What It Does
HeyGen creates AI avatar videos, similar to Synthesia, with a generous free tier. Its standout feature is Video Translate: upload an existing video of yourself speaking and HeyGen translates it into another language, cloning your voice and lip-syncing the avatar to match. It also offers Instant Avatar creation from a two-minute selfie video, branded templates, and integration with teleprompter workflows.
Setup in 5 Minutes
.
- The free tier includes three videos per month (up to three minutes
each).
- Choose a stock avatar or create your own Instant Avatar by
recording a two-minute video following the on-screen prompts.
- Write your script, select the avatar and language, and generate.
