Synthesia's avatars produce natural lip-sync and are generally convincing for training and corporate content. For highly customer-facing or emotional content, human video remains more natural — AI avatars work best for informational content where the script matters more than personal connection.
Both offer similar AI avatar video capabilities. Synthesia has a longer track record and stronger enterprise focus. HeyGen is often considered stronger for marketing-focused video content and has competitive pricing. Both are worth evaluating with a trial before committing.
