Captions AI

Captions is an AI video creation platform built for social media creators, marketers, and educators who want to produce polished video content without a traditional editing workflow. Its core tools: AI Avatar (generates a talking-head video from text, no camera needed), auto-captioning with speaker diarization and word-level sync, and a text-based timeline editor where you describe edits in plain language.

The platform is designed for speed — users can go from a script to a publish-ready vertical video in minutes. Auto-captions are accurate enough for public-facing content in most cases, with manual correction tools for high-stakes outputs. AI Eye Contact correction automatically adjusts subjects' gaze to face the camera even when reading from notes.

Captions operates primarily on mobile (iOS and Android) with a growing web interface, positioning it as the creator-first alternative to more desktop-oriented tools like Descript or CapCut. Its AI Avatar product competes with HeyGen and Synthesia in the talking-head market but targets individual creators rather than enterprise customers. Captions has since merged with Mirage Studio, folding AI image/video generation tools into the platform, and added one-tap video translation with lip-dubbing across 100+ languages.
