What Replay records on Mac and how to verify it
See which windows and audio sources Replay captures in Google Meet, Zoom and Microsoft Teams, and verify the result with a short test call.
Supported calls and capture scope
Replay by Nika Sakandelidze is a bot-free meeting recorder for Apple silicon Macs running macOS 26 or later. It saves a local video with separate tracks for the call app’s audio and your microphone. The video source depends on how you start recording.
| Call | Video source | What to check |
|---|---|---|
| Google Meet in a browser | The browser window you select. If the call title is unrecognized, choose the window manually. | Keep Meet visible in its own window. Audio comes from the browser app and can include other tabs or windows, so pause unrelated browser audio. |
| Zoom Mac app | The selected Zoom window, or Zoom windows on the call’s display if you start from Replay’s call detection prompt. | Use the window picker when you want the video to stay on a specific window. Use the call prompt if you expect the call to move to another Zoom window on the same display. |
| Microsoft Teams Mac app | The selected Teams window, or Teams windows on the call’s display if you start from Replay’s call detection prompt. | Replay 0.2.10 introduced the option to follow what you present in Teams when it detects the share. Check Settings → Recording → Record what I share in the call. The two audio sources continue while the video follows the share. |
Verify a recording with your setup
- Open a test call with someone who agrees to be recorded. Use the same meeting app, audio input and display you plan to use later. Give Replay Screen & System Audio Recording and Microphone access in macOS.
- Start recording and ask the other person to show a card that says ‘Violet prototype’. With headphones on, say ‘microphone check’, then ask them to say ‘meeting audio check’. The You meter should respond to your phrase and Them to theirs.
- If you plan to present in Teams, briefly share a test document with ‘Delivery’ on it. Say another phrase on each side while sharing. With the share setting enabled, check that the saved video shows the call, then the document, then the call again, with both sides audible during the share.
- Stop and open the clip in Replay. Check the video and both voices. Transcribe it to check the Me and Them labels and jump from a transcript line back to the recording. The recording’s menu has Show in Finder if you want to inspect the local recording.mov and transcript files.
What we verified with synthetic recordings
On November 9, 2026, we checked Replay 0.2.14 on Apple silicon with macOS 26.5.2. The checks used generated media, sample window data and an isolated library. Use the test call above to verify live capture with your browser, app version and audio devices.
| Check | Observed result |
|---|---|
| Meet window picker | Recognized Meet windows appeared first. An unrecognized browser window could be selected manually without triggering automatic call detection. |
| Teams share detection | Sample window and display layouts resolved to the intended share target. Ambiguous simultaneous shares did not select a new target. |
| Browser video export | A generated HEVC MOV with separate 440 Hz and 880 Hz tones became an H.264 video with one AAC track containing both tones. The original file’s checksum stayed the same. The check ended at local export before any upload. |
| Read-only MCP | The fixture contained one 14-second recording and transcript lines at 00:03 and 00:09. Replay’s bundled local command found the recording, returned its notes and marker, and returned only the 00:09 transcript line when asked for seconds 8–13. All fixture file checksums stayed the same. |
What works offline and what leaves your Mac
Activate Replay online once per Mac and download your speech language model. Replay can then record and transcribe on the Mac offline. A live meeting still uses its provider’s connection. Generated notes require Apple Intelligence to be enabled and available.
Share Link uploads a separate video copy and opens public access for 1–12 hours. The original, transcript and notes stay on the Mac. Expiry and revocation stop new playback requests. Anyone who saved or buffered the video can still have those bytes.
Replay’s read-only MCP integration needs a client on the Mac that can launch the local Replay executable and communicate with it over standard input and output. A connected cloud assistant can receive the parts of your local library it reads.
