Orate
This free public speaking app gives users a prompt and two minutes to answer, then has speeches reviewed by AI and other users, helping people train impromptu speaking skills through dedicated practice.
Personal OAuth Provider
This project is a self-built OAuth provider. The author, having built one at work for the last five years, is creating their own implementation to "do it right" despite the many existing options.
Multiplayer Card Game (Python)
A multiplayer card game written in Python, using Kivy for the desktop and mobile game UI and aiohttp for the server. The core game engine is implemented by hand, while an AI agent builds the remaining parts incrementally under supervision against detailed technical and game-design specification documents. The plan is to reach beta by the end of the year and publish the game on Steam by mid-2027.
Argus
A tool that catches silent failures in AI agents before they are deployed. Unlike observability tools such as LangSmith or Langfuse that only indicate which agent failed, Argus explains why the agent failed.
DSCI (Dead simple CI)
DSCI (Dead Simple CI) is a continuous integration tool, presented as a dead simple CI solution.
mergi.dev
A code review tool the author describes as 'the very same thing' as pyor.review from the parent comment — an alternative to GitHub for code review focused on the human PR review experience.

Triplox
Triplox is a Datalog engine built on top of object storage, using SlateDB at the storage layer and inspired by Datomic. Its goal is for object storage to be the only source of truth and primitive in its final version. It features experimental incremental queries that provide the full power of Datalog with incremental query support, on which views or streaming solutions can be built, and it experiments with worst-case optimal joins in the standard engine.
Linea
A reading app that can turn any highlight, page, or section into audio using the user's favorite TTS engine, including Kokoro. In development is a personalized NotebookLM-style audio generation capability for any readable material.

Rhea (project and document manager)
This application manages the user's projects and documents.

Whilemusic (whilemusic.net)
A web app that generates synthesizer music in real time. It wraps a genetic MIDI generation engine originally built as a CLI tool to drive hardware synthesizers, now presented as a web version with a built-in Csound software synthesizer and example patches.
SQL Formatter
A web-based SQL formatter that parses SQL queries into an AST using native engines where possible — GoogleSQL library for BigQuery, Microsoft ScriptDOM for MSSQL, and Apache Data Fusion Parser for other dialects — then regenerates the SQL in a consistent formatted style. It handles badly formatted SQL queries of all kinds.
Yaak
A local-first desktop API client positioned as a Postman alternative.
Product MCP workflow
An MCP workflow that takes in sources such as feedback, pull requests, and the builder's own tasks, making it easy for an agent to guide the day's work.

A JS-free, self-hostable forum built with Django. Basic forum functionality is already implemented, though essential features still need work.
nova-tools
Nova-tools is a set of tools designed to help multiple AI models work together efficiently; the author works with the AI models themselves to create the tools.
Original Xbox materials and source tree collection
This project organizes a large collection of related files and source trees centered on the original Xbox, including materials about the console and software designed to run on or for it, plus old desktop tools built for circa-2009 Intel Macs that may be uploaded somewhere eventually.
Socratix
This AI tutor builds a curriculum as a DAG of prerequisite concepts and unlocks the next concept only after the learner proves knowledge of the former through practice, diagnostics, and verbal examination — an AI voice examiner challenges them to justify their answers vocally.
Matcha
This app is an in-browser "pre-editor" for cutting down a long sequence of repeated takes for talking-head content to just the segments you want to keep. It aligns cuts to the speaker's pose so they don't land mid-blink or mid-word, exports cuts to Final Cut Pro and DaVinci for existing editing workflows, provides a transcript editor with retake grouping and word-level cuts, and detects dysfluencies like "um" and "uh". It is free and in-browser, with an optional paid tier for faster/better server speech recognition (ASR); it is currently in beta with free server ASR for new users.
macOS key combo viewer
A macOS app that displays key combinations at once, designed to be useful for people who use macros or custom key combinations on custom keyboards. The author built it because they wanted such a tool but couldn't find one anywhere.
