How it works

From a voice memo to a project that already exists.

Voice in

You open Listener. Tap once. Talk for five minutes.

No prompts. No fields. No structure to figure out. Speak the idea as if explaining it to a friend at a kitchen table.

Transcription

Whisper runs locally. Your voice becomes structured text — privately, in seconds.

Speaker turns, punctuation, paragraph breaks. The audio never leaves your machine. The transcript is what the pipeline reads.

Research

Exa searches the web for competitors, prior art, and market signal. You get a brief, not a hallucination.

Real URLs. Real snippets. Each finding cited and dated. The PRD agent reads this before it writes a word.

Project foundation

Claude writes the PRD. A brand identity is generated. Jira board and Confluence space scaffold themselves.

Four specialists, four typed schemas, one validated handoff per agent. The output is what a small studio would produce in a week.

Scaffold & deploy — optional

For Pack B and C: a Next.js + Supabase repo lands in your hands. For Pack C: it's live before you close the tab.

Auth wired. Database typed. Vercel preview URL. The scaffold matches the PRD schema, not a generic template.
