MistralBuilt for privacy from day one
No black-box models. No silent data harvesting. Just transparent open-weight AI
running through a German-hosted, GDPR-by-design pipeline.
Open-Weight Models Only
Only transparent, open-weight models. No closed APIs, no hidden data policies. You always know what's running your AI.
End-to-End Encrypted
Messages are encrypted in transit with industry-standard ciphers. Hover the lock — that's your data, scrambled.
Made in Germany · GDPR by Design
Operated from Germany under EU law. ULD oversight, Kleinunternehmerregelung, no transatlantic data drift.
No Tracking, No Profiling
No ads, no analytics graveyard, no behavioral profiling. A tool, not a marketing funnel.
