Man kann während Lückentexten auch KI Aufgaben und Karteikarten wählen. Ich liebe diese App. Vor allem wenn man vorher nicht wusste wie man richtig für Arbeiten und Klausuren lernt. Das hier ist die perfekte App. Ich lerne damit viel besser. ### 4/5 — KI-Karteikarten *2025-03-28, version 1.6.13* Ich finde die App super! Es hilft total beim lernen und man hat immer die Möglichkeit auf die einzelnen Stapel zurück zu greifen. Ich empfehle die App gerne weiter! ### 5/5 — So eine tolle App! *2025-02-16, version 1.6.10* Ich bin so überrascht, dass einfach alles kostenlos ist. So toll! ### 5/5 — .. *2025-02-01, version 1.6.9* Gute App nur schade das sie immer sehr gut Internet Verbindung braucht ### 1/5 — Need to register before use *2024-11-30, version 1.6.4* I don’t know what the app is like but it’s off-putting if the first thing I need to do is to register and give my email address and name in order to use the app. This app is a learning app so there is absolutely no reason for a registration in any form. Uninstalled instantly ### 5/5 — Great App !! *2024-07-25, version 1.6.1* This is the future of flashcards. Using AI we are able to generate cards seamlessly and I can generated very easily saving me a lot of time. It also allows me to focus more on the learning of the flashcards rather than the building of the deck which AI does for me saving me time. ### 5/5 — Excellent AI card generation features *2024-05-22, version 1.6* As a experienced Anki user I find this app to be a great tool to generate cards quickly for new subject areas that you want to explore or go deeper into. It is beautifully designed and makes some great cards for the prompts you provide. This app is perfect if you want to test your knowledge for an exam without reusing the same revision materials over and over again. ### 5/5 — Great app with awesome features *2024-05-05, version 1.4* Finding this flashcard app really useful. The AI is well integrated, and it’s a pleasure to use. Top marks 👍🏻 ### 5/5 — Wonderful! *2024-04-09, version 1.0* Love everything about it ## Frequently asked questions about Retain ### How does Retain use AI for flashcards?
