Click a word to jump there. Drag across words (on a phone: tap the first and the last) and press Cut. Ctrl+Z undoes.
Saved you an hour of editing?
Cut Studio is free and has no watermark. A coffee helps keep it that way.
No upload. The speech recognition (OpenAI Whisper) and the cutting run in your browser. Only the speech model is downloaded, once.
Fast on a computer. With a graphics chip (WebGPU) the words of a 10-minute video are ready in one to two minutes. Phones work too, best with shorter clips.
Remove silence in three steps
Open the video
Cut Studio reads the sound and marks every pause longer than 0.7 seconds – no AI download needed for this.
Set the threshold
Move the slider: a higher value keeps more natural pauses, a lower one makes the video tighter. The breath that stays keeps speech from sounding chopped.
Check and export
Play the preview, which skips every cut, keep single pauses with a click and export the MP4.
Pauses that feel natural
Cut Studio measures the loudness of your recording every 20 milliseconds and learns the level of the room around you. Only silence longer than your threshold (0.7 seconds to start with) is cut, and a short breath stays on both sides, so the speech keeps its rhythm instead of sounding chopped. Silence before the first and after the last word goes completely.
Finding the ums
Speech recognition is trained to write clean sentences, so it often leaves out an “um” altogether. Cut Studio therefore looks twice: it removes the hesitation words the recognition did write down, and it marks stretches where you can hear a voice but no word was recognized. Those show as small 〰 chips in the text; click one to keep it.
For editors: subtitles and cut lists
Already working in DaVinci Resolve, Premiere Pro or Final Cut Pro? Take the cuts along as an EDL or FCPXML file and import them as a timeline over your original footage, at full quality. The SRT and VTT subtitles are timed to the edited version, so they line up after every cut.

Frequently asked questions
How does the silence detection work?
Cut Studio measures the loudness every 20 milliseconds and compares it with the level of the room in your recording, so it works in quiet studios and noisy kitchens alike. Only pauses longer than your threshold are cut.
Can I keep a pause?
Yes. Every pause shows as a ⏸ chip with its length; click it to keep that one, or switch pause cutting off entirely.
Is Cut Studio really free?
Yes. No account, no watermark, no limit on how long your videos are or how many you edit. Fair ads below the tool and voluntary coffees pay for the site.
Are my videos uploaded?
No. Your file is read, transcribed and cut in your browser. Our server only delivers the page and the speech model; it never sees your recording.
Which languages does it understand?
Whisper recognizes about 99 languages, from English, German, French and Spanish to Japanese and Arabic. Cut Studio detects the language by itself, or you choose it.
Does the export lose quality?
The edited video is encoded again as H.264 at a bit rate close to the original’s. If you want to keep your original footage untouched, export the EDL or FCPXML cut list and render in your editing program.
How long can a video be?
On a computer, hour-long recordings work. Phones have less memory, so clips of up to about 15 to 20 minutes are the safe choice there.
