ibara gives AI agents computers of their own: they use the browser and desktop apps there while you keep working on yours.
A multiplayer browser shooter where detective rats throw bouncing cheese balls across a run-down noir city.
A local second brain built on GBrain, with TypeSafe Jev helping rank searches and suggest connections between pages.
Conference programming and speaker management: proposals, review, speakers, scheduling and the public agenda, connected in one place.
Masthead keeps a local record of your coding-agent sessions and helps you turn the useful parts into pages.
A spending companion built around one number: Spendable Cash Today.
Builds a room-by-room deep-clean calendar from rooms, cleaning capacity, dates and blackouts, and exports it when the work fits.
A planner that turns a brain dump into outcomes, steps and a schedule that respects your capacity and constraints.
A playful benchmark: coding models get the same frozen brief, a prestigious launch website for whole milk, and the gallery keeps what each one made.
A plain guide to the computer a self-hosted AI agent runs on: pick yours to see whether it's enough, what it costs to run, and when a Mac mini is worth it.
A persistent Android assistant I'm still building: goals, tasks, capabilities and evidence belong to the system, not to a single chat.
