Captions

Captions is a mobile-first AI video editing app aimed at people who film talking-head content. Its most-used feature is AI eye contact correction: even when you're looking at notes or a script rather than the lens, Captions adjusts your gaze so it appears you're looking directly at camera. Auto-captioning works across multiple languages, and the background removal doesn't need a physical green screen. The translation feature goes further than subtitles — it re-dubs the audio in another language and adjusts lip movements to match. Captions also cuts filler words, adds auto-zoom at key moments, and can suggest B-roll inserts. It has over 15 million downloads, which is a reasonable signal that the core features work. The trade-off is that it's built almost entirely around talking-head formats and the desktop experience lags behind the mobile app.
