  • Markdown editor built around developer workflows
  • Encrypted sync across devices
  • End-to-end encrypted on device with XChaCha20-Poly1305 and Argon2, so the service holds no readable data
  • The full client codebase is published, which makes the privacy claim auditable
  • Closed source commercial product
