AssemblyAI: sovereignty score and 8 European alternatives

AssemblyAI provides application programming interfaces for speech-to-text, real-time transcription and audio intelligence. Developers use them to add features such as speaker labels, summaries, content moderation and removal of personal data from transcripts to meeting tools, call-centre software and voice agents. The service is delivered as an API; the documentation does not describe a self-hosted or on-premises option.

AssemblyAI, Inc. is a US company, and its default endpoint processes requests in the United States. The privacy policy states that the services are predominantly hosted and operated in the US. For European customers, a dedicated EU endpoint (api.eu.assemblyai.com) is documented as keeping audio and transcription data entirely within the European Union, and the privacy policy refers to a data processing addendum. EU routing is set per product and should be checked. Because the company is subject to US law, possible access by US authorities, for example under the CLOUD Act, remains a point for European organisations to weigh.

Why digital sovereignty matters with AssemblyAI

AssemblyAI is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

AssemblyAI hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

AssemblyAI 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 AssemblyAI together with your other vendors and gives a total score, a heatmap and the main risk drivers.
