Captions is an AI-powered video creation and editing platform designed for content creators, marketers, and businesses producing short-form video content. The platform uses proprietary foundation models specifically trained on social video formats to generate and edit professional-quality videos with minimal manual effort.

The core technology centers around the Mirage AI model, which powers features like automated video editing, AI-generated avatars, and multilingual dubbing. Users can create videos from scratch using AI Creator, which generates talking videos with 3D avatars without requiring any live recording. The AI Edit feature watches and edits videos in real-time by applying selected editing styles, handling cuts, transitions, zooms, and effects automatically.

The platform includes advanced subtitle generation in over 100 languages with customizable styling, background noise removal, eye contact correction, and video resizing capabilities. The chat-based editor allows users to make editing changes through simple text commands, functioning like having an on-demand editor available 24/7. Video translation capabilities enable creators to dub content into 28+ languages with synchronized lip movements that match the translated speech, expanding global reach while maintaining authentic visual presentation.
