Open source
- Tidy (Mac app, Rust, TypeScript): A local-first Mac app (built with Tauri) that brings a block editor, daily planner, relational tables and meeting recorder together. Meetings are transcribed on-device with Whisper, and local AI writes checked notes and answers questions across each client's meeting history.
- Ekko (Mac app, Swift, WhisperKit): A macOS menu-bar app that turns speech into text in any app. Transcription runs on-device with Whisper through WhisperKit, in 100 languages, with no account, cloud service or analytics.
- RMB (Desktop app, Rust, TypeScript): A free, open-source desktop app that runs a small business's core loop (customers, catalog, stock, quotes, jobs, invoices and payments) with all data on your own machine. No subscriptions, no cloud, works fully offline.
- NotebookMCP (MCP server, Python): An MCP server that lets Claude Code and Codex ask your NotebookLM notebooks questions and get short, cited answers, without loading your documents into the agent's context.
- GMP MCP (MCP server, TypeScript): A write-capable MCP server that lets Claude Code, Codex and Cursor inspect, report on and manage Google Marketing Platform (Campaign Manager 360, DV360, GA4, Tag Manager and Search Ads 360), with dry runs and allowlists for safety.
- Alogos (JS library, TypeScript): A dependency-free JavaScript library that estimates whether an image is AI-generated from statistics of its luminance gradient field. Fast, interpretable and upfront about its limits.
- Sock Puppet Detector (GitHub App, TypeScript, Postgres): A GitHub App that detects coordinated sock-puppet attacks on repositories by scoring account age, naming patterns, activity and coordinated behaviour, modelled on the XZ backdoor attack.
- Chaptergen (CLI, Python, Ollama): A command-line tool that generates YouTube chapters from video transcripts using LLMs, running local models through Ollama by default with optional cloud providers.
- Gmail Cleaner (Apps Script, Google Sheets): A Google Apps Script tool that analyses a Gmail inbox and cleans it up automatically using rules managed in Google Sheets. Built after one online shopping sign-up flooded my inbox.
- Discord Dropbox (Node library, Node.js): An experimental Node.js library that stores images in Discord channels, built out of curiosity. It's for learning only, since it goes against Discord's terms.
