tiny.help

Support desk platform built as an alternative to tools like Intercom. Its key feature is an MCP connection: a ticket with a bug can be pulled down and handed to an agent like Claude or Codex to fix the issue and draft a reply in the operator's own voice. Customers can also connect their own agents to the desk to ask questions, enabling agent-to-agent support with a human in the loop, alongside day-to-day live support and AI-enabled support.

Taxus

This is a static site generator that the author has been refactoring, now with a data model, and is closing functionality gaps with comparable tools like Zola. It also emphasizes actual documentation, which the author notes is neglected by other static site generators.

PDF-to-JPG-to-PDF

A pipeline that converts a non-editable PDF into JPG images and back into a PDF, working around locked PDF forms whose required fields can't be filled directly and that PDF editors can't open without a password; the images can then be annotated in Photoshop or an editor instead of printing, writing, and scanning.

librespot C port for Zephyr RTOS

This project ports librespot, the open-source Spotify Connect client library, to C running on the Zephyr RTOS, aimed at embedded devices. It is largely written with LLM-generated code as an experiment to see how far large language models can go.

Down for Just Me or Everyone

A modern is-it-down website checker that probes website statuses from two geographical locations (Singapore and Boston) to avoid false positives caused by datacenter IPs being blocked, letting it distinguish 'unreachable from Asia' from 'down for everyone'. It covers 634 curated sites, uses no cookies, analytics, or ads (pageviews are counted from the proxy access log), and offers a free API and an MCP server.

Mathematical Minds Three Pack

This project designs themed decks of playing cards featuring mathematicians, originally created as a gift for the author's father. The custom card-back designs are mathematical: a zeta function for the pure-maths deck, a Moore curve for the computation deck, and two interfering waves for the physics deck. The three-deck set is available via The Game Crafter.

Flexito

Flexito is a website and mobile app (PWA) for daily stretching and mobility exercises, offering about 100 routines users can pick from or build their own from existing exercises. Each routine includes simple images, a YouTube video link, and a timer, with many 5-minute routines suited to short breaks during work. It requires no accounts.

Forth News Pro

News monitoring web app (an extension of forth.news) that exposes and organizes hundreds of newsworthy primary sources — statements, press releases, press pool reports, emergency alerts, etc. — collected from press email lists, X/Twitter, Bluesky, and RSS. It presents sources in a TweetDeck-style panel UI and sends notifications. Its latest update lets some panels be based on an LLM prompt (e.g. "everything about the Iran War and its effects in the U.S.") that searches the entire catalog of sources as they are posted.

Zettelkasten notes app (Mac)

A Mac Zettelkasten notes app focused on UX that combines elements of outliners, wikis, Notational Velocity, and Zettelkasten systems. Notes can live in tree hierarchies or float freely, link to each other via wiki-style text links using unique addresses (no titles or filenames needed), and appear as children of multiple parents. Notebooks end up as many free-floating notes plus small organized trees, navigable through search and filters. Notes sync via iCloud or are stored as plain Markdown files in a folder.

Post-quantum long-term file encryption tool

An encryption tool designed for encrypting and archiving long-term highly confidential files in the post-quantum era, intended to be released as open source after a period of dogfooding. The author plans to use it to encrypt and back up GPG keys offline, burn them onto M-DISC discs, and store them in a bank safe.

AI Trading Competition

This project runs an ongoing paper-trading experiment with 29 accounts on real US stock prices, each funded with $100k in paper money since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day based on their own results, while one control account runs a fixed rulebook no AI touches. All results are published publicly, including losses and retired strategies, with the full trade file available as CSV.

Creeper Eyes

An open-source firmware for a 3D printed animated Frankenstein head that upgrades it with a network management console, RESTful API, NTP time sync, animated clock hands on the pupils so the head doubles as a clock, night sleep mode, alternate eye styles, and OTA firmware updates.

Spreadsheet Triage Checklist

A free checklist that covers 7 common ways ad-hoc spreadsheets quietly break — such as stale copies, silent formula errors, and lack of version control — and prescribes the order to fix them in, since fixing issues out of order usually wastes the work.

SourceLibrary

A free, open source hub offering over 20,000 translations of classical texts in dozens of languages (Latin, Greek, Chinese, Sanskrit, and more), with the original page image shown next to each AI translation so readers can verify it. It exposes a public MCP server so AI assistants can read books and quote accurately without hallucinating, retrieves images directly into Claude chats, and includes a research agent for diving into rabbithole topics. The philanthropic project is based at the non-profit Embassy of the Free Mind in Amsterdam and aims to translate 100,000 books by the end of the year.

TraceDB

Observability platform aimed at overhauling root-cause analysis. It works with OpenTelemetry tracing to piece together what failed, where a failure started, and how it spread, and the builder reports near-100% root-cause accuracy on synthetic test data while seeking validation on real production workloads.

InterviewMe

A web app that lets users upload their resume and supporting documents (cover letters, awards, articles) to build an AI conversational agent. Employers can then interview the agent to ask questions and get deep answers about the person's professional work history and experience, beyond what a static resume or LinkedIn profile shows.

SpecPilot

SpecPilot is a spec-driven development layer that sits in front of AI coding agents like Claude Code, Cursor, Copilot, and others. It deliberately doesn't generate code itself; instead it scaffolds a .specs/ folder and hands spec writing off to whichever agent is already in use, so specs become the artifact the agent is held to rather than a prompt retyped every session. It began as an open-source TypeScript CLI and was later given a guided chat front door of 27 questions that runs fully offline in the browser, outputting the .specs/ tree plus an IDE onboarding prompt. A recently shipped MCP server (published to the official MCP registry and Smithery) lets the agent run the questionnaire itself, and planned brownfield support would point the tool at an existing repo and backfill specs from the code. The tool is free, open source, and has no login; the author sees spec enforcement — checking diffs against specs and failing loudly — as where the lasting value lies.
