# SumizAI vs Standard Notes

Looking for a Standard Notes alternative? SumizAI and Standard Notes side by side: price, licence, platforms and what each one actually does.

## What Standard Notes is

Standard Notes is a secure note-taking app built around end-to-end encryption, giving users confidence that no one but them — including the company behind the app itself — has access to their note content. The app syncs without limits across every platform, works offline, and protects access with a strong passcode and biometric authentication, combining a privacy-first philosophy with practical everyday convenience.

Key features:

End-to-end encryption covers every note the moment it's saved, so even in the event of a server data leak, content stays unreadable without the user's key. Unlimited syncing across every platform — computer, phone, tablet — keeps the same notes everywhere, without the artificial device-count limits typical of cheaper competing plans. Offline access guarantees notes are always reachable, even with no internet connection, with automatic sync once it's back. Detailed organization through tags lets users categorize notes along multiple dimensions instead of being limited to a single folder hierarchy. Strong access protections — a passcode and biometrics — protect the app even if a device ends up in the wrong hands. Premium features extend the base plan with encrypted files, themes, advanced super note types, and hardware security key support for login.

Who it's for:

Standard Notes appeals to people treating note privacy as a priority — journalists protecting sources, lawyers working with confidential documents, activists in countries with limited freedom of speech, or simply users who don't trust cloud giants with their private thoughts. People who value openness and the ability to verify exactly how the encryption works appreciate the app's open-source nature, which allows independent code audits.

Use cases:

In practice, Standard Notes works well for keeping a personal journal, whose content is by definition sensitive and shouldn't fall into the wrong hands even in the event of a server breach. A lawyer storing notes from client meetings relies on the guarantee that content stays confidential even from the service provider itself. A journalist taking notes from conversations with sources requiring anonymity relies on encryption as an additional layer of protection. Someone syncing notes between a phone and a computer while traveling relies on unlimited syncing with no worry about device limits.

Pricing and business model:

Standard Notes offers a free plan with core note-taking and encryption functionality, and a paid subscription unlocks premium features — encrypted files, extra themes, advanced note types, and hardware key support. That model lets anyone use a secure, encrypted notebook for free, paying only for the convenience of extra features, not for security itself, which stays available at every subscription level.

Limitations and what to watch for:

End-to-end encryption means losing the master password means irreversibly losing access to notes — no one, not even the provider, can help recover encrypted data without the key. The interface, while solid, is more minimalist than some competing notes apps with extensive formatting or media embedded directly in a note. Some advanced features, like super note types, require a paid subscription, a limitation for free-plan users.

AI notes and the encrypted architecture:

Standard Notes has no built-in AI model integration, so preserving a ai notes entry from a conversation with an assistant requires manually copying a fragment and pasting it in as a new, encrypted note. That ai notes entry then benefits from the same end-to-end protection as the rest of the notebook — once saved, it's just as well protected as notes the user types directly, a real advantage for anyone wanting to keep sensitive fragments of AI conversations in the same secure place as the rest of their notes.

Trust through open code:

Standard Notes' open-source nature means encryption claims don't have to be taken on faith — independent security researchers regularly analyze the app's code, checking whether the encryption actually works the way the maker claims. That's a rare approach among commercial notebooks, many of which remain closed, unverifiable code, forcing users to blindly trust marketing claims about security.

Zero-knowledge as an architectural foundation:

The zero-knowledge model Standard Notes is built on means the company's servers store only encrypted data, unreadable even by the company's own employees or in response to a law enforcement legal request. That's a fundamental difference from notebooks that encrypt data only in transit but store it in readable form server-side — Standard Notes eliminates that risk vector from the outset.

What's worth checking before choosing:

Before fully switching to Standard Notes, it's worth settling on a secure way to store the master password — in a password manager, for instance — since losing it means permanently losing access to every encrypted note, with no way for support to recover it.

A tradeoff between security and convenience:

Some convenient features common in competing notebooks — server-side full-text search for faster results, for instance — are harder to implement in a zero-knowledge architecture where the server can't see note content. Standard Notes solves this with local, on-device search, somewhat slower with very large note collections, but requiring no compromise on privacy. For most users the speed difference is unnoticeable, but it's worth knowing about that tradeoff. It's worth accepting that consciously as the price of real privacy, rather than treating it as a flaw stemming from worse engineering.

Bottom line:

Standard Notes is a solid, open, encrypted notebook for people who put privacy ahead of extensive features. Anyone who wants ai notes from AI conversations to land there automatically, already encrypted, without manual copying, should consider a tool that generates such files directly from the conversation.

Comparison with SumizAI:

Standard Notes and SumizAI agree on the importance of user control over their own data, but differ in approach. Standard Notes protects notes with end-to-end encryption on the provider's servers, with syncing across devices. SumizAI keeps ai notes as plain Markdown files locally, in a vault the user owns, generated directly from a conversation with an AI model. Anyone who prioritizes encryption and cloud sync will pick Standard Notes; anyone who wants ai notes from AI to land straight in local, portable files with no third-party server in between will find SumizAI the better-fitting tool.

## What SumizAI is

A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.

A vault is a directory holding `base.md`, a generated table of contents up to six levels deep, and a `notes/` folder with one `.md` file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.

The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

## Where they differ

- AlternativeTo's description of Standard Notes does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them.
- Standard Notes is open source (AGPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Standard Notes. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running.
- Standard Notes is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
- AlternativeTo's description of Standard Notes does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard `.md` files to a folder you picked, and an unpaid account can still export all of them.
- Standard Notes advertises encryption. SumizAI answers the same worry a different way: on the desktop the notes never leave your disk, and the material a question sends to the model is capped at the table of contents plus at most five notes — and the app shows you which five it used.
- Standard Notes can be self-hosted. SumizAI has nothing to host on the desktop — the vault is a folder on your machine — and if you want the model on your own hardware too, a local Ollama is one of the seven providers it speaks to.
