Zero-knowledge encryption

AI that actually respects your privacy

Multi-model AI platform with real client-side encryption. Unlike others who say "trust us" — we engineered it so we can't see your data.

Features

Everything you need, nothing we can see

Multi-modal AI with text, image, and code generation — all encrypted end-to-end before reaching our servers.

Text Generation

Chat with GPT-4o, Claude, DeepSeek, and more. Streaming responses, conversation history — all encrypted.

Image Generation

Create images with DALL-E 3 and Flux Pro. Gallery view, multiple sizes. Prompts encrypted at rest.

Code Assistant

Write, debug, and explain code with specialized models. Syntax highlighting, copy-to-clipboard.

Zero-Knowledge Vault

AES-256-GCM encryption with PBKDF2 key derivation. Your encryption key never leaves your browser.

OpenAI-Compatible API

Drop-in replacement for OpenAI's API. Use any client library — just change the base URL.

Streaming Responses

Real-time SSE streaming for all text models. See responses as they're generated, not after.

Privacy

Encryption you can verify

Not "we promise we don't look." Mathematically impossible for our servers to read your data.

1

You enter a password

Your password never leaves the browser. It's used to derive an encryption key locally.

2

PBKDF2 derives your key

600,000 iterations of SHA-256 transform your password into a 256-bit AES-GCM encryption key.

3

Everything is encrypted locally

Messages, titles, prompts — encrypted in your browser before any network request. We only store ciphertext.

4

AI sees plaintext transiently

Your message is decrypted client-side, sent to the AI provider for the response, then re-encrypted. Server memory only.

// What our server stores:
conversation.title = "kF8x2Q==:mN3vR7..."
message.content = "aB4yZ==:pQ9wT1..."

// What you see:
conversation.title = "Trip planning ideas"
message.content = "Plan a 5-day trip..."

// Decryption happens HERE
decrypt(vaultKey, ciphertext)
// ^ Your browser. Not our server.

API

OpenAI-compatible API

Drop-in replacement. Change one line and get encrypted AI with any client library.

POST
/api/v1/chat/completions
curl https://priv.ai/api/v1/chat/completions \
  -H "Authorization: Bearer priv-xxxx..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [
      {"role": "user", "content": "Hello, Priv!"}
