The Key Difference
HeyGen builds avatars. Dubly.AI dubs real videos.
HeyGen was developed as an avatar platform. Video translation is an add-on feature, not a core product. Dubly.AI was built from the ground up specifically for video dubbing — with its own Lip Sync 2.0 model that scores 96.4 out of 100 in independent tests (HeyGen: 76.8). For companies that need a specialized AI video translator, the difference is immediately visible.
