Your second brain,finally in focus.

Capture ideas the moment they arrive. Cortex links them so recall feels automatic.

Capture at the speed of thought

Global hotkey, mobile share, or quick-add window. The note is saved before you finish the sentence.

Every connection is visible from both ends. Old notes wake up when new ones touch them.

Ask naturally. Cortex ranks passages by intent, not by exact keyword matches.

Encrypted on device. Cloud sync is optional and can be turned off without losing history.

All capture paths land in a single stream you can sort later.

Suggested links stay suggestions until you accept them.

Plain folders, open formats, no proprietary lock-in.

Free for personal libraries. Works offline. Export whenever you want.
