audio-energy clip finder · 6 formats · runs entirely in your browser
Drop a video to find its best moments
Peakcut scans the audio for energy spikes — laughs, shouts, music hits, excited speech — drafts captions for each one, and exports clips in six ready-to-post lengths. Nothing leaves your device.
MP4, WebM, or MOV · works best under ~500MB
Load from a direct video link
This works for links that point straight at a video file (your own storage, a CDN, a direct .mp4/.webm URL). It can't reach into YouTube/Instagram/TikTok pages — browsers block that, and there's no server here to fetch on your behalf.
Got a link to a YouTube/Instagram/TikTok post instead? Grab the actual file first on a separate site, then come back and drop it in, or paste the direct file link it gives you.
About link-pasting: a browser can't download a video directly off a YouTube/Instagram page — there's no backend here to do that fetching, and pulling video off those platforms isn't something this tool does for you automatically.
