# Tags Explorer & Sidebar

> Organize StrataNote notes with #tag syntax and inline chips, browse the dedicated Tags sidebar, and map tag relationships on the interactive graph.

StrataNote treats tags as a first-class way to organize notes across folders. You can write tags inside your notes, browse them from a dedicated sidebar tab, preview them on document cards, and see tag-based relationships on the interactive graph.

## Adding Tags to a Note

Add tags anywhere inside a note using the standard `#tag` syntax:

```markdown theme={null}
# Weekly Review

Notes from this week's planning session.

#project/alpha #status/in-progress #team
```

Tags support nested hierarchies with the `/` separator (for example, `#project/alpha`), so you can group related tags without flattening them into a single namespace.

## Tags Sidebar Tab

Open the **Tags** tab in the left sidebar to browse every tag detected across your vault.

* **Tag list:** All tags are listed alphabetically with a badge showing how many notes reference each tag.
* **Nested groups:** Tags with `/` in their name are grouped into a collapsible tree so you can drill down from a parent tag (e.g. `project`) into its children (`project/alpha`, `project/beta`).
* **Click to filter:** Selecting a tag filters the current view to notes that reference it.

## Inline Tag Chips

When you open a note in preview mode, tags parsed from the note body are rendered as inline chips at the top of the document. Chips are clickable — selecting one jumps you back to the Tags sidebar with that tag pre-selected, making it easy to pivot between related notes.

***

## Searching by Tag

The search panel supports a strict tag filter in addition to full-text and semantic modes. Prefix your query with `#` to match only tags:

```text theme={null}
#project/alpha
```

Results are limited to notes that actually contain the tag, without matching similar words in the note body. See [Searching the Knowledge Base](/user-guides/search) for the other search modes.

## Tags on the Graph

The interactive graph maps tag relationships alongside Wikilinks and semantic similarity. Notes that share a tag are connected by a lightweight tag edge, so clusters of tagged content emerge naturally next to the existing link and similarity clusters. See [Interactive Connections Graph](/user-guides/graph) for filtering and layout controls.
