Nebulearn is the most time-saving spaced repetition platform. It is seamlessly collaborative, AI native, and gamified. By using Nebulearn, you will spend less time making cards and reviewing what you already know, and more time on the stuff you need to review. Here's how. Frictionless card creation Paste notes, upload a PDF, snap a photo, or record audio and turn it into a deck. Write cards yourself when you want control, with AI autofill for explanations. Generate flashcards or multiple-choice quizzes from your own material instead of typing every card by hand. You stay in charge of the AI. Set difficulty, question count, and custom instructions so cards come out the way you actually study - cloze, definitions, exam-style questions, whatever you need. Smart studying, not extra studying Every card gets scheduled with real spaced repetition, including multiple choice. FSRS is the default: it brings a card back right before you'd forget it, so you don't waste reviews on what you already know. Switch to SM-2 or Leitner, or tune the algorithm. Everything in one place Folders, tags, search, sharing, stats, streaks, and Ask AI live while studying in the same app. There's no need to jump between a generator, a deck manager, and a review tool. Study on your phone, then pick up the same library on the web, with no manual syncing needed. What you get - AI flashcards and quizzes from notes, PDFs, images, and audio - Custom AI profiles and generation instructions - FSRS, SM-2, and Leitner spaced repetition - Image occlusion and photos on cards - Unparalleled question stats and metrics - Mastery stats, consistency, and learning pace - Seamless sharing and collaboration and public decks - Streaks, ELO, and achievements Nebulearn is free to start.
