Getting started
- 1
Record something
Open Gasbag and press record. The microphone is on by default; switch on Computer audio to capture the other side of a call. macOS will ask for Microphone access and, if you chose computer audio, System Audio Recording. Gasbag never needs Screen Recording. When Zoom, Teams, FaceTime or a browser starts using the microphone, Gasbag offers to record the call. It only offers. The shortcut Control Option Command R starts or stops a recording from any app.

Let it transcribe
The transcript is written on your Mac, with nothing to install and no account. Speaker detection names people Speaker 1, Speaker 2 and so on until you rename them. Import takes files or whole folders and skips anything already imported, and Import from Voice Memos brings memos in with their titles and dates.

Connect an assistant, if you want one
Settings, then AI Access. Nothing is readable until you say so: share a folder, or share one recording on its own, with Claude or ChatGPT. Letting the assistant write is a separate switch from letting it read. Its notes are saved as Markdown beside the recording.
- 4
Use more than one Mac
Settings, then Other Macs: show a code on one Mac and type it on the other. Whenever both are open on the same Wi-Fi, each sends the other its new recordings, transcripts, folders and notes, encrypted and directly, never through a server. What an assistant may read is still set on each Mac.
- 5
Lock it, if others use your login
Settings, then Privacy, then Lock My Library. Your recordings move into an encrypted disk image that opens only with a Gasbag password, with a recovery key for a forgotten one. Gasbag locks when the Mac sleeps, the screen locks or it sits idle.
Your recordings live in Library, Application Support, Gasbag, Recordings, as ordinary audio files with the transcript beside them and Markdown for anything an assistant wrote. Deleting a recording moves it to a Removed folder rather than destroying it, and a note in that folder explains how to put one back.
Requirements
- macOS 15 or later, on Apple silicon or Intel.
- Microphone access, and System Audio Recording if you record the other side of calls.
- An internet connection to check the licence every few days. Recording, transcription and speaker detection never use the network.
Your licence
- One key covers two Macs. It is checked every few days and keeps working for 30 days without the internet.
- The licence is yours to keep and includes two years of updates. After that, the version you have keeps working for good; only newer versions stop arriving.
- Your key and download link arrive by email the moment the payment goes through. The download link lasts seven days. If it has expired, the link in your key email will send you a fresh one, or write to us.
- A refund switches the key off. Questions about a purchase, a key or an invoice: write to us and include the email address you bought with.
