--- description: "Tags are Jotaid's crosswise classification: how to add them, where the semantic tag suggestions come from, and how a tag differs from a node." --- # 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](https://docs.jotaid.com/en/guide/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](https://docs.jotaid.com/en/guide/pricing). ## 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](https://docs.jotaid.com/en/guide/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. ## Next Steps - [Creating Nodes](https://docs.jotaid.com/en/guide/create-nodes) — Nodes and the network they form - [Projects](https://docs.jotaid.com/en/guide/projects) — The vertical Project / Theme / Note structure - [Quick Capture](https://docs.jotaid.com/en/guide/capture) — Tagging as you capture
