What HeyGen is
HeyGen is the reference point in avatar video: scripts and photos become presenter-quality videos, with voice cloning, multilingual lip sync and API production at scale.
What you can do with it
- Generate presenter videos from text
- Clone yourself for reusable presentations
- Translate videos with synced lips across languages
- Produce training and marketing batches
- Integrate production via API
Who it is for
- Marketing and L&D teams
- Cross-border content operations
- Product and course creators
What to watch out for
- Cloning your own or others' likeness and voice requires consent; presenter clones must be documented
- Translated videos need native review; lip sync does not fix wrong phrasing
- Synthetic presenter content should be disclosed where platforms require it
- Vendor scale figures are marketing; test output on your content

Free entry is described; production volumes need plans.
