StudyCards AI

RemNote

RemNote combines note-taking, flashcard creation, PDF annotation, and AI-powered study tools into one app built around helping students retain what they learn, not just record it. Notes can be automatically or manually converted into flashcards, which are then reviewed using a spaced repetition algorithm that schedules reviews at optimal intervals for memory retention. Beyond flashcards, RemNote supports PDF and PowerPoint annotation, typed and handwritten notes, an AI tutor chat, and databases for organizing course material, positioning itself as a replacement for juggling separate tools like Quizlet, Anki, Notion, and Evernote.

MarginNote

MarginNote is a study and knowledge-management app for Mac and iPad, positioned as a place 'where deep reading leaves a trace.' It integrates PDF/EPUB annotation, mind mapping, and an FSRS-based spaced-repetition flashcard system so that highlights and notes automatically become study cards across multiple linked formats.

Flashcard Generator

A free AI-powered flashcard generator that converts PDFs, documents, notes, images, videos, audio, and YouTube links into flashcards in seconds. Powered by Google Gemini, it requires no signup and supports editing and sharing decks.

Brainscape

Brainscape is a digital flashcard platform built around Confidence-Based Repetition (CBR), where learners rate how well they know each card and the app adjusts review frequency accordingly to focus time on weaker material. It can automatically generate flashcards from uploaded PDFs, PowerPoints, Word documents, Excel files, and videos using AI.

StudyFetch

StudyFetch is an AI-powered study platform that converts a student's own course materials, including PDFs, lecture slides, recordings, YouTube videos, and even photos of handwritten notes, into flashcards, quizzes, summaries, and a personal AI tutor called Spark.E. Because Spark.E is trained on the uploaded material, it answers questions based on the student's actual textbook and lecture content rather than generic answers.

StudySmarter

StudySmarter is an all-in-one study platform for university and secondary school students, combining flashcard creation, note-taking, and AI-powered explanations in one app. Students can convert lecture slides into flashcards, take AI-generated mock exams with instant feedback, and access millions of community-created study sets alongside their own material.
