Jungle

Jungle is an AI-powered study platform for students that generates flashcards and quiz questions from existing learning materials in seconds.

Key capabilities include:

• Auto-generation from many sources: Upload lecture slides, PDFs, PowerPoint, webpages, YouTube videos, textbooks, study guides, and notes to extract key concepts and create practice questions.
• Multiple question formats + feedback: Create multiple choice, free response, and case questions, then get personalized feedback to understand what was correct or incorrect.
• Spaced repetition and progress tracking: Review weak topics using a spaced repetition system (similar to Anki) and track learning with a gamified Jungle tree.
• Chat with materials: Ask questions about uploaded documents and videos, with AI explanations and support for multiple languages.

Pricing: Freemium. Free plan includes 10 generations per month (limits on pages, video minutes, and advanced question types). Paid tiers include Super Learner ($12/month or $72/year).

Notable for combining rapid question generation with instant answer feedback, document chat, and Anki export, plus availability across Web, iOS, Android, and a browser extension. Used by over 1 million students.
