Explore how Perfect Freehand is used in this channel's material. It is cataloged as a term from the session Experiments with Kieran, OpenAI Live Voice inside Compound Engineering, in which Kieran experiments with adding OpenAI's live voice API to Compound Engineering's polish workflow — so you can talk to your app while it's running, and coding agents fix things in the background. That session surfaces the design questions behind the experiment and shows how the brainstorm-to-plan-to-build loop actually ran on stream. The captured handout and summary for the session don't describe Perfect Freehand's specifics, so to understand how it functions in context, explore the session itself.
