Your mind

Everything you capture lives in one private, searchable view, and a living 3D brain shows what your lens knows.

Your brain, in one place

Knowledge is where everything you have captured lives. Facts, pasted text, links, PDFs, transcripts, images: all in one searchable view. It is the private core of your second brain, and it is what every lens draws from when you share a slice of it.

What you can do here

  • Search across everything you have captured.
  • Filter by type, by space, or by source.
  • Open a source to see how it was split into chunks and what the AI can quote.
  • Edit or remove anything that is wrong or out of date.
  • Move items between spaces to change what your lenses can see.

For browsing and cleanup in depth, see Library and Search and review.

Capture fast, tend later

Capturing is the fast door: drop something in and keep moving (see Adding knowledge). Knowledge is the workshop: browse, organize, fix, and prune. Same knowledge base, two ways in.

A clean mind makes every answer better, in your private chat and in every lens you share. Time spent tidying here pays off everywhere else.

The Graph button

Click Graph in the top-right of Knowledge and your lens’s brain opens full screen. Everything the current lens knows (notes, documents, links, transcripts) floats inside it as a point of light, grouped into clusters by meaning. Related ideas sit close together, and the connections between them glow as the brain slowly turns.

The counter in the corner shows how many neurons (pieces of knowledge) it holds and how many times it grew today. When your lens learns something new, a small red tick appears on the Graph button: the brain grew while you weren’t looking.

Watch it grow

Add something: drop a PDF into the page, speak a voice note, paste a YouTube link. When processing finishes, the brain updates by itself. A pulse rings out, the counter rolls up, and the new knowledge takes its place among the clusters. A brand-new lens starts as a faint breathing core; feed it and it takes shape.

Explore it

  • Drag to rotate, scroll or pinch to fly inside.
  • Hover over a point to wake its neighborhood and see what it is.
  • Tap a point to close the brain and search your library for it.
  • Press Esc (or the ✕ in the corner) to come back.

Visitors see this same brain on your public lens page. It is built only from what the lens is allowed to know.
