Notes, documents, quotes, embeds, uploaded files, saved AI conversations — all indexed as neurons with AI-generated descriptions. Ask in plain English and Cortex finds it, even if those exact words don't appear anywhere.
Color-coded neurons — notes purple, documents blue, quotes yellow, embeds teal.
Cortex embeds every neuron. "That thing about the Berlin trip" finds the note titled "European roadmap — Q3" because it's about the same topic.
Dense + sparse + reranked. The same query that finds a half-forgotten quote also finds a paragraph in a PDF you uploaded last month.
Every neuron gets AI-generated descriptions and tags the moment it's saved. No manual filing, no forgotten folders.
Set the active project; Claude / ChatGPT / Cursor all default to that scope. Search project-wide or globally with a flag.
Type, paste, drop a file, forward an email, save a chat from Claude Desktop — any path creates a neuron.
Cortex generates embeddings, tags, and a summary in seconds. All searchable.
Search by meaning from the brain view, via AI chat, or through MCP from Claude Code, Cursor, or Claude Desktop.
