Total Intelligence. Zero Exposure.

PII never reaches the LLM. The LLM never knows. Your user never sees a token.

01 · REQUEST

Request

Your app sends a prompt with a credit-card number, name, and IBAN.

02 · SHIELD

Shield

Semurg replaces sensitive values with [PII:CREDIT_CARD:1] tokens. Raw values never leave your account.

03 · REASON

Reason

OpenAI / Anthropic / Mistral processes the masked prompt — sees no PII, retains no PII.

04 · RESTORE

Restore

Semurg re-injects the original values into the response. Your user sees a complete answer.

100% Drop-in Compatible

Every provider you already use. None of the rewriting.

For Sovereign Teams

Stop worrying about what your team pastes into ChatGPT.

Route your organisation's AI traffic through the Semurg proxy. PII auto-shielded, every prompt audit-logged, every entity becomes a private searchable knowledge graph — automatically. Your provider bill stays with OpenAI / Anthropic. You pay Semurg $10/GB for the infrastructure.

Why Semurg

Built for sovereignty, priced for honesty.

🔐

Zero-knowledge by design

Your private key is generated in your browser. Semurg's servers see encrypted ciphertext only — never plaintext, never tokens, never embeddings.

⚡

CPU-supremacist stack

Built on Erlang/OTP + Rust NIFs (AVX2 + FMA). One binary, no Docker, no Kubernetes, no GPU lock-in. Runs on a $5/mo VM or a 96-core EPYC.

💸

$10/GB. Full stop.

One price for written, read, traversed, copied, sent. No tiers. No seat licences. No storage fees. Your knowledge graph sits on your hardware for free.
