Does Synthesia train on your data?

Yes

Synthesia Limited · Video

No. Synthesia does not train its models on your content by default, and its business tier (Enterprise) keeps your data out of training.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: No by default; Synthesia states it does not use customer inputs or outputs to pre-train its AI components; any fine-tuning on customer data only happens on the customer's written instructions.
Business-tier training: No by default; Same policy applies across paid/business tiers: customer data is not used to pre-train models, and Synthesia acts as a GDPR processor on the customer's behalf.
Training control: Not verified; No reliable training opt-out was confirmed in the sources reviewed for this profile.

Practical risk: The main governance gotcha is consent provenance for AI avatars and voices. Synthesia requires documented consent for any likeness, so an at-work user must ensure they have rights to any face or voice they upload to create a custom avatar.

How to make a decision

Check the precise account tier, written contract and intended data before approving Synthesia. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
