GalaxyBrain FAQ

How does GalaxyBrain combine document writing and spreadsheet functionality?

GalaxyBrain allows users to input text and information as they would in a document, but also provides underlying capabilities to perform calculations and structure that data in a way similar to a spreadsheet. This enables users to turn free-form notes into organized, computable pages.

What does 'powered by local files' mean for my data?

'Powered by local files' means that all your pages and data within GalaxyBrain are stored directly on your computer's hard drive, rather than on a cloud server. This ensures that you have full ownership and control over your information, and no internet connection is required for access or editing.

Can I use GalaxyBrain on my mobile device or tablet?

Currently, GalaxyBrain is only available on desktop computers. The developers have indicated that it is 'desktop only for now,' suggesting potential future expansion to other platforms, but there is no immediate mobile support.

What kind of AI integrations are supported by GalaxyBrain?

GalaxyBrain is designed to be 'ready for you and any AI you point at it.' While specific AI integrations are not detailed, this implies that the structured nature of the data within GalaxyBrain makes it easily consumable and processable by various AI tools and models that users might choose to employ for analysis, generation, or other tasks.
