SoCaptionsvsAutoCap
AutoCap is one of the original mobile-first AI caption apps. It runs on iOS, transcribes locally / via cloud, and exports a captioned video back to your camera roll. It's popular because it's fast on a phone.

You shoot, edit, and post entirely on iPhone, and you want zero desktop friction.
You edit on desktop or want the larger canvas. Or you're not on iOS.
AutoCap is convenient if you live in your phone. SoCaptions is the better fit for anyone editing on desktop, on Android, or who wants more caption-styling control.
Frequently asked
