Read the full HeyGen review

HeyGen makes it easy to create talking-head videos from a script using AI avatars, or to translate an existing video into another language with lip-sync. It is the standard tool for L&D teams, marketers and creators who need scalable video without a studio. Quality of the top-tier avatars is convincingly close to real recordings.

Synthesia is the enterprise pick for AI video. It offers custom avatars, a workflow tailored to L&D and internal comms, SOC 2 compliance and team features that IT departments actually accept. Not the flashiest quality, but the most trusted for corporate use.
