Organize cards with tags

Tags let you group cards across decks without moving them. For example, use travel, verbs, or needs-example to mark material you want to find later.

A card can have up to five tags.

Add tags to a card

  1. Open an existing card, or start Add Card → Enter manually.
  2. Tap the info button to open Card Info.
  3. In Tag Info, open Select Tag.
  4. Search for and select the tags you want. Use New Tag when you need a new label.
  5. Confirm the selection, return to the card editor, and tap Save or Add Card.

The selected tags belong to that card. Tag changes made while preparing imported or AI-generated cards remain part of those drafts until you add the cards to the deck.

Manage your tag list

Open Settings → Tags to find and manage saved tags. Open a tag to change its label or delete it.

Deleting a tag removes the tag association from cards; it does not delete the cards themselves. Renaming an existing tag changes the shared label, so you do not have to update every tagged card individually.

Show or hide tags during practice

In Deck Setting → Study Setting → Flashcard, use Show Tag. During a Flashcard session, the card action menu also provides Hide Tag or Show Tag.

Hiding tags changes what you see during review. It does not remove the tags or stop them being usable in Search.

Use tags consistently

Choose a small set of labels with distinct meanings. A topic such as travel works well as a tag; the question and answer themselves belong in fields. Use the main Search tab's tag filters when you want to find cards with a particular label.
