We re-invented personal knowledge management from the ground up.

Instant recall

Our brains work by looking up relevant thoughts when we need to think and work on something specific. However, our memory is very limited, and we often make big mistakes due to this. Constella brings up related notes when you need them.

Networked connections

We learn when our neurons form connections between each other. Similarly, Constella lets you draw connections between notes visually to build knowledge from your notes rather than just loose facts.
