HeyGen: review, test, pricing and alternatives (2026)

HeyGen plays in the same arena as Synthesia — AI-avatar video — but with a different temperament: where Synthesia targets enterprise and training, HeyGen bets on speed, avatar realism and a consumer audience. You type a script, pick a presenter (or clone your own), and it produces a video where the character speaks, lip-synced, in dozens of languages.

Its signature feature, the one that made its name well beyond the marketing crowd, is video translation: it automatically re-dubs an existing video into another language while resyncing the speaker's lips. The effect is striking, and it's a game-changer for localizing content without reshooting everything. Great too for personalized messages produced at scale.

The limits are worth knowing: cost climbs with video length, the free tier adds a watermark, and for long, structured training, Synthesia stays better equipped. But for fast marketing video and multilingual dubbing, HeyGen is — alongside Synthesia — our first reflex.

The lip-synced video dubbing is impressive. For avatar marketing video and localization, it's our first reflex alongside Synthesia.
