Your Private Digital notebook

Plain markdown. Open format. No vendor lock-in — ever. All processing happens on your device: semantic search understands concepts, OCR makes images searchable, everything works offline. When you sync, your data travels only as unreadable ciphertext — end-to-end encrypted, readable by no one but you. Organization optional. Finding anything — even in chaos — is not.

Why This Exists

This app exists because of frustration. Real frustration.

  • Need to access notes everywhere — not just on one machine.
  • Want it to work out of the box. No installing apps, no setup.
  • Need personal notes accessible even behind corporate networks.
  • Tired of editors mangling bidirectional text. Here it renders correctly. By default.
  • Don't want to think about privacy. Out-of-box E2E encryption for sync
  • Obsessed with plain text and open formats — because that's the only real foundation. No vendor lock-in. No proprietary formats. Your notes are just files — readable by any text editor, portable, exportable. Yours. Forever.
  • Prefer calm, distraction-free writing. And seriously — who decided a blinking cursor was good UX? Not here. Not by default.

Our Philosophy

� Complete Privacy

Your notes are stored as plain markdown documents on your local device. When sync is enabled (strongly recommended), your notes are encrypted end to end before they leave your device, so the server only ever sees unreadable ciphertext. All processing happens locally—OCR, semantic search, everything. We will never have a feature that sends your data to the cloud unencrypted. No server sees your notes, ever. No cloud lock-in, no proprietary formats, absolute privacy. Your knowledge belongs to you.

🔍 Search First, Organize Never (If You Want)

We're all lazy. We jot things down, paste snippets, dump thoughts—then never organize them. And that's okay. With semantic search, you don't need to remember exact keywords. With OCR, even your screenshots become searchable. Find what you need in the chaos, not despite it. Organization is optional; finding information is not.

⚡ Frictionless & Fast

Note-taking, retrieval, searching—everything should be instant and effortless. No barriers, no hassle. Just open your browser and start writing. Built for speed with local-first architecture, instant search, and a clean, distraction-free interface. Pick up where you left off from any device. Find information in the clutter. Write in plain markdown, no learning curve required.
