description: "Mimir vs. Capacities: plain pages and bullets, or typed objects with fields. Where notes live, price, and which to choose."
---

Capacities organizes notes as *objects* of different types: a person, a
book, a meeting, or a type you define. Each type has its own fields and
layout, and a daily note ties each day's writing together. Mimir has one
kind of thing, the bullet, on pages joined by `[[wikilinks]]`.

Checked on 2026-10-11.

## Which to choose

Choose Mimir if you want to write without deciding what kind of thing
each note is. Your notes stay on your device and work offline, and on
iPhone and iPad you write, link, and search the same as on a Mac. Cloud
Sync is a one-time purchase.

Choose Capacities if you want typed objects with their own fields, an AI
assistant, free sync on every plan, or an app in the browser and on
Windows, Linux, and Android. Its mobile app works as a companion to the
desktop app.

Capacities suits notes that need structure. Mimir suits writing and
linking.

## Where Capacities is heading

Capacities releases updates every month. Its August and September 2026 releases
added larger AI plans, version history, PDF annotation, and audio
recording with transcription.

## Price

The free plan includes unlimited notes, sync across all devices, offline
use, and 5 GB of uploads. Pro costs $9.99 a month, with 16% off yearly,
and adds an AI assistant, tasks, queries, calendar integration, and
version history. Believer, from $12.49 a month, adds early access to new
features. A larger AI budget is an add-on, from $8.33 a month billed
yearly.

Mimir is free on every device. Syncing between devices is the one paid
feature, a one-time purchase rather than a subscription.

## What they share

- A note for each day, as a place to start writing.
- Links between notes, and a list of what links to each one.
- Search across everything you wrote.

## Where they differ

- In Capacities, you decide what kind of thing each note
  is, and give each type its own fields. Mimir has pages and bullets and
  no types or fields.
- Capacities keeps your notes on its servers
  and caches them for offline use. Mimir keeps your notes in a file on
  your device.
- Capacities Pro includes an AI assistant that can chat about and
  edit your notes. Mimir has no AI built in.
- Capacities runs in any browser and on Windows, Linux,
  and Android. Mimir runs on Mac, iPhone, and iPad today.

## What people say

People praise Capacities for being easier to start with than other
structured tools, and for a generous free plan. The common complaint is
that the mobile app does less than the desktop app.

**On iPhone and iPad**, Capacities has 4.3 out of 5 stars from 114
ratings on the US App Store. Reviewers call it a companion to the desktop
app: you can't create new object types on it, and text selection feels
clumsy.
