Studyflash is an AI study app from Switzerland. You upload your own course material, such as a lecture PDF, PowerPoint slides, Word notes, photos of handwritten notes or a live lecture recording, and it builds study material from it: flashcards, quizzes, summaries and mind maps.
It then plans your revision with spaced repetition, so cards you find hard come back sooner. An AI tutor called Max answers questions about your material and points to the source passage. Premium adds timed and graded mock exams (which can be modelled on old papers), two-voice audio podcasts about your notes, and unlimited study groups. There are web, iPhone and Android apps, and the phone apps can show already-made cards offline.
The free plan needs no card and shows no ads. It covers flashcards, quizzes, summaries, mind maps and spaced repetition, with a monthly allowance for creating new material and unlimited chat with the tutor. The pricing page does not publish Premium prices; it says the app shows the price for your country before you pay, and that App Store or Google Play prices can differ from the web price. There is no Premium trial.
Always check AI-made cards against your textbook, especially for numerical subjects.
