Your shared memory

Everything you know,
searchable by meaning.

Notes, documents, quotes, embeds, files, saved AI chats — every neuron is auto-described, auto-tagged, and embedded in your language. One memory. Every AI you use plugs in.

Hybrid retrieval — dense + sparse + reranked87 neurons indexed

Color-coded neurons — notes purple, documents blue, quotes yellow, embeds teal.

Why it matters

Semantic, not keyword

"That thing about the Berlin trip" finds the note titled "European roadmap — Q3" because they're about the same topic.

Cross-language search

Save in Dutch. Ask in English. Cortex embeds in the source language and matches across — no translation step, no missed hits.

Revisions + working notes

Every neuron tracks its history with diff view and one-click restore. A private working_notes scratchpad keeps drafts separate from what you share.

Active scope, every AI

Set the active project; Claude, ChatGPT, Cursor all default to that scope within a second. Switch scope from any client and everyone follows.

How it works

01

Capture

Type, paste, drop a file, forward an email, save a chat from Claude Desktop — every path creates a neuron.

02

Index

Cortex generates embeddings, descriptions, and tags in seconds. Hybrid retrieval: dense + sparse + reranked.

03

Retrieve

Search from the brain view, ask in chat, or call from Claude Code, Cursor, and Claude Desktop via MCP.
