Try it freeMeeting tab and microphone recording
Start free, upload the downloaded recording, and get searchable text, speaker labels, timestamps, summaries, action items, and document exports.
Capture the audio already playing in your meeting tab together with your microphone. The recorder does not join the call as a participant, add a bot to the guest list, or require access to your meeting account.
The recorder uses the tab-sharing controls built into Chrome and Edge. Choose the tab running Google Meet, Zoom Web, Microsoft Teams, or another browser meeting, turn on tab audio sharing, and allow microphone access.
Meeting capture, audio mixing, preview, and download happen locally in your browser. The recording is not uploaded to or stored in our cloud. It only leaves your device if you separately choose to upload the downloaded file for transcription.
Stop the recorder to preview and download one combined audio file. Keep the file as your meeting recording, or upload it to InstantTranscriber for searchable text, speaker labels, timestamps, summaries, action items, and document exports.
Yes. This recorder captures the meeting tab and your microphone in your browser. It does not join the meeting as a participant or invite a recording bot.
Use a current version of Chrome or Edge on desktop. Tab-audio capture depends on the browser sharing picker, and support in Safari, Firefox, and mobile browsers is not guaranteed.
Yes, when the meeting runs in a browser tab that Chrome or Edge allows you to share with audio. Select that exact tab and make sure tab audio sharing is enabled.
Yes. Preview and download the combined audio file for free. Transcription is an optional next step.
No. Recording, audio mixing, preview, and download run locally in your browser. Your audio is only uploaded if you later choose to submit the downloaded file for transcription.
Recording and consent rules vary by location and organization. Tell participants and obtain any consent required by applicable law and workplace policy before recording.
