Dende vs Quizzen

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.

Quizzen uses AI to turn documents into quizzes, exams, and assessments. It accepts PDF, Word (.docx), and PowerPoint (.pptx) files, and says scanned PDFs can be processed with OCR. Users choose question counts and difficulty, generating multiple-choice, true/false, or fill-in-the-blank items that can be reviewed and edited before export. PDF and CSV exports are available to all users; paid plans add Moodle XML, Kahoot, and Wooclap formats. Enterprise users can send text to /api/v1/generate and receive structured JSON questions. Uploaded documents are automatically deleted after processing, while the terms say users retain ownership of source documents and generated quizzes. Student features include practice sets, progress tracking, mobile-optimized quizzes, and retakes. The Free plan costs nothing and allows three quizzes every 30 days, up to 10 questions each, with PDFs up to 20 pages. Standard Quiz costs $0.99, paid once; Premium Quiz costs $1.49, paid once. Pro costs $3.99 a month, billed annually at 39.90 USD. Enterprise costs $29 a month, billed annually at 290 USD.
