Cybrmail · New York, New York, USA
What it 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, keeping decryption keys there. AI tools include a knowledge graph, promise tracking, decision logging, smart replies, and voice mode. Depending on settings and availability, requests may go to Apple Foundation Models, a user’s Ollama URL, Groq, OpenRouter, or another selected BYOK provider. Wallet sign-in supports WalletConnect and Sign-In with Ethereum, while wallet-to-wallet encrypted messages use XMTP. Apple, Ethereum wallet, and password sign-ins are listed. The postal service supplies a US street address and can photograph and OCR incoming mail, but USPS Form 1583 is required and forwarding charges apply per piece. Users can export email, calendar, and notes in mbox, iCal, and markdown. Cybrmail lists a free plan at no cost. Its homepage says iOS is available, Android is in review, and a browser app is linked.
