The bottom line

Privacy matters — whether you're editing client work, medical video, or anything you wouldn't want on someone else's server. Or if you're tired of paying monthly. $49 once, on your Mac, forever, with WCAG compliance tools built in.
Common questions
Is Submagic better than Vosuba for social media?
Submagic is optimised for short-form social content with trendy animated templates. Vosuba has fewer social-specific templates but is better for longer-form video, institutional captioning, and any content where privacy or compliance matters. If you only make short TikTok/Reels clips and don't handle sensitive content, Submagic's UX is optimised for that workflow. For everything else, Vosuba offers more capability at a fraction of the lifetime cost.
Why would I pay $49 for Vosuba when Submagic has a free tier?
Submagic's free tier is heavily limited — videos are typically watermarked and capped by duration or volume. Vosuba's free tier offers unlimited SRT/VTT exports with no watermark on subtitle files. The $49 Creator tier removes the video burn-in watermark and unlocks all models, presets, and compliance tools. If you caption regularly, Submagic's $24/month subscription costs more than Vosuba in just over two months.
Does Submagic work on Mac?
Submagic is browser-based and works on any OS. Vosuba is a native macOS desktop application. Vosuba's advantage is that being native means no uploads, no bandwidth dependency, and offline operation — not possible with a browser-based tool.
