HeyGen generates video from text using AI presenters: pick or create an avatar, paste a script, and it produces a talking-head video, with translation and lip-sync into other languages. It is aimed at small marketing and training teams that need explainer, onboarding and product videos without cameras or actors. The one thing to know is that the translation feature is its distinctive strength for businesses selling across several markets.
Disclose to viewers when a presenter is AI-generated; audiences and, in some jurisdictions, regulators expect it.
Brands whose credibility depends on a real person on camera will find avatars counter-productive. Teams that only need voiceover, not a visible presenter, should look at Murf or ElevenLabs instead.
