Why choose HeyGen rather than Elai?
Whilst sharing many core features, HeyGen's avatar quality and customisation capabilities are unrivalled. For creating highly personalised videos, HeyGen offer more avatar styles, a wider range of video templates and more languages.
Avatar
HeyGen offers more than 250 stock avatars, alongside bespoke AI outfits, studio avatars and distinctive FaceSwap features. Its lip-sync technology outperforms Elai, which provides only 120 stock avatars and does not include the FaceSwap feature.
Template
HeyGen provides access to more than 400 professional video templates, with the library updated frequently. Elai provides just over 160 templates, giving HeyGen users an 88% advantage when creating and customising polished videos quickly.
Voice features
HeyGen enables users to adjust AI voice speed and pitch, upload personal voice recordings or record online — a capability that Elai does not offer. HeyGen's multiple user seats and guest access support team collaboration from any location, making the video creation process more efficient.
