Wikilinks & 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.

The # Toolbar Button

Tap the # button in the toolbar to start typing a tag. The suggestion popover appears with existing tags from your workspace, so you can reuse tags consistently.

Browsing Tags

Open the Tags page from the More menu. It displays all tags in your workspace as a hierarchical tree.

• Search — filter tags by typing in the search field at the top.
• Expand/collapse — tap a parent tag to show or hide its children.
• View notes — tap any tag to see a list of every note that uses it.

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. You can see a note's backlinks in the Backlinks tab of the Note Info panel (swipe from the right edge of the editor).

Backlinks let you discover connections you might not remember — which notes reference the one you're reading.
