# SumizAI vs Mimiri Notes

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

## What Mimiri Notes is

Mimiri Notes is a Swiss notepad built around one priority feature — security. Notes are encrypted with AES-GCM-256 before they ever leave the user's device, so even when synced through the provider's cloud, the content stays unreadable to anyone but the key's owner. This approach sets Mimiri apart from many popular note apps that do encrypt data in transit but store the content server-side in a form the service operator can read.

Key features:

Notes in Mimiri are organized in a tree structure, letting users build a hierarchy of folders and subfolders similar to a file system, instead of a flat list of unrelated entries. Change history tracks successive versions of every note, so accidentally deleting an important passage does not mean losing it for good — you can roll back to an earlier version. Collaboration options let selected notes be shared with other users without losing end-to-end encryption, which is rare among privacy-focused tools. The app is available on all major desktop and mobile platforms, plus a self-hosted edition for people who want full control over the infrastructure storing the encrypted data, and access through extensions for popular browsers.

Who it's for:

Mimiri reaches people for whom note confidentiality is a priority above convenience — lawyers, journalists, consultants working with sensitive client data, and anyone who simply does not want their note content readable by the service provider. The GPL-2.0 open-source code further attracts technical users who want to verify for themselves exactly how the encryption works rather than take marketing claims on faith.

Use cases:

In practice, Mimiri works well for keeping notes from legal or medical consultations, where confidentiality is a professional requirement, not just a preference. Investigative journalists store source notes in it that need special protection against unauthorized access. People running a self-hosted instance gain full control over where the encrypted data physically lives, which can matter for compliance with local data protection regulations.

Pricing and business model:

Mimiri runs on a freemium model, pairing a free open-source core under the GPL-2.0 licence with paid options for extra cloud storage or technical support. Users who want to avoid any fees entirely can self-host their own instance, which is fully supported by the developers rather than treated as a workaround of the business model.

Limitations and what to watch for:

End-to-end encryption means losing your password or encryption key can permanently lock you out of your notes — unlike services without end-to-end encryption, the provider cannot help restore access because it has no visibility into the content either. Self-hosting requires basic technical knowledge and maintaining your own infrastructure, which can be a barrier for less technical users. The community around the project is smaller than around large commercial notes apps, which translates into fewer ready-made integrations with other tools.

What's worth checking before choosing:

Before storing important notes in Mimiri, make sure to set up a secure backup procedure for your password or encryption key — losing it is irreversible. It's also worth assessing whether your work actually requires end-to-end encryption or whether the standard transit encryption offered by most popular note apps is enough, since Mimiri's extra security comes with extra responsibility on the user's side.

Trust model and verifiability:

Mimiri's open-source code under the GPL-2.0 licence carries concrete practical meaning beyond a marketing claim — anyone with the technical knowledge can review the AES-GCM-256 encryption implementation and verify for themselves that it actually works as the developers claim, rather than taking it on faith. That sets Mimiri apart from closed note apps that declare security without allowing independent verification. People keeping sensitive ai notes from professional consultations appreciate this transparency as an extra layer of trust beyond the end-to-end encryption claim itself. Mimiri's folder-tree structure also means large collections of ai notes can be organized hierarchically much like files on a disk, instead of a flat list that becomes hard to navigate over time.

Encrypted ai notes:

For people who would like their ai notes from AI model conversations to carry the same end-to-end encryption level as the rest of Mimiri's content, the app has no direct integration with any model provider — the conversation content has to be pasted in manually as a new note. The upside is that once pasted, those ai notes get the full benefit of AES-GCM-256 encryption just like every other note in the tree, which for sensitive topics can matter more than the convenience of automatic saving.

Bottom line:

Mimiri wins where end-to-end encryption is a non-negotiable requirement, at the cost of automatic-save convenience — ai notes from AI conversations have to be pasted in there manually, with no ready-made integration. For ai notes that don't need quite that strict a level of security, a simpler tool that saves conversations as these notes automatically can be a more practical everyday choice than the extra step of copying into an encrypted archive.

One more note:

Mimiri's open-source model also means project development depends partly on community involvement — new features arrive more slowly than in large, commercial note apps with a full-time team, but the direction of development is more resistant to one company suddenly changing product strategy or pricing overnight.

One more thing:

It's also worth checking the project's documentation before self-hosting an instance — the setup process is documented step by step, but requires basic familiarity with Docker or a similar runtime environment.

Comparison with SumizAI:

Mimiri and SumizAI approach note privacy from different angles. Mimiri makes end-to-end encryption the product's foundation, at the cost of some convenience if the key is lost. SumizAI leans on these notes saved as plain Markdown files in a vault the user owns, which gives a different kind of control — full portability and readability of files without a closed format standing in between. Anyone who needs maximum encryption for sensitive professional data will find Mimiri built exactly for that; anyone who wants these notes from AI conversations to land in open text files that can be moved, searched, and archived with any tool will find SumizAI a more flexible approach to their own these notes.

## 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 Mimiri 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.
- Mimiri Notes is open source (GPL-2.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Mimiri 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.
- Mimiri 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 Mimiri 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.
- Mimiri Notes is described as something more than one person uses at once. SumizAI is not: there are no shared vaults, no comments, no permissions and no sync between devices. If the work is a team's, that is a reason to pick Mimiri Notes over SumizAI.
- Mimiri 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.
- Mimiri 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.
