Synthesia: sovereignty score and 8 European alternatives

Synthesia is an AI video platform for business. Teams create videos with AI avatars and voiceovers in more than 140 languages, run live avatar sessions, and build video features into their own products through an API. An assistant turns documents, PowerPoints or links into draft videos; translation, AI dubbing with lip sync, quizzes and analytics are also available. A personal avatar requires an on-camera consent recording. Videos are shared by link, embedded, or exported as SCORM packages. The service is a SaaS platform with roles, approval steps, SSO and SCIM.

Synthesia Limited is a British company headquartered in London and is privately held. On its website the company states that it is GDPR compliant and offers EU data residency, and lists certifications such as SOC 2 Type II and ISO 27001. It is not open source. For European organisations this means a supplier outside the EU, with an offered option to keep data in the EU.

Why digital sovereignty matters with Synthesia

Synthesia is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Data is hosted exclusively in the EU, so Synthesia scores best on data residency.

Synthesia is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Synthesia together with your other vendors and gives a total score, a heatmap and the main risk drivers.
