CapCut: Free social-first video editor from ByteDance with auto-captions built in.
CapCut is ByteDance's free, social-first editor. Distribution is massive — desktop, web, and mobile apps ship with auto-captions, effects, and templates tuned to TikTok trends. It's the default free editor for millions of creators.
The concerns are ownership and jurisdiction. ByteDance is subject to ongoing US privacy and national-security reviews; several government agencies and enterprises have banned CapCut alongside TikTok. Business users, US public sector, and privacy-conscious creators actively search for alternatives.
