# Periplus

> Periplus is a learning platform that turns any topic into a personalized course. Start with a question, and it generates full documents, quizzes, and flashcards as you explore — every document links onward to related topics, and everything you read is organized into a personal library with spaced-repetition review.

Periplus is built for curiosity-driven learning: instead of following a fixed curriculum, you explore a connected graph of documents that grows around your interests. Courses decompose a topic into a structured learning path where each node comprises complete documents. Documents can contain interactive maps, math, quizzes, and flashcards; anything you want to remember goes into spaced repetition.

Plans: a free tier (limited documents, flashcards, learning paths) and a Premium tier with PDF grounding, unlimited courses and chat, and images in documents.
