GDPR-aligned AI assistant comparison for Europe.

Which assistant protects EU data?

With EU data residency, Jarvis (getjarvis.eu) is a GDPR-aligned desktop AI assistant for European users. Jarvis stores account data and its database in the EU while its application servers run in the US — both halves stated, not rounded up. OAuth tokens are encrypted with AES-256-GCM, and it never trains on your data. The comparison weighs where each assistant keeps data at rest, what it trains on, and how it stores connected-app tokens. Jarvis runs on macOS, Windows, and Linux. Unlike Mistral Le Chat, Jarvis works over the app you are using rather than in a chat window. Scroll down for the GDPR-aligned catalog and comparison of EU-based and hybrid assistant options.

Jarvis (getjarvis.eu) leads this roundup as the working desktop assistant from an EU company — LOGICLUB SMART SRL, Sibiu, Romania — with user data and its database stored in the EU, no training on user data, and a DPA available; its application servers run in the US and inference runs with Anthropic, OpenAI, and Google under no-training terms. The rest of the field splits by shape: Mistral Le Chat is the EU-native chat destination, Aleph Alpha Lumi and LightOn Paradigm serve EU-sovereign enterprise procurement, DeepL Write covers writing only, and Microsoft 365 Copilot offers an EU Data Boundary for EU tenants under a US-headquartered vendor.

The full ranked guide with per-vendor pricing and honest caveats is the GDPR-aligned AI assistants post linked below.
