HeyGen

HeyGen is an AI video generation platform that turns written scripts into polished videos featuring realistic digital presenters. Users select or create an avatar, type or paste a script, and the system produces a spoken video complete with synchronized lip movements and natural-sounding narration. The platform also supports custom avatar creation, voice cloning, and translation of finished videos into dozens of languages.

The tool is aimed at marketing teams, educators, and businesses that need to produce large volumes of video without cameras, studios, or on-screen talent. Its browser-based editor lets non-specialists assemble professional clips in minutes, and template libraries speed up common formats like product demos and training modules.

HeyGen operates on a subscription model with free and paid tiers that scale by video length and features. Founded in 2020 and based in Los Angeles, it has grown into one of the most widely used avatar video services.
