Tunepick

pick three, make a song

A music toy with no wrong notes. Every round an LLM writes three options — a new layer or a fresh section — and you pick one. Keep picking and a track grows out of your taste, in whatever genre you asked for.

a station for your models

A native Mac app that runs local models next to Claude, OpenAI and friends, routes each request to the cheapest capable one, and keeps working after you close the window. One thread, many backends.
