Can I vibe code Granola?

AI notepad that enhances your meeting notes with the transcript.

🟡Kinda — with gapsest. a weekend

Granola's trick is capturing system audio locally (no bot joins the call) and blending your typed bullets with the transcript into polished notes. The blend part is prompt engineering you can own in an afternoon. The catch is system-audio capture on macOS — it needs a native app with an audio driver or ScreenCaptureKit, which agents can scaffold but you'll debug. If you'll accept mic-only capture in a browser, this becomes a one-sitting build.

The one-shot prompt
Build an AI meeting notepad web app. During a meeting I record my mic (MediaRecorder) while typing rough bullet notes in a textarea, both timestamped. On stop: transcribe the audio, then run an LLM merge that produces structured notes — my bullets expanded and corrected using the transcript, plus decisions and action items with owners — shown side-by-side with my raw bullets. Meetings list with search; one-click copy as markdown and email-to-me. Keep the merge prompt in an editable file and show me the template. Next.js + Postgres + object storage, deployable to Vercel.
Paste into Claude Code, Codex, or your agent of choice — then steer. Learn the moves in Prompt Engineering.
What you build

A meeting notepad: record (mic, or system audio if you go native), type rough bullets during the call, and on stop an LLM merges bullets + transcript into structured notes with actions.

What you give up
  • Silent system-audio capture with zero setup
  • Calendar awareness and automatic meeting detection
  • Their note templates tuned per meeting type
  • Cross-meeting ask-your-notes chat
Why people still pay

It disappears into the workflow — no bot in the meeting, no behavior change, notes just get better. Invisible capture is genuinely hard to DIY.

Actually build it

A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
