This document sets out the rules for using Synthesia's AI video services. You own the data you bring in, but Synthesia owns its platform and content, and you cannot recover fees already paid if the relationship ends early. You are responsible for making sure your use of the service—including what content you generate—follows the law, and you must confirm that anyone whose voice or likeness you use for a Custom Avatar has consented.
These Terms of Service establish the contractual framework governing Synthesia's provision of AI-powered video generation services to Customers. Synthesia retains full ownership of the Services, their components, and Synthesia Content, while Customers own their Customer Data as between the parties. The agreement allocates legal compliance responsibility for content use and generation to the Customer, including obligations to verify age and obtain free and informed consent before creating Custom Avatars. Synthesia's aggregate liability is capped at fees paid in the twelve months preceding the last liability-triggering event, with full exclusion of indirect, consequential, and similar damages for both parties. Synthesia provides a contractual defence and indemnification to Customers against third-party copyright infringement claims traceable to Synthesia's own creation or development of AI components.
As a user, you must ensure that every person whose voice or likeness you use to create a Custom Avatar is above the applicable legal age and has freely and informedly consented—this obligation sits with you, not Synthesia. You are also responsible for ensuring your use of the Services and any content you generate complies with applicable law. Fees are paid in advance, cannot be cancelled, and are non-refundable except where the Contract expressly states otherwise. If Synthesia makes a material change to the Contract, it must give you reasonable advance notice by email or through the Services before the change takes effect, giving you an opportunity to respond before new terms bind you.
