HeyGen

AI avatar video for training, marketing, and comms. Enterprise default.

Studio for AI presenter videos — pick or clone an avatar, type a script in 140+ languages, and render a talking-head video. The go-to for L&D, onboarding, and corporate comms.

Turn a photo and voice into talking, expressive characters.

Hedra generates lip-synced, expressive talking-character video from a single image plus audio or a script. Its Character-3 model handles facial performance and emotion, and a Live Avatars tier streams those characters in real time for conversational AI agents.

Real-time conversational video AI and digital human replicas.

A developer platform for building face-to-face AI agents that see, listen, and respond in live video through its Conversational Video Interface (CVI). It also generates personalized videos at scale from digital replicas of a real person. Built on Tavus's own models — Phoenix for rendering, Raven for perception, and Sparrow for conversational timing — with the ability to plug in custom LLMs and text-to-speech.

AI video editor and avatar creator for short-form, talking-head content.

An AI video app for creators that auto-edits talking-head footage — generating captions, inserting B-roll, correcting eye contact, and dubbing into other languages. Its AI Creator mode renders a talking video from a script using AI personas. Built by Mirage on its own generative-video foundation model.
