Write the way you already write. Own everything you create.
A note-taking app for Mac, Windows, Linux, and Android. Plain markdown files on your disk, end-to-end encrypted sync between your devices. Yours to keep, forever.
Built around four ideas.
Just write.
Bold, italic, lists, tables, tasks. Keyboard shortcuts you already know. No markdown to memorize, no syntax to learn. Start with a single note today; let it grow into whatever you need.
Lives on your computer.
Your notes are real files on your disk. Open them, back them up, take them with you. The app works offline. Always.
Private by design.
End-to-end encrypted sync between your devices. Your password never leaves your machine. Not even we can read your notes.
Built on open formats.
Under the hood, your notes are markdown: portable, future-proof, and ready for the AI tools you'll want tomorrow. Without locking you into anyone's ecosystem today.
Write it together. Still nobody else can read it.
Share a folder or a single note. Everyone works in the same notes, in their own vault, on desktop and phone. End-to-end encrypted to exactly the people you invited, and nobody else.
- Invite by email. Editors write, viewers read. Remove someone and their access ends instantly.
- Write at the same time. Edits merge into one note, never into duplicate copies to untangle.
- The server still stores unreadable bytes. Sharing hands keys to people, never to us.
Needs Jotura Sync on both sides, yours and theirs. £4 a month each.
Both edits kept, in one note. No copies, no choosing.
Agents that get smarter about you.
Jotura ships a command-line companion that gives the AI tools you already use (Claude Code, Codex, Gemini, Copilot) a real memory. They start every session knowing your decisions, your conventions, and your loose ends. They learn as you work. And everything they remember is a plain note in your vault: yours to read, edit, or delete.
- Self-improving out of the box. One install command wires the memory loop into your agent.
- One shared memory across every agent you use. Switch tools, keep everything they learned.
- Safety unchanged: hash-checked edits mean an agent can never quietly overwrite your work.

The small things you notice in the first five minutes.
Tables you click, not count.
A real table editor inside a markdown note: add rows, edit cells, resize columns by dragging. Checklists, headings, and quotes format themselves as you type. Underneath, it's all still plain markdown, saved byte-for-byte.
Every checkbox, rolled up.
Any checkbox in any note becomes a task. The tasks panel gathers them from across your vault, dated ones from your daily notes and the rest grouped by where they live. One click takes you to the note that owns it.
Open to where you left off.
The dashboard greets you with your recent notes, today's daily note one keystroke away, and search a keystroke beyond that. No home-screen ceremony. You're two seconds from writing.

Two devices. One vault. Only you can read it.
Jot something on your laptop at lunch and pick it up on your desktop at home, seconds later. Your notes are locked on your device before they ever leave it, so the server passing them between your machines only ever sees encrypted data it cannot read, never your words.
- Your password is the only key, and it never leaves your device.
- A recovery phrase keeps you from ever being locked out of your own notes.
- Change a note in two places at once and both versions are kept. Nothing is silently overwritten.
Everything you'd want, nothing you wouldn't.
The features that matter for everyday writing, and none of the clutter that gets in the way of it.
Write naturally.
Headings, bold, lists, quotes, checklists, real tables. The formatting appears as you type. There's no markup to memorize, and a flip to source mode whenever you want the raw markdown.
Find anything in a second.
Jump to a note by its title, or by a phrase you half-remember from somewhere inside it. It stays instant whether you have a hundred notes or ten thousand.
Tables, tasks, and daily notes.
Proper tables you click to edit. Checkboxes that roll up across your vault so you see what's left. A dated note for every day, one keystroke away.
Organize it your way.
A vault is just a folder of folders. Drag notes between them, keep several open in tabs. No rigid structure to fit into, no database to learn.
Plain files, private sync.
Your notes are ordinary markdown files on your disk. Open them with anything, forever. Sync encrypts them on your device before upload, with a password that never leaves your machine.
Works on every device.
Mac, Windows, and Linux, with the same vault and notes on each. Move between computers as often as you like. Nothing to convert, nothing to re-import.
Drop in a document. Find it later.
PDFs, Word docs, spreadsheets: drop them into your vault and they live right alongside your notes. Jotura builds a searchable markdown mirror of each one automatically, so you can find a document by what's inside it, not just its filename.
- Add by drag-and-drop, paste, the command line, or an optional OS folder you drop files into.
- Open any document in its native app. It's a real file, so your edits save in place.
- The converter ships inside the app and runs sandboxed with no network. Nothing to install, works offline.
- Code, SQL, CSV, and HTML files open right in the app: a real editor for text, a safe rendered view for HTML.
Roadmap.
Version history, sharing, semantic search, documents, tables, and daily notes have shipped. Here's what's next.
Self-improving agents
shippedYour AI tools share one durable, private memory: decisions, conventions, follow-ups. Plus a vault home for every tool's config, synced to all your machines.
Version history
shippedEvery synced note keeps its full history: every version, who wrote it, and one-click restore, on any device. Kept for three years, encrypted like everything else.
Semantic search
shippedSearch by what you mean, not just the words you wrote. A small AI model runs entirely on your machine, GPU-accelerated when you have one, so meaning-based search costs nothing in privacy.
Documents
shippedDrop in PDFs, Word docs, and spreadsheets. Real files right alongside your notes, mirrored to searchable markdown, editable in their native apps.
Tables that behave
shippedInsert real tables, click to edit, drag to resize. Never count pipes and dashes again.
Task lists
shippedCheckboxes you can actually use. Track what you're doing, see what's done, roll up across notes.
Daily notes
shippedOne note per day, auto-dated, one keystroke away. Journal, work log, capture-and-process, however you use it.
Android
shippedThe same Rust core as desktop: same vault, same keys, same encrypted sync.
Sharing
shippedShare a folder or a single note, encrypted to the people you invite. The server still can't read it. Needs Jotura Sync on both sides.
AI you control
roadmapBring-your-own-key writing assistance. Your notes stay on your machine; AI only sees what you choose to send.
