Tags

Tags are a lightweight way to group related notes (#project, #reading/2026), written inline in your text. This article is about what tags do; the exact syntax for writing one is in HTML and inline extras.

How Myne indexes tags

Myne reads the tags across your notes and treats them as structured metadata:

• Tags fold for matching. #Project and #project are the same tag; accent and case differences are folded together.
• Tags nest with slashes. #area/topic is a tag in its own right, and it also counts under its parent #area, so grouping by #area includes everything beneath it.

Both the inline #tags you write in the body and a frontmatter tags: list feed this same index.

Where tags surface

Tags are interactive in a few places:

• In a note, a #tag renders as a chip. When the cursor is elsewhere, each inline tag shows as a chip; clicking it opens the tag browser filtered to that one tag. To edit a tag, move the cursor into it (the chip turns back into plain text) or delete and retype it.
• The tag browser lets you browse and filter by tag across the whole vault (below).
• The graph view has a tag filter that narrows the graph to notes carrying a tag (and its nested children). See Graph view.

The tag browser

Open the tag browser from the command palette (“Browse tags…”) or the tags button in the bottom bar. It lists every tag in the vault and lets you build a filter:

• Select one or more tags by clicking their chips. A search box narrows the chip list as you type; matching folds case and accents the same way the index does.
• Combine with All or Any. With All, a note must carry every selected tag (AND); with Any, carrying any one of them is enough (OR). Selecting #area includes notes tagged with its nested children, matching the index.
• The matching notes appear in a list below; clicking one opens it.

When you type # in the editor, Myne also suggests existing tags that match what you’ve typed so far. The suggestions are tags that already exist — picking one inserts it. Typing a tag that doesn’t exist yet stays plain text and gets indexed on save like any other inline tag.

Save a tag filter as a view

With one or more tags selected, Save as view turns the current selection (and its All/Any setting) into a saved view, so you can return to the same filtered set later. See Saved views.

Limits

The tag browser and the editor #tag chips browse by tag, but tags are not folders: a note keeps its place in the tree regardless of how it’s tagged. The browser reads the tag index that Myne holds in memory while the vault is unlocked; it is not a separate stored list. Selecting tags in the browser filters notes, but does not change them — the only way to add or remove a tag is to edit the note’s text.
