An AI note taker for Zoom that never joins the call

23 October 2026

OpenNoteTaker (opennotetaker.app) is an AI note taker for Zoom meetings you join in a Chrome or Edge tab. It records the tab’s audio and your microphone, transcribes them in the page, and pulls out decisions and action items — with no bot in the participant list and no upload of the recording.

First: Zoom in the browser, not the desktop app

This is the one thing to know before you rely on it. This AI note taker for Zoom hears the sound of a browser tab. The Zoom desktop app is not a tab, and no browser can reach its sound, so a call running in the installed app is not what it records. There are two ways through:

• Join the meeting from your browser. Open the invitation link in Chrome or Edge, and when the page offers to open the Zoom app, take the option to join from the browser instead. The call then runs in Zoom’s web client, in a tab, and OpenNoteTaker records it like any other tab.
• Or install a loopback device, which presents your computer’s output to every application as if it were a microphone: BlackHole on macOS (with a Multi-Output Device so you still hear the call), VB-Cable or “Stereo Mix” on Windows, and the existing .monitor input on Linux. Pick it under Choose which input, and turn off Clean up the sound, which is built for a real microphone.

The browser option is Zoom’s to give. Zoom’s support pages say the “join from your browser” link is on by default, that account owners and admins can turn it off, and that it does not appear when the host has end-to-end encryption on — those meetings send everyone to the app. If you see no browser option, the loopback route is the one left.

Using the AI note taker for Zoom, step by step

1. Join the Zoom meeting in a Chrome or Edge tab, as yourself.
2. Press Record a meeting. The optional extension recognises Zoom meeting links and the web client as they open and offers to start; it never records anything itself.
3. Read out the consent screen. It opens before every recording and cannot be skipped.
4. Pick the Zoom tab in the share dialog with “share audio” ticked.
5. Stop when the call ends, and let it transcribe in the same tab.

Tab audio — which is everyone else on the call — can only be captured in Chrome and Edge, and only when you pick the tab and tick “share audio”. Recording your microphone alone is not enough: echo cancellation removes everyone else, and the app warns you if the tab is switched off mid-call.

Zoom transcription that stays on your machine

Zoom transcription here is Whisper running inside the page, in 99 languages, so the AI note taker for Zoom never sends the audio anywhere. The model is downloaded once and cached; after that it works offline. The language is detected every few seconds, which keeps a bilingual meeting readable. Speakers are separated on your device: good with two or three distinct voices, poor with crosstalk, and easy to correct by hand.

What you keep is a note: decisions, action items, deadlines, open questions and topics, each linked to the moment it was said, plus search across every meeting and exports in SRT, WebVTT, text, Markdown, JSON, CSV and HTML. All of that is free. AI-written minutes, questions across your library and translating a finished transcript use credits on our backend ($5 for 1,000, with the price of each job on the button). They send transcript text, never audio.

When you are not the host

Zoom’s own recorder is a host permission, so a guest usually has no record button. This AI note taker for Zoom does not go through that permission: it hears your own tab, so there is no guest for the host to admit and nothing new in the participant list. That also means Zoom shows nobody a recording notice. Say it yourself, at the start, and stop if anyone objects — the consent screen gives you the words.

What it cannot do

• The Zoom desktop app, without the browser or a loopback device (above).
• Firefox and Safari, which do not give a page tab audio.
• Copy the host’s or Zoom’s cloud recording. This is your own transcript, visible to nobody else.
• Tell you whether you may record. That depends on where everyone in the call is.

OpenNoteTaker is an open-source AI note taker (MIT or Apache-2.0). For the longer story of Zoom’s host rules, see recording a Zoom meeting as a participant. The same method works in Microsoft Teams on the web, and here is everything that is free.
