Topic library
Ready-made topics, curated for you
The topic library has ready-made flashcard topics you add to your library with one tap and study with the five Leitner boxes. Every topic is curated, with sources and image licenses. The topic library is part of Flashcards Plus.
Available topics
Two topics are available today: one for learning vocabulary and one for computer science basics, useful for exam preparation.

¡Hola! — Hello!
Add it, then make it yours
An added topic becomes an ordinary topic in your library. Edit any card, delete the ones you already know, add your own, and study it with the same Leitner boxes as everything else. If a library topic is updated, adding it again merges the changes instead of creating duplicates.
Curated, with sources
Library topics are written and checked by hand, not generated in bulk. Cards are short, with one fact or one question each, and images come with their source and license, for example public-domain diagrams from Wikimedia Commons and Microsoft’s Fluent Emoji (MIT license).
Questions about the topic library
Is the topic library free?
No. The topic library is part of Flashcards Plus, together with sync, partners and AI. Once added, a topic is yours and stays on your device even if Plus ends.
Can I edit ready-made topics?
Yes. An added topic is an ordinary topic in your library: edit, delete or add cards as you like.
Which languages are available?
Today both topics are available in English, German and Spanish. The app shows the version that matches your app language and falls back to English otherwise.
