To-dos you can tick off
Short, specific actions pulled from what they said. Ticks are saved with the note.
Voice notes, already written down.
Download a WhatsApp voice note and a small window opens with the transcript, a summary and your to-dos.

Press play. It writes down what it hears.
Try the window. Download a voice note.
This is Voice Notes' own interface, rebuilt for the web and sped up. Pick a sample below, then switch tabs, tick off to-dos and ask the chat for a reply.
The samples are made up. In the app, the transcript comes from Antigravity running Gemini 3.8 Flash.
Voice note transcribed
From Downloads to done in about thirty seconds.
Voice Notes checks your Downloads folder every two seconds. When a file named WhatsApp Audio lands there, this happens.

It lands in Downloads

It's copied, not converted
The Opus file stays as WhatsApp made it. It plays in the window and still works after you clear Downloads.

Antigravity listens
The Antigravity CLI runs Gemini 3.8 Flash and returns the transcript, a summary, to-dos and the questions they asked.

The window opens on it
Right on top of what you were doing, with a notification when it's done.
Everything you'd write down yourself.
One call to the model fills all of it. You read for ten seconds instead of listening for a minute.
The questions they asked
So nothing goes unanswered in your reply.
Copy it anywhere
Summary, to-dos and questions as plain text, with or without the transcript.
A chat that knows the note
Draft a reply in their language, switch it to English, or ask what's most urgent. You still press send.
Mixed languages, written the way they were said.
Taglish stays Taglish. Arabic sits right to left beside the English around it. Flip to English when you need it.
It reads voice notes. It doesn't take orders from them.
A voice note is someone else's words. Voice Notes treats them as content to transcribe, never as instructions.
$agy -p "…" --model gemini-3.8-flash-medium --sandbox --output-format json
No auto-approve
It never passes --dangerously-skip-permissions. In headless runs, anything that needs approval, like running a command or editing a file, is refused.
Sandboxed
Each run gets --sandbox on top, and only sees the folder for that one note.
Your notes stay on your Mac
Transcripts, ticks and chats live in Application Support. The audio goes to Google through Antigravity to be transcribed, and nowhere else.
Set up in five minutes.
One download, one command-line tool and a Google sign-in. Updates arrive on their own after that.

Questions, answered.
Something else? Open an issue on GitHub.
Does my audio leave my Mac?
Yes, once: it goes to Google through the Antigravity CLI so Gemini can transcribe it. The transcript, summary, ticks and chats are stored on your Mac, in Application Support.
Does it work with the WhatsApp app, or only WhatsApp Web?
Either. It watches your Downloads folder for files named WhatsApp Audio, so any way of saving the voice note there works.
Which languages does it understand?
Whatever Gemini understands, including notes that switch between languages mid-sentence. When a note isn't in English you also get an English translation.
Will it reply for me?
No. The chat drafts replies ready to paste into WhatsApp. Sending is always up to you.
What about voice notes I already have?
The first time it runs, it lists what's already in Downloads without sending anything. Each one has a Transcribe button for when you want it.
Why does macOS warn me when I open it?
The app is signed ad hoc rather than notarized by Apple, which is common for small open-source tools. You allow it once. After an update, macOS may ask about Downloads again.
Does it cost anything?
The app is free and open source. Transcription runs on your own Antigravity account, under whatever limits Google sets for it.

Free for Apple Silicon Macs. It updates itself.
