RemNote is an all-in-one learning platform that fuses note-taking, PDF annotation, and spaced-repetition flashcards into a single app, so students never have to bounce between Notion, Anki, and Quizlet. Born at MIT in 2020, it lets learners write notes and turn them into flashcards instantly - or let its AI generate cards, quizzes, and summaries from PDFs, lectures, and videos. Backed by a $2.8M seed round and used by hundreds of thousands of learners (especially medical and pre-med students), RemNote aims to reinvent how people learn, think, and remember.
Course Hero is an online learning platform that gives students access to crowd-sourced study materials, AI-powered explanations, expert tutors and practice problems. Founded in 2006 at Cornell, it grew into an edtech unicorn and now anchors Learneo, the parent company that also owns QuillBot, CliffsNotes, Symbolab, LitCharts, Scribbr and LanguageTool.
Quizlet is an American education technology company that built the world's most-used flashcard app and is now retooling itself as an AI-powered study coach. Founded in 2005 by a 15-year-old high schooler studying for a French final, it has grown into a platform used by tens of millions of students each month across more than 130 countries.
