Captioned video export

Version 2.2 adds Word Sync Studio so each word can hit on the beat, then export a captioned video or SRT. Import a video, write a hook, add timed caption cards, preview short-video safe zones, run Timing Audit, and export locally.

What Hook Caption includes:

Hook Caption is intentionally not a social network, template marketplace, or cloud editing account. It is built for creators, students, small businesses, coaches, and anyone posting short videos who wants readable captions and a cleaner export workflow.

Your videos and caption text stay on device unless you choose to export, save, or share them. Hook Caption does not include ads, analytics SDKs, tracking SDKs, or account sign-in.

Privacy

Private by design

Hook Caption does not require an account and does not include third-party advertising or analytics SDKs. Content you create stays in the app on your device unless you explicitly export or share it. See the privacy policy.
