Every note you link, on one map you can explore

Link one note to another with [[ and LunaNotes draws the line. The graph puts a whole workspace on one canvas, sized by how connected each note is and coloured by its tag. Try it: point at a note.

A knowledge graph of 15 linked biology notes. The Calvin cycle is focused: two links out, four links in.

Every line starts as a [[ in a note

You don't draw the graph. You write, and link a note to the ones it builds on. Each link becomes a line from this note to that one.

Type [[ to link
Pick a note from the list, or create a new one from the same menu. The / menu's Link to Note does the same.
Counted, not doubled
Link to the same note again and it stays one line, counted twice and drawn a little heavier.
Rename freely
A link points at the note itself, not its title. Rename a note and every line to it stays.
Drawn after you save
Links are added to the graph in the background, moments after the note saves.

Read a course at a glance

Four things carry the meaning. Once you know them, a minute with the graph tells you what a course hangs on and where the gaps are.

  • Size is how linked it is

    Links in and out both count. The notes your course hangs on are the big ones.

  • Colour is its first tag

    The first tag you gave a note colours it, so a course's topics read as regions. Untagged notes stay grey.

  • Hover shows the direction

    Point at a note: lines it sends turn amber, lines it receives turn bold, and the rest fades back.

  • Distance is how close the ideas are

    Linked notes pull together and unrelated ones drift apart. A note between two clusters is the one that ties them.

Find the notes nothing links to

A note with no links in or out is an orphan. The graph hides them so the shape stays readable, then brings them back with one switch.

  1. 1

    Find them

    Turn on Show orphans. The switch says how many there are.

  2. 2

    Open one

    Click any note on the graph and it opens.

  3. 3

    Give it a place

    Type [[ in it, or link to it from a note that should mention it. Next time, it is part of the map.

No links at all yet? Then every note shows from the start, so a new graph is never blank.

Each workspace has its own graph, and each member sees their part

Share a course's workspace and everyone in it can open its graph. What each person sees is drawn from the notes they can open.

One graph per workspace
Each workspace draws its own notes. Switch workspace in the sidebar and the graph follows.
Only what you can open
A note that isn't shared with you is not on your graph, and neither are its lines.
Links stay inside
A link only connects notes in the same workspace, so one course's map never pulls in another's.
