Draw, diagram, and brainstorm together in real time. Your designs are encrypted on your device before they ever leave your browser. The server sees only ciphertext.
Everything you need for collaborative design, without compromising on security.
X25519 ECDH + AES-256-GCM. Your drawings are encrypted before leaving the browser. The server holds only ciphertext.
Full-featured infinite canvas powered by Excalidraw. Sketch diagrams, wireframes, flowcharts, and more.
Work together with your team in real time via Yjs and WebSockets. See each other's cursors and changes instantly.
Get intelligent reviews of your designs. Supports Ollama (local), OpenAI, and Anthropic. API keys never leave your browser.
Electron wrapper for CORS-free local Ollama access. Code-signed and notarized for macOS.
6 one-time recovery codes protect you from a forgotten passcode. Your private key is never stored in plaintext.
DrawPro uses an ECIES encryption scheme with X25519 key exchange and AES-256-GCM authenticated encryption. Every piece of content — drawings, names, metadata — is encrypted on your device.
Your private key is wrapped with a passcode you choose, derived via Argon2id (128 MB memory cost). Even if the database is stolen, your data is useless without the passcode.
The server performs encryption using only your public key and can never reverse the process. Decryption happens entirely in your browser.
