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.

Works with
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.
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.
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.
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.
Record your screen, mic and camera in the browser, then polish the result. Backdrop, rounded corners and zooms, all local. Nothing is uploaded, no watermark.
Clean up muddy audio and reduce background noise in a video, in your browser. No upload, your footage and audio stay on your device.
Make a quiet video louder or tame loud audio in your browser. Adjust volume in dB without uploading your clip.
Add auto-captions to any video in your browser. On-device transcription with viral caption styles, no upload, your footage and audio stay private.
Record how-to and onboarding walkthroughs for your help center, caption them on your device, and export without uploading customer accounts or internal tooling.
Turn podcast episodes into captioned vertical clips for social. Transcribe and reframe in your browser without uploading raw audio or video.
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.
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.
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.
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.
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.
