By uploading content to Synthesia, you give the company a broad license to use, copy, and adapt that content to run and improve the platform.
This analysis describes what Synthesia's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
The license includes use for 'improving and developing the Services,' which may mean uploaded content, including voice recordings, scripts, or human likeness data, could be used to train or refine Synthesia's AI models, though the agreement states this is subject to the Data Processing Agreement and Acceptable Use Policy.
Interpretive note: The scope of 'improving and developing the Services' is not precisely defined in the document; whether this encompasses AI model training on customer-specific content requires review of the separately referenced Data Processing Agreement.
Customers who upload proprietary content, recorded voices, or human likeness data should be aware that the license granted covers service improvement, which may include AI model training activities subject to the terms of the separately referenced Data Processing Agreement.

"You grant Synthesia a non-exclusive, worldwide, royalty-free license to use, host, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, and display Customer Content solely to the extent necessary to provide the Services and as otherwise permitted under this Agreement, including for the purposes of improving and developing the Services.— Excerpt from Synthesia's Synthesia Terms of Service
REGULATORY LANDSCAPE: This license provision engages GDPR and UK GDPR where Customer Content includes personal data, as the lawful basis for processing must be established for each use, including AI model improvement. The EU AI Act imposes specific obligations regarding transparency of training data for AI systems. Where Customer Content includes voice or likeness data of individuals, biometric data protections under GDPR Article 9 and Illinois BIPA (for US-based individuals) may apply. GOVERNANCE EXPOSURE: Medium. The scope of the license, specifically the inclusion of derivative works creation and use for service improvement, is broad relative to what many enterprise customers may expect from a SaaS vendor. The key question is whether 'improving and developing the Services' encompasses training AI models on customer-specific content, which the document does not resolve with specificity. JURISDICTION FLAGS: EU and UK customers processing personal data through the platform must ensure the license grant is consistent with their GDPR obligations, including data minimization and purpose limitation principles. Illinois BIPA creates heightened exposure for customers uploading voice or biometric data of Illinois residents. California customers should assess CCPA implications for any personal information included in uploaded content. CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers with proprietary training data, trade secrets, or personal data embedded in content should negotiate explicit limits on Synthesia's use of Customer Content for AI model training. The Data Processing Agreement referenced in the terms should be reviewed in parallel to understand the full scope of data use permissions. COMPLIANCE CONSIDERATIONS: Customers should conduct a content audit to identify what personal data or proprietary information is included in uploaded materials, and should review the Data Processing Agreement to confirm that AI model training use is either excluded or appropriately governed by data processing agreements meeting GDPR and applicable law requirements.
