Confidential AI
for legal tech.
Build AI features with frontier models —
while your customers' privileged files stay encrypted end-to-end.
Why confidential AI
Legal Tech
Privilege doesn't survive
a third party reading the file.
Professional secrecy is not negotiable
Your customers are bound by professional secrecy — in Germany, breaching it is a criminal offense under § 203 StGB. A legal AI product that sends privileged content to a public AI service is a deal-breaker for law firms and legal departments. Privatemode processes prompts inside hardware-isolated environments no one can look into, so the content is never disclosed to anyone.
Even you can't see your customers' data
Prompts and documents are encrypted on the user's device and stay encrypted during processing. Neither you as the vendor nor Privatemode or the cloud provider can access them — a sales argument you can verify, not just promise.
Frontier quality for demanding text work
Legal drafting and review need the best models available. Privatemode serves leading open-weight LLMs as a managed service through an OpenAI-compatible API — no on-prem hardware, no maintenance.

Frequently asked questions from legal tech providers
Privatemode is designed so that mandate content is never disclosed to anyone — not to you as the vendor, not to Privatemode, not to the infrastructure provider. Prompts are encrypted on the user's device and only decrypted inside hardware-isolated confidential-computing environments, which is a fundamentally stronger position than services that process plaintext under a contract. Your customers' own professional-law assessment still applies.
