Nextcloud Assistant: sovereignty score and 8 European alternatives

Nextcloud Assistant is the AI assistant in Nextcloud Hub, the collaboration platform from Nextcloud GmbH. Users can summarise, reword, translate and proofread text, ask questions about their own files (Context Chat), turn speech into text, generate images and have actions carried out in apps such as Calendar and Talk. The assistant does not run the AI tasks itself but relies on connected backends. The app is open source (AGPL-3.0) and runs inside your own Nextcloud installation.

Nextcloud GmbH is headquartered in Stuttgart, Germany. As a backend you can use local, self-hosted open-source language models, in which case data stays on your own server. It is also possible to connect external LLM services, such as Deutsche Telekom, IONOS, OVHcloud and plusserver, but also OpenAI or Gemini. If you choose a non-European service, your data leaves your own environment and that processing falls under the provider's jurisdiction. The choice of backend therefore determines the level of sovereignty.

Why digital sovereignty matters with Nextcloud Assistant

Nextcloud Assistant is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Nextcloud Assistant hosts data in EU, self-hosted (customer-controlled). 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.

Nextcloud Assistant is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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