Tags

The three-tier hierarchy answers "where does this note live". Tags answer "what kind of thing is it". A note sits in exactly one place, but it can carry any number of tags — method, to-read, customer-interview each cut across the whole library.

Adding Tags

The tag field sits under the note title. Click it to edit:

• Separate tags with spaces: method survey to-read adds three at once
• To keep a space inside a tag name, quote it: "design thinking"
• No # needed — the chip supplies it, and a typed # is stripped automatically
• Tags are stored lowercase: Method and method are the same tag, not two

Tagging as you write in Quick Note is the cheapest way to make a note findable later — see Quick Capture.

Tag Suggestions

A row of outlined chips appears beneath the tag field: tags carried by the notes closest to this one in meaning. Click one to adopt it.

• Candidates come only from tags already in your library — it never invents a word, so your tag set does not sprawl
• At most three; when there is nothing to suggest, the row does not appear at all
• It is worked out entirely on your device, with no model call: no network, no cost, works offline
• Which is why it is available on the free tier and needs no API key

TIP

An outlined chip is still only a suggestion; a filled chip is already one of the note's tags. The one you click disappears from the suggestion row immediately.

Filtering by Tag

Every list — in all three views — has a Tags section in its filter menu. Tick a tag to narrow the list to notes carrying it. Selecting several tags is a union: a note matching any of them stays.

The funnel icon turns accent-coloured whenever the list is filtered or re-sorted. Clearing it clears the filters only; sorting goes back to default through By / Order.

The free tier filters by one condition at a time

On the free tier, at most one of Tags, Nodes and Theme can be active, and Tags and Nodes allow one selection each — crossing them is a Pro capability. Locked options remain visible (greyed out with a lock) and tell you why when clicked. Sorting, search and the trash are not affected. See Free vs Pro.

Tags Applied for You

Two kinds of note arrive pre-tagged, so the whole batch is one filter away later:

Tag	Comes from
clipping	PopClip and Raycast captures
browser-capture	Save to Note in the AI chat panel

Both are covered in Quick Capture.

Tags vs Nodes

Both look like "a word attached to a note", but they are different things:

	Tag	Node
What it is	A classification marker	A concept that has content of its own
How you make one	Type it in the tag field	Write [[concept name]] in the body
Can you open it	No — it is a filter, nothing more	Yes: a node has its own page, backlinks and relations
In the graph	No	Yes — the graph and the co-occurrence matrix are built on nodes
Good for	Status, source, kind (to-read, interview, method)	The things you are actually thinking about (first principles, user retention)

Rule of thumb: if you will ever want to open it and see what else relates to it, it should be a node, not a tag.
