Cypherz vs Private AI
Cypherz vs Private AI
Private AI is the self-hosted heavyweight — 50+ PII/PHI/PCI entity types across 49 languages, all running in the customer's environment so nothing leaves their VPC. Their PrivateGPT product specifically targets the ChatGPT use case. Cypherz can also self-host, but defaults to a hosted proxy so you can ship the integration without standing up infrastructure.

Common questions
Frequently asked.
Is Cypherz a direct replacement for Private AI?
For developer-shaped AI integrations — yes, and you'll likely ship faster. For enterprise-shaped data privacy vault deployments with central PII storage as the goal, Private AI remains the more mature pick.
Can I migrate from Private AI to Cypherz?
Yes. Tokenization mappings are project-scoped on both products; you can rotate keys and re-tokenize within a maintenance window. We've helped customers migrate in under a day.
Does Cypherz sign a BAA / DPA?
Yes, at Business and Enterprise tiers we sign BAAs (HIPAA) and DPAs (GDPR). Free and Pro tiers do not include signed agreements but use the same encryption and audit primitives.
Where is Cypherz hosted?
EU (Hetzner — Helsinki and Falkenstein) by default for the managed product. Self-host anywhere with one docker-compose command.
