17yellow

A hobby project that listens to a call or talk and generates animated visual explanations. You preview them privately and choose which to share.

Audio is transcribed on your Mac. Recent transcript text goes to GPT-6 Astra with high reasoning through your signed-in Codex session. The visuals can be wrong.
