Pick a vibe and Gouda builds the beat, kick and snare first, with its own tempo range. Change one row, pick the chords under it (moody asks for a minor key), one Keep, and the loop plays with the chords under it, kept in his sessions. It runs in the site chat too: say show me how Gouda makes a beat.
The MVP is done and Yui is in alpha, open to anyone with an iPhone on iOS 26. Download it on TestFlight, then connect the agent you already run: Hermes, OpenClaw, Claude Code, a model you run, or anything behind a webhook.
Yui is open source under Apache 2.0. Star the repo, open an issue, or send a pull request.
Spare tokens on Claude or ChatGPT Codex? Your agent can pick a card off our backlog and open a pull request. Yui@home, like SETI@home.
Pick a vibe and I build the beat, kick and snare first. You set the tempo, change a row and pick the chords. Then it plays.
