Notecosm
See what your notes know
Only for Mac

Point Notecosm at your notes folder and watch it draw the map: notes that mean similar things sit together, whether or not you ever linked them.
Notecosm turns a folder of notes into a map you can walk through.
Every note is a star. Notes that mean similar things sit near each other and are joined — not because you linked them, but because Notecosm read them. Groups appear on their own, each with a name, and what you have been thinking about for years is suddenly a shape you can see.
It reads the notes you already have, where they already are: any folder of Markdown or text, an Obsidian vault included. Write a new note or fix a line without leaving the map — Notecosm writes only what you write, only in the folder you chose, and never touches a file that changed somewhere else while you were reading it.
SEE THE SHAPE OF WHAT YOU KNOW
A map of every note, grouped by meaning, in two dimensions or three. Click a star to read the note and see what it sits near.
SEARCH BY MEANING, AND BY THE WORDS
Ask for "brewing coffee" and find the note that says espresso. Paste an exact file name or identifier and find that, too — both searches run together, and the map lights up where the answers are.
ASK A QUESTION
With Apple Intelligence on, Notecosm answers from the notes that matter and shows you which ones it used.
WRITE WHERE YOU READ
A new note goes into the group you are looking at. Edit any note in place, with the markdown on buttons.
NOTHING LEAVES THIS MAC
No account, no server, no upload. Reading, grouping, searching and answering all happen on your Mac.
