Record your screen with audio, system sound and mic

A silent screen recording is half a recording. Supercut captures your voice and the sound coming out of your computer while it records the picture, and keeps the microphone on its own track so you can balance it, clean it or drop it later. What you can capture depends on where you record: the desktop app takes the audio of the whole machine, and the browser takes the audio of a tab you share.

How it works

  1. 1

    Pick your sound sources

    Choose what to record, then turn on your microphone. In the desktop app you can also take the audio playing on your machine. In the browser, tick the share audio box in your browser’s own dialog when you pick a tab.

  2. 2

    Record with a count-in

    A short count-in gives you time to get your first line ready. Pause and resume whenever you need to, and the paused time is folded out of the final length so the audio and the picture still line up.

  3. 3

    Balance the tracks and export

    The take lands on the timeline with your microphone as a separate track. Raise it, reduce background noise, add captions, then export. Every step runs on your device.

Tips

  • Share a tab, not a whole screen, when you need computer audio in the browser.
  • Use the desktop app for audio from apps outside the browser.
  • Wear headphones so your microphone does not pick the computer audio up twice.
  • Denoise first, then raise the level, in that order.

Why it stays private

Supercut decodes, edits and exports your video entirely in your browser with WebAssembly. Your footage is never uploaded, the only thing that leaves your device is the text of your prompt, so the AI knows what edit to plan. Read more in our Privacy Policy.

Frequently asked questions

Can I record computer audio, not just my microphone?

Yes. The Mac and Windows apps record the audio playing on the whole machine alongside the picture. In the browser, Chrome and the other Chromium browsers can capture the audio of a tab you share, so pick a tab rather than a whole screen when the sound matters.

Why did my browser recording come out silent?

Browsers only include audio if you ask for it in their own share dialog, and the option is offered for a tab rather than a whole screen. Share the tab and tick the share audio box. For the audio of your whole machine, including apps outside the browser, use the desktop app.

Is my microphone a separate track?

Yes. Screen, microphone and camera are recorded separately, so you can raise your voice over the computer audio, clean it up, or remove it altogether without touching the picture.

Is my recording or my audio uploaded?

No. Recording, transcription, editing and export all happen on your device. Nothing is sent to a server, so there is no hosted copy of what your microphone picked up.

Can I fix the audio afterwards?

Yes. Reduce steady background noise, adjust levels, or add captions timed to your speech, all with the same on-device engine that handles the rest of the edit.
