--- title: Wikilinks & Tags description: Connect your notes with links and organize them with tags --- Wikilinks and tags are how you connect your notes. Wikilinks create direct links between notes. Tags let you categorize and filter across your entire workspace. ## Wikilinks A wikilink is a reference to another note, written in double brackets: ``` [[Note Name]] ``` Tap a wikilink in the editor to jump to that note. If the linked note doesn't exist yet, tapping it creates it. ### Linking to Notes in Subfolders If a note lives inside a folder, include the path relative to the workspace root: ``` [[Projects/Design Doc]] [[Work/Meetings/Standup Notes]] ``` The `.md` extension is optional — Octarine adds it automatically. ### The Suggestion Popover Tap the **[[** button in the toolbar (or type `[[` manually) to trigger the suggestion popover. As you type inside the brackets, the popover filters your notes in real time using fuzzy matching. Tap a suggestion to complete the link. ## Tags A tag is any word prefixed with `#` in the body of a note: ``` Working on the new dashboard. #project #frontend ``` Tags are extracted and indexed automatically. They support letters, numbers, underscores, hyphens, and Unicode characters. ### Nested Tags Use `/` to create a tag hierarchy: ``` #work/engineering/backend #priority/high ``` Nested tags let you organize categories at multiple levels. A note tagged `#work/engineering` will also appear under the parent `#work` when browsing. ### Tag Suggestions When you type `#` in the editor, a suggestion popover appears with existing tags from your workspace. This makes it easy to reuse tags consistently without remembering the exact spelling. ## Browsing Tags Open the **Tags** page from the More menu. It displays all tags in your workspace as an indented hierarchy with a note count for each one. - **Search** — filter tags by typing in the search field at the top. - **View notes** — tap a tag to see notes using that tag or any child in its namespace. - **Switch tags** — tap the selected tag in the results header to jump to a different tag without returning to the full index. - **Search results** — use the header search button to filter notes inside the selected tag. If no tags exist yet, the page shows a "No tags found" message. ## Backlinks When note A links to note B via a wikilink, note B records that as a backlink. Open the note, tap the info button in the editor header, and choose **Backlinks**. Backlinks let you discover connections you might not remember — which notes reference the one you're reading.
