Apps

Things you can open and use: local-first tools for learning and thinking, and a couple of worlds to play in.

Tools

Local-first apps that run in your browser and work offline. Your data stays on your devices.

Manabi
A reading-first language-learning app for Chinese, Japanese, Korean, and Hebrew. It trains recognition, pronunciation, listening, context, and recall separately, with spaced repetition and prerecorded native audio. It runs offline in the browser and installs as a PWA.

Kurumi
A local-first, AI-native second brain. Capture notes, links, and meetings, then find them again through wikilinks, backlinks, a graph view, and full-text search. Everything works offline, with optional sync through Automerge CRDTs and no vendor lock-in.

Worlds with rules, played turn by turn or left to evolve on their own.

Playable
Paw & Claw
A turn-based strategy game in the spirit of Advance Wars, fought by woodland armies. Raccoons, badgers, lions, red pandas, and moles fight over every thicket and creek. Built in Rust with Bevy. Play it free in the browser, or as a desktop build.

Terrarium
A societal simulation engine where LLM-powered agents form emergent civilizations. Each agent has a personality, needs, memories, and beliefs that can be wrong. You set the rules of the world, then watch for markets, hierarchies, and alliances to emerge on their own.
