See the above table for key product differences. If you are using PersonalBrain simply to organize personal ideas and Web pages, it's yours for free. This version was designed for users on an extremely low budget.

If you are currently using PersonalBrain 3 we recommend upgrading to at least PersonalBrain Core so you don't miss the use of files. This gives you next generation Brain technology that includes zoomable icons and expanded views, themes and more.

If you want to take your Brain to the limit, go for PersonalBrain Pro. It offers the most powerful toolset for organizing your thinking and information. Multiple attachments, reminders, spellchecking, and filtering will all help you save time and be more productive. Not to mention, exporting your Brain as HTML means you can easily share your Brain with the world!

The cost to upgrading from Core to Pro is simply the difference in price. There is no additional charge.

Upgrades within the current major version of the software (e.g. from 5.0 to 5.5) are always free. Upgrades to any new major release (e.g. from 5.X to 6.X) made within 3 months from your intial date of purchase (not including upgrades) are also free.

Upgrades to a new major release vary in price as outlined below.

PersonalBrain 6 is faster, more reliable, and has over 100 enhancements and fixes including many user interface improvements and the ability to sync your Brain online. View the highlights of PersonalBrain 6 on the what's new page.

If you qualify for a free upgrade to version 6 you can get your free ugprade by filling out the free upgrade form.
