What our users say

Sure thing - you are building the notes app of my dreams β™₯️
I'm using Obsidian, but I'm willing to switch to Capacities for so many reasons
I wanted to congratulate & thank you guys for creating such an intuitive and beautiful piece of software ❀️
I have tried a ton of Note apps over the past month. Wow, I am very impressed of what you have here. Keep up the great work.
I am extremely excited about capacities.io, and I know it will become an invaluable tool for many people. Already, it has become a daily tool for me.

Please do not stop and keep going.
Just signed up for capacities and I must say I am amazed. I have tried all PKM systems and this one ups notion big time. Very well done.
As a product person who used Workflowy, Roam and Obsidian, I am very impressed by your unique product insight (Types).
I am testing capacities since yesterday and I'm super excited. So far I've been using Obsidian.
User interface and usability is great in this app! Congrats!
I just wanted to touch base to say I am checking out your capacities app. I have only used it a couple of days, but am enjoying it very much. It is beautifully designed. Keep up the great work!!!
Hello, I just thought I would write to say that since I had the onboarding call with Steffen in mid-May, it's been really helpful for me to use capacities even more powerfully. Since the newest update, it has been AMAZING to use. You are going in all of the right directions. Thank you.
Thank you for creating this wonderful app.
To be honest, I’ve tried Notion, Roam, Reflect, Obsidian, etc. pretty much every PKM system out there and I really hope you guys succeed in building your vision as I really enjoy using it.
Just wanted to say, this app is fucking awesome! Exactly the kind of thing I've been looking for. Kinda what I thought Anytype.io was going to be able to do, but WAY better and more powerful.
