HeyGen

HeyGen generates videos of AI avatars speaking a script you provide, using either a library of stock avatars or a custom avatar trained from a short recording of yourself. A key strength is automated translation and dubbing: a single video can be re-rendered in dozens of languages with lip movements adjusted to match the new audio, which is popular for training videos, product explainers, and localized marketing. The free tier allows a small number of short videos per month, enough to evaluate quality before committing; custom avatar creation and longer/more frequent videos require a paid plan starting around $29/mo. Avatar movements and lip-sync are good but can still look slightly artificial in close-up, especially with longer scripts or unusual phrasing. In October 2026, HeyGen introduced HeyGen Voice, its first in-house AI voice model, built for video. It is built into HeyGen's Avatar V video generation stack, so a video's face and voice come from one system rather than separate vendors. HeyGen offers creating a voice for free in its app; check HeyGen's official pages for current plans, limits and pricing.
