Reviews for Capacities
Hear what real users highlight about this tool.
Capacities earns strong praise for its object-based approach that helps users link ideas, surface connections, and keep a living knowledge base. Many report it replaced Notion or Obsidian, citing cleaner UI, faster performance, generous free plan, responsive founders, and helpful daily notes. The learning curve is real, and some want fuller offline mode, task management, imports, and mobile/iPad polish. Notably, makers of Web & Youtube Highlighter + AI Summary say Capacities rethought organization into objects, which aligned with their workflows and even replaced Notion for them.

It broke my brain at first. I’m used to dumping notes into folders or endless pages. Here? Everything’s an object. Projects, books, random ideas — you turn them into little building blocks and connect them. Took me 3 days to stop fighting it.
But when it clicked? Magic. Suddenly my daily notes linked to a personal project, which linked to a book quote I’d saved months ago. Felt like my thoughts were finally talking to each other. The graph view shows these wild connections I never planned.
Daily Notes saved me — perfect for chaotic mornings. Dump thoughts there, then later turn fragments into proper objects.
Downsides: That learning curve is REAL. Not for casual note-takers.
But after 3 weeks I’m hooked. It’s not perfect, but it gets how messy thinking actually works. Lets me wander, then pulls threads together. If you’re tired of notes feeling dead — try it. Just push through day 3.
Capacities is a tool that has replaced Notion for me. Capacities rethinks the way we collect our information. Instead of folder structures, it focuses on organizing things into objects.
Still exploring, but so far so good. It's just what I wanted Notion to be without knowing it. The writing experience may not be quite as elegant or simple as Bear, but it's far more capable.
It's still early days for my knowledge base but this is the best app I've tried so far for the notes I want to keep permanent, as a database/wiki of my brain. One kinda fun, kinda meta use-case I've gotten out of it recently is creating a Software object for every app I use, with views to keep track of trial lengths, billing, thoughts, sort by categories etc. It feels like for this use alone it might win out other apps in the space xD
I love the object based mantra. I am currently in a phase of flipping between this and Obsidian, and I think Capacities is starting to win out (high praise indeed). Really clean UI, and the offline sync is such a blessing - makes my ex-Notion approach feel vindicated.
Great UI, but less overall control than Obsidian. The pro plans are also way too expensive, but the free plan is generous and feature rich.
An object-oriented PKM system that really works for how I think. Already very full featured, mainly just needs polish!
My gosh, this is THE BEST piece of software I used in a WHILE. Ive been on the search for a notetaking app, that would also allow me to save my web bookmarks, and I stumbled upon Capacities. Boy or boy its great! Telegram bot for me is an absolute killer feature. Capacities somehow reminds me of Notion, but it doesn't complicate things when they have to be simple. Also mobile is actually usable unlike notion. I also think developers give away to much for free :) KUDOS to the team! i referred 4 friends of mine right away.
Love it more than Roam or Logseq! The mobile app is quite good as well. Enjoy it so much that I’ve become a paying customer. Keep up the great work, Capacities team and stay true to your vision!
My favorite note-taking app, which doubles as a bookmark manager. Its flexible object-based structure allows you to organize and connect your knowledge the way you want.
Am currently building a strructure to contain all notes on current projects. Great for organising. Takes some getting familiar with but the video tutorials are fantastic.
A little over a year ago I started building my personal PKM, taking the zettelkasten methodology as a reference. After having used several applications that are also quite good; I ended up coming across the recommendation to use the capacities app. Capacities is an intuitive, comfortable, agile and versatile tool that with little effort we can adapt to the particular needs of our workflow. I take advantage of it to keep my diary, my master's notes, my follow-up of pending work; as well as to build my "personal knowledge library" I love the features it currently offers me; and I fully trust that the platform will not stop evolving both in its performance and in the possibilities it offers to users.
A beautifully crafted, object-based note-taking and PKM tool that has become my goto place for taking notes, planning meetings and organising my thoughts for the various writing projects I am working on.
