Flashka
Flashka turns your notes, PDFs, and slides into flashcards, quizzes, and spaced-repetition study sessions. Upload a document or highlight text, and the app generates study materials you can edit, organize, and review on a schedule tuned to how memory works.
The platform supports four flashcard formats (basic Q&A, cloze deletion, term/definition, and multiple choice), plus image occlusion cards for diagrams. An SM2-based spaced repetition engine schedules reviews so you revisit material right before you'd forget it. Quizzes tie back to your generated cards, and Professor Ka can explain mistakes or clarify card content on demand.
Built by former students who launched in January 2024, Flashka targets anyone cramming for exams across medicine, law, languages, and other subjects. The site reports use by more than 1.2 million students in 100+ countries, with an interface available in many languages.
