17yellow

17yellow listens to a call or talk, transcribes it locally, and generates animated visuals that explain what is being discussed. Recent transcript text goes to Claude through your signed-in Claude Code session. Nothing is shown to anyone until you share it.

Getting started

  1. Open the DMG and drag 17yellow Private Beta to Applications.
  2. Right-click Start 17yellow.command, choose Open, and keep the Terminal window open.

Example

A segment from Tim Palmer's Royal Institution talk on chaos, and the visual 17yellow generated while listening to it. Two double pendulums start almost identically and end up in very different places.

Watch the segment on YouTube, 0:55 to 2:44

Drag a bob to set a new nearby start. together

The pendulums are a teaching model generated for this idea, not a reproduction of Palmer's apparatus.
