Vosuba vs CapCut
Offline subtitle studio vs free cloud editor
CapCut is free and powerful — but it uploads your footage to ByteDance servers. Vosuba keeps everything on your Mac. Here's the full picture for subtitle workflows.
Quick answer: Vosuba is an offline Mac subtitle tool ($49 one-time) that keeps your footage on your device. CapCut is a free cloud video editor owned by ByteDance (TikTok) that uploads footage to its servers. Vosuba exports SRT/VTT/ASS subtitle files for YouTube and professional tools — CapCut does not export standard subtitle formats. Vosuba also includes WCAG compliance, AI voiceover, and batch processing.
🔒 Data Handling Difference
CapCut's auto-caption feature processes video on ByteDance (TikTok parent company) cloud servers. Their privacy policy grants broad usage rights to uploaded content. Vosuba processes everything locally on your Mac — your footage never leaves your machine, and no account is required.

The bottom line
Use CapCut if…
You need a free, general-purpose video editor for TikTok, Reels, or Shorts. CapCut excels at templates, transitions, effects, and quick social media edits. It's best when speed and visual flair matter more than subtitle export quality or data privacy.
Use Vosuba if…
You need professional subtitle files (SRT/VTT/ASS), WCAG compliance, AI voiceover, or you work with sensitive footage that shouldn't leave your machine. Vosuba is the right choice for YouTubers, editors, and institutions who need export-ready captions — not just visual overlays.
Common questions
Is CapCut safe for private or unreleased footage?
CapCut is owned by ByteDance (the parent company of TikTok). When you use CapCut's auto-caption feature, your video is uploaded to ByteDance servers for processing. Their terms of service grant broad rights to uploaded content. If you work with unreleased footage, client projects, or confidential material, an offline tool like Vosuba keeps your files on your machine — nothing is ever uploaded.
Is CapCut really free?
CapCut's basic features are free, but premium effects, advanced AI features, and commercial-use licences require CapCut Pro ($7.99/month or $74.99/year). Free exports may include watermarks on certain features. Vosuba's free tier offers unlimited SRT export with no watermark on text-based subtitle files.
Can Vosuba do everything CapCut does?
No — they serve different purposes. CapCut is a general-purpose video editor with transitions, effects, templates, and social media integration. Vosuba is a specialist subtitle and voiceover studio. If you need professional subtitle export (SRT, VTT, ASS), WCAG compliance checking, AI voiceover, or batch processing — Vosuba is the better tool. If you need video cuts, transitions, and TikTok templates, CapCut is more appropriate.
Does CapCut export SRT files?
CapCut's auto-caption feature generates styled text overlays but does not export standard SRT, VTT, or ASS subtitle files. This means captions created in CapCut cannot be imported into YouTube's subtitle system, DaVinci Resolve, or other professional tools. Vosuba exports all three formats natively.
