Dende vs PrepAI

Dende is a web study tool that turns learning materials into quizzes, flashcards and a study plan for exam preparation. It accepts PDF, Word, PPT and TXT files, including scans, and supports any language. Quizzes draw from document content and can use multiple choice, fill-in-the-blank or true-or-false questions. Dende gives feedback after each answer and tracks progress to help learners identify topics needing attention. It also makes flashcards for active recall. Learners can rate their confidence in a card, and cards they are still learning are shown sooner. Generated questions and answers are editable; cards can include images or highlighted text and be grouped into custom decks. Flashcards can be reviewed from any device, including mobile. Dende says results from handwritten notes depend on their quality and recommends digital files, including scans. The free plan allows one file upload and limited questions. Premium costs €6.90 per month and includes unlimited uploads and all questions.
