Jungle is an AI study tool that generates flashcards and practice questions from course material, founded by CEO Julian Alvarez and CPO David Glass, who launched the product in early 2023 under the name Wisdolia before rebranding to Jungle. The company is based in Palo Alto, California.
Students upload lecture slides, PDFs, PowerPoints, textbooks, or a YouTube video link, and Jungle generates flashcards, multiple-choice questions, and case-scenario questions directly from that material, then runs spaced-repetition review sessions similar to Anki. A specific feature worth noting is AI image occlusion, which turns diagrams and labeled images into interactive cards automatically instead of requiring manual masking, and a chat mode that lets students ask follow-up questions against the source document when a generated card is unclear.
Jungle is built for students preparing for exams, with a user base the company puts over 1 million, skewing toward medical and other credential-heavy programs. The free plan covers 10 generations per month across 30 pages per document or 30 minutes of video; the paid Super Learner plan runs $12 per month (or $6 per month billed annually) and removes those caps along with adding unlimited AI explanations and Anki export.
