Call Assistant App Icon

Call Assistant

Meetings, minus the bot

macOS · Apple Silicon Private beta

A native Mac app that sits on your side of the call. It captures both sides through its own audio device — no bot ever joins the meeting — transcribes locally with Whisper, and turns what was said into actions you can actually track. Works with Teams, Meet, Zoom, or anything else making sound on your Mac. Your recordings and transcripts stay on your machine as plain files; the AI features run on your own Claude API key, and switching them off means the app makes no calls at all.

Your mic and the meeting's audio arrive as two separate streams, so every line is already labelled. Fact-checks, commitments and open questions surface while you're still talking. ⤢ enlarge

No bot, no setup

One admin prompt installs its own audio device. The meeting app never sees a guest it didn't invite.

Transcribed on your Mac

Whisper runs locally. Two streams mean You and Remote labels come for free, with no guesswork.

You review before it saves

Summary, actions and decisions arrive as a draft with the quote each one came from. Edit, then keep.

Nothing phones home

No telemetry or analytics. Bring your own Claude key, and every AI feature has an off switch.
