Obsidian and Capacities
Where object-based PKM differs

If you want to manage the location and format of the file yourself, Obsidian is a candidate, and Capacities is a candidate if you want to have the same attributes for each book or person. Obsidian also has properties, so you can't choose only "whether there are attributes". The axis of decision is whether to use the attribute design with your own group of notes or summarize it into an object type of the app. This is an organization based on Obsidian's property specification and Capacities's object type specification.

The following actual screen is the first demo before login of Capacities. I checked the input into the daily memo and the display of the sample book. It is not a review that has completed regular use, synchronization, or migration after account creation.

Obsidian properties are retained as YAML at the beginning of the note. You can also include attributes in the template. For example, you can design your own reading notes such as the following. This is an explanatory description example, and it is not the result of running it in the app this time. Refer to official property specification.

In Capacities, properties define the fields an object type can contain. The official documentation also describes Object Select, which selects notes of a specified type. You can choose whether to record a person as text or link to a note about that person, which may suit following an author’s other work from reading notes. This explanation is based on the Capacities property specification; we did not test creating custom types.

In the official description of Capacities, after downloading the note to the terminal, it can be edited offline and synchronized when returning to online. However, full-text search and AI cannot be used, and images, etc. depend on the acquisition status of the terminal. The normal storage destination is its own database, and it is not in the form of directly opening the same folder as the Obsidian repository and co-editing. Based on Offline Support.

If you often use it on the go, it will be easier to determine whether "the necessary notes have been acquired to the terminal" and "search and attachments are also necessary" at the time of introduction. This time, we have not conducted an experiment to block the line, reconnect, or resolve the competition.

The official export guide says that attributes are exported as front matter, collections as CSV and links between notes as local links. Automatic export requires a destination and an active schedule, and the app must be open at the scheduled time. This was checked against Exports and Backups.

In the actual migration, it is a good idea to prepare a small number of books, people, and daily notes, and check whether the text, links, attributes, and images can be read in the exported file before adding more targets. This article does not export or import to Obsidian. It is not possible to determine that all displays and operations will be the same with the migration destination based on the specification that can be exported.

In the official price list of Capacities confirmed on September 6, 2026, Basic is free and includes custom object type, inter-terminal synchronization, import and export. The media is up to 5GB in total, and the subsequent upload is a separate frame of 100MB per month. The latest conditions, including paid functions and billing cycles, can be found in official price list.

The first thing to choose is management rather than plan. When you continue to make the same reading notes, compare whether it is easier to write if you have the attributes, or whether it is easier to look back if you develop your own file structure. The price-only comparison is Obsidian's price guide, and the file-centered alternative candidate is Obsidian and Logseq comparison.

This is not an article in partnership with the comparison target. This site is operated by YURIKA, K.K., and information about the independent app "SimpleMemo" is also posted.
