If you've never heard of TheBrain, you're missing one of the most quietly revolutionary tools in knowledge management. While the industry chases the latest PKM flavor of the month, TheBrain has been doing associative, graph-based thinking since the late 1990s. It's not a note-taking app. It's not a wiki. It's a visual graph database for your mind — where every thought connects to every other thought through typed, directional relationships.

I am so happy that you have brought out Cerebro. I was on the verge of moving to Mem because of precisely this ability to talk to my notes. I thought TheBrain had lost the plot on this. Boy, was I wrong! The synthesized overview given by Cerebro is just brilliant - and that's an understatement. I don't use Cerebro much to generate content, but for searching through my notes, it is my absolute go-to. Here's a simple chat prompt I use with Cerebro - "Give me a synthesized overview of ". The output everytime brings a smile to my face. Fantastic. I am firmly back in "TheBrain" saddle. You guys have done a wonderful job with Brain 15.

TheBrain is my favorite digital tool of all time.

I have used TheBrain for many years and I find it invaluable. I am so happy with the way it has improved over the years, and I look forward to seeing how it evolves in the future.

The brain is the greatest tool

Great session and I think The Brain + AI is the best kept secret. Hope more people discover it.

@sirius_callus I have switched to @TheBrainTech and am blown away. True directional graphs linking everything in multiple powerful ways. I think I am in love - highly recommended.

Works exactly like your own brain The Brain is simply the best program/app I have ever found for organizing and connecting complex data. Allows you to make matrixed links across any topic or topics. Works like the old pin and thread bulletin boards detectives use in the movies to find connections between suspects. I have used it for years and am very thankful someone created this program. They keep updating it and improving it. I probably use 20% of the functionality available to me. Also terrific for linking to websites and keeping large amounts of information handy. I would image this would be perfect for someone writing a thesis or organizing a novel. A big Thank you to the team who created it!

25 years and still better. I've used TheBrain on my PC for 25 years, and the mobile app many years too. It's my main web clipper and PKM; there's nothing better!

I use TheBrain app on a daily basis. In fact, it’s the only app on my iPhone that stands alone - not grouped in a folder. Quick notes on any topic. Sending web pages and images through BrainBox. Staying in sync with my laptop. Amazing! I couldn’t function without it!!

TheBrain really is the best model of MindMapiing tools I ever used. I have been faithful to TheBrain for a long time — the most logical, convenient, and fast content organization structure. I wish the development team success, breakthrough ideas, and many customers.

Oh this is soo good!!! Thank you thank you thank you.

I got TheBrain back in 2008 with PersonalBrain 4 Pro, to help me organize many education materials. I fall in love with the idea since then. It is probably one of the few subscriptions I do not feel pain to pay! The continuous improvement is amazing.

I am a very recent intro to the brain. I was earlier using Roam, then I tried Tana... none of them worked for me the way TheBrain is doing. Great work!

This is my favorite program I've ever used. Currently sitting at 56,000 thoughts in my brain with 24 gb of data organized throughout. I've got hobbies involving journalism, history and sociology. This really does a great job of relating things in a similar way that my my mind does. Appreciate all you guys have done to continue support for the Brain. Excited to see what new stuff y'all come up with.

TheBrain is an absolute must! MACos, Windows, iOS and Android versions. Websites, pdfs, important files in laptop folders, notes, brainstorming... thebrain.com @TheBrainTech

TheBrain @TheBrainTech is developing & evolving into the peoples Graphical Knowledge base. With the addition of AI & a powerful already established relational database approach, I envision TheBrain becoming realized as the peoples Database that shall become a global standard.

@TheBrainTech Connect ideas with ultimate software.

I have been using TheBrain now for a few months and I can no longer imagine working without it.

Excellent value. I just love my Brain and could not get by without it.
