Renaming of Related Thoughts

When you rename a thought, related thoughts are automatically renamed if you are using context-sensitive names (AKA the "comma trick").

Integrated Content Previews

Images, PDFs, web pages and more load automatically for instant viewing. Quick Look on macOS and File Preview on Windows are tighty integrated.

Embedded Browser

Web attachments appear right inside TheBrain 9, letting you access web information without even having to open it in a separate browser.

Timeline View

The all-new timeline view smoothly scales to show you your day, week, month, or even year at a glance. Events can be color-coded and associated directly with thoughts and links.

Tag Icons and Abbreviations

Tags can be assigned icons and abbreviations that appear right next to the tagged thoughts for instant recognition. This also lets you use tags to add multiple icons to thoughts.

Mind Map View

Mind map view is perfect when you want to focus on one area of your Brain. Re-orient the mind map at any time.


Changes are automatically logged so you can review the individual history of each item in your Brain.

Offline Mobile Access

The iOS and Android apps for TheBrain 9 are vastly improved, including the ability to sync your Brain so you can access it without an Internet connection.

Much More

Since everything is new, there are improvements throughout, including: better properties access, Brain management, colors, thought ordering, searching in reports…
