Captions (formerly Captions AI) is an AI-powered video creation and editing platform designed for content creators, marketers, and businesses. The app enables users to create professional-quality videos with automated captions, AI-generated avatars, multilingual dubbing, and smart editing tools. Its standout feature is the AI Twin, which creates a realistic digital clone of the user that can deliver scripts in videos, enabling scalable content production without repeated on-camera filming. The platform supports dubbing videos into over 29 languages with synchronized lip movements that match the original speech, making it easy to expand content reach to global audiences. Captions also offers an AI Creator tool for generating videos using customizable 3D avatars, automated eye contact correction, background removal, and teleprompter functionality. The app uses smart cuts to automatically remove filler words, silences, and retakes, streamlining the editing process. Animated caption styles with customizable fonts, colors, and effects help boost viewer engagement on social media platforms. Additional features include AI script generation, scene detection, auto-zooming, and direct publishing to TikTok, Instagram, YouTube, and other platforms. Captions has become one of the most popular video editing apps on the App Store and Google Play, with millions of downloads and widespread adoption among short-form content creators.
