Read the full Synthesia review

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.

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.
