Brain & neurons
Everything you save is a neuron — a searchable unit of memory.
What a neuron is
A neuron is one unit of memory: a note, a document, a prompt, a quote, or an embed. The Brain page lists all of them — newest first, filterable by kind, project, date, and search.
- Notes — free-form Markdown. The default for everything you jot down.
- Documents — uploaded files (PDFs, images, audio). Cortex extracts and indexes the content.
- Prompts — reusable prompt templates your AI assistants can fetch by name.
- Quotes — passages worth keeping, with their source.
- Embeds — links that keep their context (the page you saved, not just the URL).
Capturing
Create a neuron with “+ New”, drop a file anywhere in the app, click the microphone to record a voice note (it is transcribed into a note automatically), or save directly from an AI conversation through an MCP connection.
Images run through vision analysis on upload — the extracted description becomes searchable, so “that whiteboard photo from March” actually turns up.
Organizing
Tags, pinning, and archiving keep the list workable. Pinned neurons stay on top; archived ones leave the default view but stay searchable. Every neuron can belong to a project and carry a visibility level (private, team, or public link).
