RemNote combines a note-taking app with a flashcard system. While you write notes you can mark lines as flashcards, and RemNote schedules them for review with spaced repetition, so you are not keeping separate notes and Anki decks. It also supports handwritten notes, PDF and website annotation, image occlusion cards for diagrams, LaTeX maths cards, tables and templates.
The AI features create flashcards, quizzes and summaries from text, PDFs and slides, grade your answers, chat about your material, convert images to text and transcribe lecture audio. An exam scheduler plans reviews around your exam dates. There are desktop, iPhone and Android apps, and an offline mode.
The free plan has unlimited notes and flashcards on unlimited devices, but only 3 annotated PDFs, 5 image occlusion cards, 1 handwritten document and 250 AI credits a month. The pricing page lists Pro at $8 a month ($96 billed yearly) and Pro with AI at $18 a month ($216 billed yearly) with 20,000 AI credits. A lifetime option is also shown.
RemNote has more features than simpler flashcard apps, so expect a few days to learn it.
