Dwg. IDX—001 · A floor plan for your memory

Build a mind palace you can actually walk through.

Index organizes your notes the way the ancient memory technique does — into rooms you can walk back into, not tags you have to remember.

Note 01 — method

The method of loci, rebuilt in software.

Two thousand years ago, orators memorized long speeches by placing each idea in a room of an imagined building, then recalling the speech by walking through it in order. Index gives every note a room instead of a tag — so finding a thought is less like searching, and more like remembering where you put it.
