Turn any PDF into flashcards

Upload a PDF — lecture slides, textbook chapters, study guides, or your own notes. AI reads the document, identifies the key concepts, and generates a flashcard deck you can start reviewing immediately. Powered by FSRS v6 spaced repetition for long-term retention.

How it works

1
Upload your PDF

Drag and drop or select any PDF file — lecture slides, textbook chapters, research papers, or handwritten notes scanned to PDF.

2
AI identifies key concepts

The document is analyzed to extract the most important terms, definitions, processes, and relationships. You choose how many cards to generate.

3
Review and save

Check the generated flashcards, edit anything you want, then save to your library. FSRS v6 schedules your reviews for optimal long-term retention.

Lecture slides

Download your professor's slides, upload the PDF, and get a study deck in seconds. No more manually copying key points from 80-slide presentations — AI does the extraction for you.

Textbook chapters

Upload a chapter and get flashcards for every important concept, definition, and relationship. Perfect for exam prep when you need to cover material efficiently.

Course syllabi and study guides

Law students: upload your case briefs. Language learners: upload your grammar guides. Any structured document with concepts worth remembering works as input.

Built for students

Most flashcard apps make you type every card by hand. Forgetless reads your existing study materials and generates cards from them. Upload the documents you already have — slides, notes, guides — and start studying in minutes instead of hours. Free users get 3 PDF uploads per month.
