CapCut is a video editor made by ByteDance, the company behind TikTok, and it is built around the short, vertical videos people post to TikTok, Instagram and YouTube. It runs in a web browser, as a desktop app and on phones, and the three versions share the same basic layout, so what you learn on one carries over.
Most of CapCut is ordinary editing — cutting, adding text, music and transitions by clicking — with AI tools sitting alongside as buttons. The ones a beginner reaches for first are automatic captions (CapCut listens to the speech in your video and types it out as on-screen text, timed to the words), text-to-speech, background removal and noise clean-up.
It also makes video from scratch. Its AI video maker turns a script you paste in into a narrated video, and its AI video generator turns a written description into a short clip using ByteDance's Seedance models (the model is the AI "brain" that does the actual work). CapCut currently names two: Seedance 2.5 and Seedance 2.0 Mini.
Why a beginner picks it over a desktop editor such as DaVinci Resolve: CapCut is designed to get a phone-shaped video posted quickly, with templates you fill in and captions in a couple of clicks. It gives up fine control to get there, which is the right trade for social clips and the wrong one for a long film.
