Notesnook Review 2026: Is It Really Private, and Is It Worth It?

What Notesnook actually is

Notesnook is a privacy-first note-taking app built by Streetwriters. The pitch is simple: everything you write is end-to-end encrypted on your device before it syncs, so the company hosting your notes cannot read them. It competes less with Notion or Google Keep and more with the small club of encrypted note apps, chiefly Standard Notes.

What makes this Notesnook review different from the ones ranking above it is timing and perspective. Most reviews you will find quote pricing that is one or two restructures out of date, and most were written by generalist tech writers. I run a note app of my own, so I care about the architecture underneath: the encryption scheme, the sync model, and where the paywalls actually fall. Below is the current picture, verified against the official pages in July 2026.

Is Notesnook really private and safe?

Zero-knowledge means the encryption keys are derived from your password and never handed to the server, so Notesnook staff physically cannot decrypt your notes. That is the same threat model Signal uses for messages. It applies on every plan, including the free one, which is not always true of "encrypted" note apps that reserve encryption for paying users.

The gap worth knowing about is verification. Standard Notes has commissioned independent security audits from outside firms. Notesnook has not done so publicly as of this writing. Its answer is transparency instead: the full source is open, so anyone can inspect the cryptography. That is meaningful, but an open codebase and a signed audit report are not the same assurance. If you are protecting notes where being wrong is unacceptable, weigh that.

Is Notesnook free, and what do you lose?

For a plain-text note-taker, 50MB per month is a lot of writing. Where free users hit the ceiling is media: images are compressed, and the 10MB file cap rules out attaching large PDFs or high-resolution photos. The 7-color and 50-notebook limits also feel tight if you organize visually. None of that touches your ability to actually take, encrypt, and sync notes, which is the point of the app.

Compared to other free note apps, the standout is that Notesnook gives you rich text editing for free. Standard Notes historically charged for anything beyond plain text. So the free plan here is not a crippled demo; it is a usable daily driver for most people.

Notesnook pricing in 2026 (current 4-tier table)

Here is the current matrix, with each plan linked to the official pricing page.

A few practical notes. Pro is the tier most people who outgrow free will want, because it unlocks unlimited colors, tags, notebooks, reminders, and note versions along with 10GB of monthly storage. There is also a 5-year Pro option at 344.99 dollars (5.75 dollars per month) and a 5-year Believer at 459.99 dollars for people who want to lock in a price. Notesnook also offers an education discount by application if you are a student.

Believer is essentially a support tier: you pay more mainly to fund the project and get larger storage, not a materially different feature set from Pro. That is a fair, honest way to structure it, and worth calling out because the name alone does not make that obvious.

Features that stand out

Beyond encryption, Notesnook is a real writing app. Per the official feature list, it runs on Windows, macOS, Linux, the web, iOS, and Android, and includes:

• A rich editor with markdown, tables, task lists, code blocks, and math.
• Bidirectional note linking, so you can connect related notes both ways.
• Vault, a password-protected space for your most sensitive notes on top of the base encryption.
• Monographs, encrypted shareable links for publishing a note without exposing your account.
• A web clipper for saving pages, plus reminders.

On the open-source side, the repository is GPL-3.0 licensed, has around 14,300 GitHub stars, and is roughly 85% TypeScript across web, desktop (Electron), and mobile (React Native) clients. Crucially, the sync server is self-hostable, so you are not locked into Streetwriters' infrastructure if you would rather run your own. That combination, easy hosted sync for normal users plus self-hosting for the technical, is rarer than it sounds.

Notesnook vs Standard Notes vs Obsidian

A reviewer who switched from Standard Notes to Notesnook summed up the tradeoff well: Notesnook gives you rich text for free where Standard Notes charges for it, but custom note colors sit behind Notesnook's Pro plan, and Notesnook lacks the third-party audits Standard Notes has done. That is the honest scorecard.

Obsidian is a different category. If you want a local vault, a visible graph of links, and a huge plugin ecosystem, read our Obsidian review or the broader Obsidian alternatives roundup. If you are coming from Evernote and mainly want encryption plus sync, our Evernote alternatives guide puts Notesnook in context. Linux users should also see our Linux note-taking app comparison, where Notesnook rates highly.

Who should NOT pick Notesnook

An honest review has to say who should walk away. Skip Notesnook if:

• You want native AI features. Notesnook has no built-in AI writing, summarizing, or search. It is a privacy tool, not an AI note-taker. If AI-assisted organizing is the whole reason you are switching apps, this is not it.
• You need an audited encrypted app on record. Until a third-party audit is published, security-sensitive users may prefer Standard Notes.
• You want a knowledge graph. Notesnook has bidirectional links but not Obsidian's local graph model or plugin depth.
• You dislike paywalled basics. Custom colors, generous limits, and larger attachments require a paid plan. That is reasonable, but if you want everything unlimited for free, expect friction.

If any of those is a dealbreaker, a second-brain style app or a different note-taking pick may fit better. If encryption is your top priority, though, none of these is a reason to avoid it.

Verdict: is Notesnook worth it?

Yes, for the right person. Notesnook delivers the thing it promises: real, zero-knowledge, end-to-end encryption on every plan, an open codebase you can inspect or self-host, a usable free tier, and a full editor across every platform. The current pricing is fair, and starting free costs you nothing but a few limits.

It is worth paying for Pro if you attach media, want unlimited organization, or simply want to support open-source privacy software. It is not worth it if you came looking for AI or a graph, because that is not what Notesnook is trying to be. Judged as a privacy-first note app in 2026, it is one of the best, held back only by the missing third-party audit. If that gap closes, the recommendation gets stronger.

FAQ

Is Notesnook really private?

Yes. Notesnook is a zero-knowledge, end-to-end encrypted note app that encrypts your data on your device before it ever reaches the cloud, using XChaCha20-Poly1305 for encryption and Argon2 for key derivation. The company cannot read your notes because the keys never leave your device. The main caveat for 2026 is that Notesnook has not yet published a third-party security audit, so you are trusting its open code rather than an independent firm's sign-off.

Is Notesnook free to use?

Yes, Notesnook has a genuinely free plan that costs zero dollars and includes end-to-end encryption, sync across unlimited devices, and rich text editing. The free tier caps you at 50MB of monthly storage, 10MB per file, 7 note colors, 50 tags, 50 notebooks, and 10 reminders. Paid plans start at 22.99 dollars per year and raise those limits.

Is Notesnook open source?

Yes. The Notesnook clients and sync server are open source under the GPL-3.0 license, published by Streetwriters on GitHub with about 14,300 stars. The code is primarily TypeScript and covers the web, desktop, and mobile apps plus a web clipper. Because the sync server is also open, technically minded users can self-host it instead of using the hosted service.

Does Notesnook have end-to-end encryption?

Yes, on every plan including free. Notesnook encrypts your notes on the device with XChaCha20-Poly1305 and derives keys with Argon2, then stores the data encrypted on device, in transit, and in the cloud. This is real zero-knowledge encryption, meaning even Notesnook staff cannot decrypt your content without your password.

How secure is Standard Notes compared to Notesnook?

Both use strong end-to-end encryption and are open source, so on core cryptography they are close. The practical difference is that Standard Notes has completed independent third-party security audits, while Notesnook has not yet. Notesnook, however, gives you rich text editing for free, whereas Standard Notes has historically reserved advanced editors for paid users.

How good is Notesnook?

Notesnook is one of the strongest privacy-first note apps available in 2026, with real end-to-end encryption, a permissive free tier, cross-platform sync without self-hosting, and a full-featured editor. It is best for people who prioritize privacy and control over AI features or knowledge graphs. It is a weaker fit if you want built-in AI, a native local graph, or an independent audit on record.
