What Cybrmail is
Cybrmail combines encrypted email, an AI brain, wallet identity, and a US postal mailbox in one inbox. The maker says messages are encrypted on the device with libsodium XChaCha20-Poly1305 and that decryption keys stay there. Its AI features include a knowledge graph, promise tracking, decision logging, smart replies, and voice mode. Depending on settings and availability, AI requests may be routed to Apple Foundation Models, a user’s Ollama URL, Groq, OpenRouter, or a provider chosen through BYOK. Wallet sign-in supports WalletConnect and Sign-In with Ethereum, while wallet-to-wallet encrypted messages use XMTP; Apple and password sign-in are also listed. The postal service supplies a US street address and can photograph and OCR incoming physical mail, but using it requires USPS Form 1583, and forwarding charges apply per piece according to the plan. Users can export email, calendar, and notes in mbox, iCal, and markdown formats. Cybrmail has a free plan at no cost. Its homepage says iOS is available, describes Android as in review, and links to a browser app.
