Tags

Tags are simple labels you attach to notes to group related material. The Tags panel gathers every tag in your project into one alphabetical list, and clicking a tag shows you everything that carries it. It's a way to browse and filter — you add and remove tags in a note itself, not here.

Where tags come from

There are two ways to tag a note, and both feed the same list.

In a note's properties
List tags in the properties at the top of a note, for example tags: [neuroscience, consciousness]. See Properties for details.
Inline while writing
Type a # directly followed by a word anywhere in a note — #draft, #project/ui. The tag runs until the next space or punctuation.
Headings aren't tags

A heading like # Heading has a space after the #, so it's never mistaken for a tag. To tag something, write #tag with no space. A # inside a code sample is ignored too, so it won't clutter your tag list.

What the panel shows

Tags appear as chips sorted alphabetically, each labelled with the tag name and a count.

Count
The number tells you how many notes carry the tag — and how many sources too, when the sources toggle is on. Hover a chip for the exact breakdown, such as "3 notes, 1 source."
Chip size
Your most-used tags appear slightly larger, a quick visual cue for which topics dominate your project.
Highlighted tags
A couple of special tags — entrypoint and open-question — always stand out in the accent color, because they mark places worth returning to.
Sources toggle
A checkbox above the list, on by default, includes tagged sources alongside tagged notes. Turn it off to see notes only.
A wrapped row of tag chips sorted alphabetically, with one chip highlighted as selected. Beneath it, a "Tagged #neuroscience" section lists the matching notes and sources.

Selecting a tag

Click a chip to see everything that carries that tag. Matching notes and sources are listed right below the chips. Click a note to open it in the editor, or a source to open it in the source viewer.

One tag is active at a time — clicking another chip switches to it. Click the active chip again to deselect it and clear the results.

This is a separate list

Selecting a tag doesn't change what's shown in the Notes tree. It builds its own list of matches inside the Tags panel; your full notes list stays exactly as you left it.
