HeyGen
AI video platform that turns text into talking avatar videos. Upload a photo, type your script, and get a presenter-style video in minutes.
What is HeyGen?
HeyGen is an AI video generator that creates talking avatar videos from text scripts and photos.
You upload a photo (or choose from 230+ built-in avatars), type or paste your script, pick a voice, and it generates a video of that person speaking your words with realistic lip sync and expressions.
Most builders use it for product demos, explainer videos, and social content where they need a presenter but don't want to record themselves on camera. It handles 140+ languages and can translate existing videos while keeping the original speaker's voice and lip movements synced.
Free plan includes 3 videos per month (up to 3 minutes each). Creator plan is $29/month for unlimited videos and 1080p exports. Custom avatars require uploading 2-5 minutes of footage of yourself speaking.
