Is this a full video editor or just a trimmer?
It is the CutFast timeline: cut, captions, text, canvas ratio, and MP4 export. One-job tools like trim and merge stay on their own pages so search intent does not collide.
Talk to the timeline. Cut the clip.
Describe the cut in plain language. CutFast keeps highlight ranges, drops filler, and exports the clip in the browser — the same job Jianying Assistant launched on 20 Sep 2026, without switching tools.
FAQ
Can I paste a YouTube or Bilibili link?
Yes. Paste the URL and open the cut editor. CutFast pulls captions when they exist, then you edit on the timeline.
Does a dropped file leave my computer?
The preview and export on this page run in the tab. Opening the full timeline is a separate step you choose.
Can I export 9:16 for Shorts?
Yes. Switch the canvas to 9:16, 16:9, or 1:1 before you export MP4.
Where do captions come from?
From the source when you paste a link, or add them in the editor. The auto caption tool is a dedicated page if you only need subtitles.
How is this different from CapCut or Canva?
Those are full creative suites. CutFast is a browser editor for one clip: get in, cut, caption, export. No project cloud and no template mall.
