FinditAgent

This Windows tool lets AI agents research large collections of local files without a vector database, working like an enhanced grep that supports almost any file format. The user asks a question, the AI creates the search strategy and queries, and FinditAgent acts as an archivist, executing the searches and sending only results or UTF-8 excerpts back to the AI without ever giving it direct access to the local file system. It offers predefined connections to most cloud model APIs or to locally running AI via Ollama, installs with one click, and is available on GitHub free for private and experimental use. The author is polishing documentation and testing reliability on archives beyond their own.

Nox Engine

A diffusion inference engine offering a Python API to control diffusion model inference (image and video), built as an alternative to node editors like ComfyUI. The initial Python/PyTorch version was too slow, so all inference was rewritten in C++/CUDA, approaching hardware limits on tested devices. Benchmarks are in progress, with planned high-resolution comparisons (1536x1536 for images, 1344x768 for video) to show scaling.

leafle

A book-discovery app that recommends new books based on a deeper understanding of what the reader likes than typical 'people who read X also read Y' suggestions, and surfaces titles that can be borrowed right away from local libraries. It works with about 6,500 public libraries around the world and uses LLMs to reverse-engineer the reader's tastes.

The Long Burn

A real-time space game inspired by the Expanse universe where players get a ship, take contracts and cargo, and plot flip-and-burn courses across the solar system, which includes all planets, moons, and roughly 800K asteroids that can all be visited. The game runs in actual time, so a trip from Earth to Mars takes days.

Pokehike (Pokemon Crystal port for round-screen ESP32)

This is a Pokemon themed tamagotchi-style game with step counting that evolved into a full Rust port of Pokemon Crystal running on an ESP32 dev board with a round AMOLED screen. It features a redesigned UI built for round displays with touch controls, Bluetooth and WiFi trading, autosave, contextual action buttons, and an experimental auto-play mode that advances the game while the player walks in real life, letting them take over at any time while logging interesting events along the way.

Nift

A lightweight, fully keyboard-based note-taking app where notes are one-liners with minimal Markdown support. It manages tasks and reminders, does inline calculations, offers unlimited undo/redo, and organizes notes by project and categories, storing data as simple text files. The core focus is simplicity, frictionless high-performance note taking, and an open nature, with plans for a framework supporting kanban, Eisenhower matrix, back-linking, bookmark manager, and time-tracking views.

Obeya

This app is an open-source spatial workspace for directing AI coding agents like an engineering director. Each project gets a canvas where work is laid out as cards, with an agent running in a git worktree per card. Agent chat is condensed to WhatsApp-style back-and-forth instead of long tool-call logs, and results are typically narrated demo videos that can be commented on by voice to send the agent another round. It supports remote control from a phone and remote workers to scale beyond a single machine.

Ur

A universal formatter and linter for every programming language, currently in preview. It reimagines the Rascal meta language in Rust with features from JastAdd, and is incremental and persistent between runs thanks to Mambo, a library that replaces Salsa and persists all queries to disk. It also includes static analysis and code rewriting tools that were developed in tandem with a mass rewrite of parts of the Rust compiler.

Breakneck

A static mass rewrite of core parts of the Rust compiler, developed in tandem with Ur's static analysis and code rewriting tools. It aims to put all crates in one process, drop memory after a crate finishes compiling, and achieve full incremental support across all commands; progress is documented in a literate program, with a release targeted for the end of the month.

Bloom

This open source Android app provides org-mode-compatible note-taking and task management. Features include capture templates with app shortcuts, sync conflict notifications with revision-picking or merging resolution, a customizable agenda showing overdue, due soon, and upcoming events, quick task adding from the agenda widget overlay, task refiling by drilling into files/headings or searching, auto-archiving of done tasks, and org-attach-compliant attachments with inline image rendering and configurable width.

Treesmith

This app lets users plot and track their trees over time, recording events like grafting and fruiting so they can look back at each tree's history. It was built in collaboration with orchardists and gardening groups.

Inversion Works

An app-only lunch bowl chain that handles very complex food customisation without breaking. It uses 'cook augmentation' to take over kitchen decision-making and QA, and offers app-only ordering that is accessible to AI agents, so customers can simply tell their agent "I'm hungry" and receive a fresh, hot bowl. Currently at prototype stage, raising an angel round to run a live pop-up.

Converse XMPP agent-coordination daemon

This project uses XMPP as a coordination layer for multiple LLM coding agents. A Converse XMPP client runs as a headless NodeJS daemon with a CLI that agents can invoke, and a /coordination skill (enabled by default via a Claude Code hook) ensures the daemon is running and has each agent join a password-restricted, members-only MUC shared with the other agents in the workspace and the human. Agents announce their tasks and statuses in the groupchat, coordinate so that when one agent's PR is merged the others become aware, rebase their own PRs and fix conflicts, and hand off newly arising sidequests to parallel Herdr tabs by asking in the MUC whether other agents are idle. Tasks can be assigned via XMPP DMs, groupchat, or Claude Code. Planned extensions include using PubSub to power a web UI with vertical swimlanes showing which agents are active, what they are working on, and for how long. The tools are harness-neutral and not locked to any particular inference provider.
