What Cybrmail is
Cybrmail combines encrypted email, an AI brain, wallet identity and a U.S. postal mailbox in one inbox. The maker says messages are encrypted on the device with libsodium XChaCha20-Poly1305 and that decryption keys stay there. AI tools include a knowledge graph, promise tracking, decision logging, smart replies and voice mode. Depending on settings and availability, AI requests may go to Apple Foundation Models, a user’s Ollama URL, Groq, OpenRouter or another user-selected BYOK provider. Wallet sign-in supports WalletConnect and Sign-In with Ethereum; wallet-to-wallet encrypted messages use XMTP. Apple and password sign-in are also listed. The postal service provides a U.S. street address and can photograph and OCR incoming physical mail. It requires USPS Form 1583, and forwarding charges apply per piece based on the plan. Users can export email, calendar and notes in mbox, iCal and markdown formats. Cybrmail has a free plan. Its homepage says iOS is available, describes Android as in review and links to a browser app.
