Captions AI

Captions.ai is an AI-powered video creation app known for auto-generating subtitles, and it also features a tool to create talking AI avatars.

With Captions’ avatar generator, users can produce a lifelike virtual presenter that narrates their script. The user simply types in a script or uploads audio, chooses an AI avatar character, and the app generates a video of that avatar delivering the lines with realistic lip-sync and facial expressions.

This enables content creators to make presenter-led videos (for example, a spokesperson video or tutorial) without appearing on camera themselves. Captions.ai provides options to customize the avatar’s look or even create a “digital twin” avatar modeled after the user. Backgrounds and other visual elements can be added to complete the video. By integrating captioning, editing, and avatar narration in one platform, Captions.ai streamlines the production of engaging videos for social media, marketing, or educational purposes, using AI to handle the heavy lifting of performance and post-production.
