THINK
BIGGER.
Cortex is the modular second brain for ambitious minds. Structured, powerful, and unapologetically bold. Your knowledge system, engineered.
The System
Structured Notes
Templates, schemas, and types. Your notes aren't just text — they're typed data you can query and transform.
Graph Engine
Every note is a node with typed edges. Filter, traverse, and visualize your knowledge like a database.
Block Modules
Composable content blocks — tables, kanban, calendars, code. Build the views you need.
Command Bar
Keyboard-first navigation. Find anything, run any command, never leave the keyboard.
API Access
Full REST & GraphQL APIs. Your brain shouldn't be a walled garden — integrate everything.
Self-hosted
Own your data. Deploy on your own infrastructure with a single Docker command.
Cortex is what Notion would be if it was designed by an engineer who actually uses their own product. Structured, fast, no fluff.
Stop collecting.
Start connecting.
Your knowledge deserves a proper system. Build it with Cortex.
