Wikilinks & Tags
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.
