Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

• Mirage Application

  AI video model that generates and edits fully layered, editable video from text or reference clips, powering the Captions app used by over 20 million people.

• Captions Application Sold on its own

  Captions' own AI video editor: an app that takes a raw clip to a finished, captioned, edited video without a manual editing pass.

Inside Captions

• AI Edit Application Included with the parent

  One-tap video editing preset applying a full style (color grade, typography, transitions, overlays, pacing) to an entire video at once; 40+ styles across themed categories.

• AI Twin Application

  Generates a digital twin (a character that looks and sounds like an existing person) from 10 seconds of footage, powered by the Mirage Avatar X model, for unlimited new videos from a script.

• Eye Contact Application

  AI eye-contact correction inside the Captions app that finds unintentional breaks in a talking-head video's gaze — reading a script, glancing aside, nervous blinks — and adjusts the footage so the speaker looks at the camera while keeping expressions natural.
