Use wordbooks to group your vocabulary

Wordbooks are how you group entries by real-life context — a trip, a book, a class, a project. An entry can live in more than one wordbook at the same time, so the grouping doesn’t force you to pick.

The Wordbooks screen describes them as: “Wordbooks group captured text by real-life context: Trips, books, or moments. An entry can belong to more than one Wordbook.”

Open the Wordbooks screen

There are two ways:

From the Vocabulary tab: open the Filter by wordbook menu and pick Manage wordbooks…
From the bottom navigation: tap the Wordbooks tab if your device shows one.

Create a wordbook

Tap the + floating action button (tooltip “New wordbook”) at the bottom-right. A dialog opens titled “New wordbook” with the field placeholder “Wordbook name”. Type a name and confirm.

Each wordbook is shown as a card with the wordbook icon and a count of entries inside it.

Open a wordbook to manage it

Tap a wordbook’s chip to open the wordbook detail screen. From there you can:

Rename wordbook — opens a dialog titled “Rename wordbook”.
Delete wordbook — confirms before deleting. The entries themselves are not deleted; they just leave this wordbook.
Add definition tag — chip-style button that adds a definition tag (see below).

Definition tags — auto-tagging entries in a wordbook

A definition tag is a tag that’s automatically applied to every entry that’s in this wordbook. If you add the definition tag “japan-trip” to a wordbook, every entry in that wordbook is also tagged “japan-trip” — and stays tagged as long as it’s in the wordbook.

Use them when you want a wordbook’s contents to also be findable as a tag. To add one, tap Add definition tag on the wordbook detail screen, type the tag name, and confirm. The same tag name can’t be both a wordbook name and a definition tag — if you try, you’ll see a message “Wordbook name tag cannot be a definition tag.”

To remove a definition tag, tap the × on its chip in the wordbook detail screen.

Add an entry to a wordbook

Several ways:

One entry, while viewing it: there’s no direct “add to wordbook” button on the detail screen — use the list flow instead.
One entry, from the list: long-press the entry to enter selection mode, then tap Add selected to wordbook.
Many entries at once: select multiple in the list, then Add selected to wordbook.
Automatically while capturing: set a target wordbook before you start capturing.

To remove an entry from a wordbook, use the same selection-mode flow with Remove from wordbook.

Filter your vocab to one wordbook

In the Vocabulary tab, open Filter by wordbook and pick a wordbook. The list now shows only that wordbook’s entries — and the Start Flashcards icon will review only that wordbook. See Finding words in your vocabulary.
