What Synthesia does
Synthesia converts written scripts into videos narrated by AI avatars, using a library of 125-240+ stock presenters plus custom personal avatars trained from user footage. It's aimed primarily at corporate training, onboarding and internal communications, with SCORM export, 1-click translation into 80+ languages, and SSO for enterprise buyers. Founded in London in 2017, it is one of the oldest and best-funded companies in the category.
Worth knowing: Valued near $4B as of recent funding rounds per third-party coverage; one of the two oldest companies in this list alongside D-ID.
What users complain about: G2 reviewers frequently cite the free tier's minute caps and limited avatar selection on lower plans as reasons they had to upgrade. (https://www.g2.com/products/synthesia/reviews)

Where it wins
- Widest enterprise trust/adoption in the category with SOC2, SSO and SCORM for LMS workflows
- Highest independent trust score among major competitors (Trustpilot 4.0/5)
Where it falls short
- Yearly minute pools (e.g., 360 min/year on Creator) run out fast when each training video runs 3-5 minutes
- Reddit users note avatars 'haven't fully crossed the uncanny valley,' with gestures sometimes mismatched to script tone
- Content moderation can block ordinary business scripts without explanation, with manual review taking 12-24 hours
