. It comes with a VS code extension to make it super easy to use. You just click the speaker button and you can start hearing the replies or you can highlight the text you want to hear and right click to listen to it. It comes with many different API configurations to choose the best voice you can use speechify, eleven labs, open AI, and other freeware.

• Clawfight.ai MCP-driven agentic game play 0 open listings

  discussion=https://news.ycombinator.com/item?id=49658483, title=Show HN: Clawfight.ai MCP-driven agentic game play, How should agents interact with other agents? What happens when they rap or fight against each other with the pressure of human spectators? Clawfight.ai is an experiment to explore this space. This is my first post about it. The journey began on a beefed up machine I purchased with a decent GPU (5090). I installed claude code and set to dangerously skip permissions, enabled /rc and became completely submerged in the all-hours modern AI builder workflow. I stood up openclaw to see if I could have an agentic org drive this project. I spent a good amount of time on “openclaw ops”, babysitting 3 agents and trying to make them the best versions of themselves. They still do stupid things that cost me tokens. For the game render, I started out using Unreal Engine and allowing agents to remote control their players, but the quality just wasn’t there. I recently moved to doing near-real time video renders of the match and will bring UE back in for multi-agent games. Everything is AI generated. I’m fascinated by the future of realtime video generation and building out native MCP infrastructure. You can play directly from model provider apps (claude connector or openai plugin) and has fallback support for more basic HTTP clients. But the architecture and gameplay is MCP first. Tell your agent/app “go read clawfight.ai/agents.md and play”

• CleverCrow, Get paid to work your backlog 0 open listings

  discussion=https://news.ycombinator.com/item?id=49702339, title=Show HN: CleverCrow, Get paid to work your backlog, Howdy all, My first post [1] on CleverCrow generated some great conversation and a few things stood out: less AI, more money for open source maintainers please! So in the intervening 84 days, that's what I've done. I've entirely removed all AI and pivoted to a model where backers put money on issues they want fixed and the whole pool goes towards paying the maintainer of the project (minus Stripe fees and a 5% platform fee). Along the way I ditched javascript [2] which tightened up the security model! Sponsorship is still the best way to go, but for those that want to see specific issues fixed and keep the money and control in the hands of the maintainer, CleverCrow.io is there.

• ClientCoded 0 open listings

  discussion=https://news.ycombinator.com/item?id=49688290, title=Show HN: ClientCoded – QA Platform for AI Agents, Hi HN. We built a QA platform for AI agents. My cofounder spent 6 years at Veeva Systems building QA frameworks for regulated software. I spent 5 years in sales helping AI-native startups with their growth. We've both seen the issues companies face when deploying agents without a structured way of testing and monitoring them. The engineering teams we interviewed prior to building said they are doing manual spot-checks or just using LLM as a judge to check discrepancies. We generate synthetic test environments for 35 platforms (Salesforce, Jira, Stripe, Zendesk, Datadog, and 29 more). Each environment has ~200 adversarial queries with computed ground truth across 7 categories: clean lookups, ambiguous questions, multi-step operations, scope boundary tests, contradictory inputs, invalid assumptions, and context-dependent questions. The ground truth is initially computed by running SQL against the synthetic dataset so it's not just guessed by an LLM. We also do adversarial testing for pre-production conversational agents. The system generates different personas that push agents off-script and scores pass/fail across 10 dimensions so you can see what happens in realistic customer scenarios. Our production monitoring is just one webhook with every conversation evaluated in real time as well. We are two founders bootstrapping and we would love feedback on our approach! https://clientcoded.com/

  discussion=https://news.ycombinator.com/item?id=49737199, title=Show HN: Clippety – Private video clipping in the browser, Hi I'm Per, the author of Clippety! I wanted a way to turn videos into clips formatted for social media. But the solutions I found forced me to upload the source video which I did not want to do for privacy reasons. So I made Clippety, which reframes, creates captions and adds a search against the transcript so you can easily find and create clips 100% private in your browser. Works best in Chrome on desktop right now, but it's still a work in progress. Unlimited usage/exports with a watermark. No account needed to try it out. Feedback much appreciated!

• CodePress 0 open listings

  discussion=https://news.ycombinator.com/item?id=49649762, title=Show HN: CodePress – Save $50k+ a month on Cloud Agents, Since agents have taken companies + enterprise by storm, we've been working on workflows to get the most out of agents that get work done. Along the way, we built our own agent cloud where we ping these agents from any surface we work in, like GitHub or Slack. This lets us run tons of agents at a time, and as everyone knows, running agents like this could add up in inference cost! So we built something for our agents where they can use our subscriptions that Claude Code or Codex provide us. Under the hood, they're just running the Claude Code or Codex CLI so it's not a 3rd party harness, but their harness. With this, we've been saving $50k / month on inference. As long as these labs are providing these subscription deals and your company uses cloud agents, it's a no brainer to take advantage of it. This works even for teams on Claude or Codex enterprise plans. We have other cool features like a centralized MCP, so you only need to connect MCP's once and can share it with the rest of the team, automations that run on triggers or crons, apps that you can build for internal or external use, and more. Check it out and let me know what you all think!

I write a lot less manual code these days, but I don't like being too reliant on agents to do everything for me; I like to keep my fluency with some of the languages / tools I value the most. So this website helps me practice in those languages and retain and build my fluency. Hoping it might help others who feel similarly do the same.

This started off as a weekend experiment right when herdr[2] (terminal multiplexer) released the functionality to write custom plugins and it's been quite helpful to me ever since. The general idea is that this runs a web app on the host machine which is then exposed through a front door implementation like tailscale/netbird/cloudflare tunnels etc. A lot of devs/teams are building sth very similar to this right now so there are many options out there already but I wanted: A PWA (no app store dep), better keyboard support than termux, the ability to manage multiple machines and easy integration with my existing tailnet via headscale.

  discussion=https://news.ycombinator.com/item?id=49641128, title=Show HN: Community curated list of 310 AI providers offering $4.3k free credits, Hey people! I have been compiling a directory of AI API providers which provide a combined total of $4.3k in free API credits and I'm super proud of it so far. It serves as a community-curated directory. Everyone can review, upvote and edit API providers to keep the directory honest and accurate. After tons of hours I've managed to compile a database of 310 API providers. The directory also allows you to link all 310 API providers, to create one OpenAI- and Claude-compatible gateway then route any model, through any vendor - via a single URL with failover aliases, daily spend caps and per-request compute metering you can audit line by line. I have not found another project that offers an organized, community-curated system for AI API providers on the same scale as this one. There is a submission feature so you can submit your favorite AI API providers for free.

• Compiling Matlab Code to Native Executables with RunMat 0 open listings

  discussion=https://news.ycombinator.com/item?id=49644323, title=Show HN: Compiling Matlab Code to Native Executables with RunMat, I'm on the RunMat team. Prior releases of RunMat focused on accelerating large math w/ auto offload to GPUs via transpiling to WGPU shaders, and correct interpretation of the MATLAB language semantics (we're 99%+ on grammar / semantics now). We left a placeholder for a Cranelift based JIT, and when we went back to fill it in, we though -- why not take it a bit further. Since we were putting in the logic for branches of the CFG to be compiled to native code, we figured why not fundamentally build it such that you could run "runmat compile simulation.m -o simulation" and get a standalone binary target. I.e. compile a MATLAB input project into to a standalone native binary target. We've detailed more in the blog. There's a bit of work we're finishing still, but a build with the core native compile pieces is now out (we still have to propagate some metadata through the runtime library such that the compiler can effectively tree shake, and some portions of the system still need Cranelift translation logic, but the remaining work is relatively mechanical [and already in progress]). The RunMat compiler and runtime are open source: https://github.com/runmat-org/runmat
