HeyGen

HeyGen is an AI video generation platform that turns scripts, text, images, and slide decks into videos featuring talking AI avatars. Users can choose from more than 1,000 stock avatars or build a personal Digital Twin by recording themselves, then generate a video by typing or pasting a script, with the avatar's lip movements, facial expressions, and hand gestures synced to the generated speech. The platform includes more than 100 AI voices and supports voice cloning, and it can translate and dub existing videos into more than 175 languages while automatically adjusting lip-sync to match the new audio. HeyGen is built for marketing, sales, and learning and development teams that need to produce video content without a camera crew or studio.

Editing happens in a text-based Studio interface, where users adjust scripts, swap backgrounds and outfits, and arrange scenes rather than using a traditional timeline editor. HeyGen also offers photo-to-video animation, product and UGC-style ad creation, and an API for developers who want to generate avatar videos programmatically. Plans range from a free tier with three short videos per month to paid Creator, Pro, Business, and Enterprise tiers that increase video length, credit allowances, export resolution, and the number of custom Digital Twins available. The company states it is SOC 2 Type II and GDPR compliant and does not use customer data to train its models. HeyGen is used by companies including HubSpot, Workday, and Autodesk for training, marketing, and localization content.
