Remember where an idea lives, not just what you named it.
Your hippocampus evolved to navigate rooms and landscapes—not nested folder trees. Arrange PDFs, voice memos, sketches, and Markdown notes on an infinite table, then compile them into linear prose in one click.
A City is Not a Tree (1965)
“Natural cities have the organization of a semi-lattice; artificial cities have the organization of a tree. The tree axiom severs overlapping neighborhoods.”
Kyoto Walk — Spatial Memory
“I always remember which corner of a notebook page an idea was on, never the folder name. Spatial coordinates anchor episodic recall.”
Method of Loci (Mind Palace)
Ancient rhetoricians stored speeches inside imagined architectural rooms. A 2D spatial canvas restores the hippocampus’s native place-cell navigation.
Thesis: Semi-Lattice Interfaces
Combining Alexander’s semi-lattice urbanism with hippocampal place cells: digital second brains must allow spatial neighborhoods that overlap freely.

Drag Highlights Straight onto the Canvas
Open a 90-page research paper alongside your spatial board. Drag any paragraph or diagram out of the PDF to create a live linked card that snaps back to the exact page.
Apple Pencil & Whisper Audio Nodes
Sketch a quick system diagram or drop a voice memo right next to your Markdown notes. Noema indexes handwritten OCR and audio transcripts automatically.
One-Click Manuscript Compiler
Draw a cable thread through 10 cards on your canvas and hit Compile. Noema turns your spatial sequence into a clean hierarchical Markdown draft.
Give your ideas room to breathe.
60fps Metal/WebGL spatial canvas, bidirectional Markdown sync, and offline AI clustering.
