MCP is an open standard. Cortex exposes your brain as MCP tools. Any client that speaks MCP — current or future — can read and write your memory.

Why it matters

Search across everything

One unified search fans out across your brain, Gmail, and the live web in parallel. Results are merged, deduped, and reranked before the model sees them.

Citations built in

Every claim is linked to the neuron, email, or event it came from. Click through to verify, edit, or expand the source.

Save the whole conversation

A long chat that became a real plan? Save the thread as a summary neuron with cross-references back to the messages.

Use any AI — same memory

Claude.ai via MCP, ChatGPT, Cursor, Claude Code, Slack — they all read from and write to one Cortex.

How it works

01

Ask anything

Talk to Cortex like any chat assistant — natural language, follow-ups welcome.

02

Search, not guess

Cortex queries your brain and connectors before the model speaks. You see thinking steps stream as they happen.

03

Cited + stored

Answers come back with citations. New facts, decisions, or summaries get saved as neurons on request.
