Everything you need.
Nothing you don’t.

A Notion-level workspace that runs entirely on your machine — for free.

Cloud collaboration is an opt-in upgrade, not a requirement.

Rich block editor

Headings, checklists, callouts, code blocks, multi-column layouts, inline math, diagrams, images, audio, video, bookmarks — all with drag-and-drop reordering and real-time collaboration cursors.

/slash commands drag & drop bubble menu block menu

Rich text outliner

Nest any block inside another to build hierarchical outlines. Collapse a parent block to hide its children and keep long documents navigable. Indent with Tab, outdent with Shift+Tab — structure emerges naturally as you write.

Works offline, always

The desktop app runs a full SQLite backend locally — no server, no account, no network required. Open, edit, and create pages anywhere. Changes sync automatically when you reconnect.

Markdown interoperability

Export any page to clean Markdown at any time and open it in any text editor. Datatable blocks export as CSV. Your data is never locked in a proprietary format.

Inline comments & threads

Select any text and start a comment thread. Reply, resolve, or re-open — all visible live to collaborators. Threads are anchored to their text position and sorted by where they appear in the document.

Inline databases

Embed sortable, filterable, paginated tables inside any page. 12+ column types including text, numbers, dates, relations, rollups, checkboxes, select, and media attachments.

Calendar, Tasks & Tags

A calendar panel gives a monthly overview of all dated pages. A task panel surfaces every checkbox across your workspace so nothing falls through the cracks. Tags are inline — label ideas within a page, not just the page itself — and filter across your entire knowledge base.

Multi-device sync

Your notes stay in sync across all your devices — desktop and the web app now, mobile coming soon — via zero-knowledge encrypted cloud sync. Changes made offline are merged automatically when you reconnect — no conflicts, no data loss.

Real-time collaboration

Invite teammates to your workspace. See each other’s cursors, edits, and comments live — powered by Yjs CRDTs and the Hocuspocus protocol with end-to-end encryption.

Workspace sharing

Share an entire workspace with teammates or guests. Fine-grained permissions let you control who can view, comment, or edit — with end-to-end encryption maintained throughout.

Total ownership & privacy

Your data always lives on your device — archive documents for long-term storage, export to Markdown at any time, and never worry about vendor lock-in. Your content is encrypted client-side before it ever touches a network: no analytics, no telemetry, no ad profiles. Your workspace outlives any company.

Workspace focus mode

Activate only the workspaces relevant right now — inactive ones disappear from the sidebar and search results. Keep work, personal projects, and client spaces cleanly separated without ever archiving or deleting anything.

Full power.
Full privacy.

Most knowledge tools make you choose between features and privacy. Sovernote is different.

Your sovereign, permanent workspace

Your workspace should outlive any company. Sovernote gives you long‑term ownership, local export, and a future‑proof data model — because your knowledge deserves permanence.


For synchronization and collaboration, Sovernote uses client-side key derivation so your encryption keys never leave your device. Even if the cloud server were compromised, your documents would be unreadable ciphertext.

Anti-exploitation privacy. The company structurally cannot turn your data into a product — no behavioural profiling, no monetisation of what you write, no AI training pipelines. End-to-end encryption makes this a cryptographic fact rather than a policy promise. Local data is stored as plain SQLite so you can always open, export, and own it directly.

01
Deterministic keypair

Your password is run through Argon2id locally to derive a 32-byte seed, then two keypairs — Ed25519 for authentication and X25519 for key agreement. No password ever leaves your device.

02
Challenge-response login

The server issues a random nonce. Your device signs it with your private Ed25519 key. The server verifies the signature. Done — no password transmission, no password hash, no password storage.

03
Permanent, pseudonymous username

Your username acts as the Argon2id salt. It’s immutable — changing it would permanently alter your keypair. Privacy-conscious users can register with a handle instead of their email.

Key derivation (client only)
// 1. Derive a stable user_id from username
user_id = UUID(SHA-256(normalise(username)))

// 2. Derive keypair from password + salt (client-only)
seed = Argon2id(password, salt: user_id)
ed25519_keypair = Ed25519.fromSeed(seed)
x25519_keypair  = X25519.fromSeed(seed)

// 3. Authenticate via challenge-response
nonce = GET /api/auth/challenge
token = POST /api/auth/login({
  username,
  signature: Ed25519.sign(nonce, privateKey)
})

// The server stores ONLY the public key.
// Your password never leaves this device.

Common questions

Can I really use Sovernote without ever creating an account?

Yes. The desktop app runs a full local SQLite backend — no server, no account, no network required. You can install and use it entirely offline. An account is only required if you want multi-device sync or real-time collaboration.

How does zero-knowledge encryption work?

Your encryption keys are derived locally from your username and password using Argon2id. They never leave your device. When syncing to the cloud, your documents are encrypted before they leave your machine. The server stores only encrypted blobs and your public key — it has no way to read your content.

What happens if I forget my password?

Your password is only needed for cloud sync and collaboration — it is the key that unlocks your encrypted identity for multi-device access. Since it is derived deterministically into a keypair, there is no server-side reset. We recommend keeping a secure backup in a password manager.

Regardless of plan, your data is always stored on your device and is never exclusively held by our servers. If you forget your cloud password you will lose access to sync and real-time collaboration, but your local copy of all your notes and databases remains fully intact and accessible. At most, you would re-register with a new password and re-import your local data — you will never lose your content.

Is Sovernote open source?

The server will be open source and self-hostable — you will be able to run the full sync and collaboration backend on your own infrastructure if you prefer. We believe transparency is essential for a privacy-first product: you should be able to audit the server code, verify the encryption claims, and never be forced to depend on our hosted service.

How do synchronization and collaboration work if the server can’t read my data?

Conflict-free Replicated Data Types (CRDTs) — specifically the Yjs library — let multiple clients merge edits without a central coordinator that understands the content. The server relays encrypted Yjs update blobs between peers. It never needs to parse or understand the content to provide convergence.

Collaboration is secured with per-workspace client-side key pairs. Keys are exchanged directly between clients as encrypted envelopes, so the server never has access to plaintext key material — enabling end-to-end encrypted, zero-knowledge, real-time collaboration.

What platforms does Sovernote support?

Sovernote is available as a desktop app (macOS, Windows) and a web app for paid subscribers. A mobile app (iOS, Android — coming soon) is in development. All apps are built on the same local-first, privacy-first architecture. The web app doesn’t store data locally, so it can be used on untrusted machines.

Can I export my data?

Yes. Pages can be exported to clean Markdown files at any time. Datatable blocks export as CSV. You own your data and can move it any time — no lock-in.

Start writing. No sign-up required.

Download the desktop app and get started in under a minute. Your content stays on your machine, private by default.
