Not another AI chatbot
There are hundreds of AI tools. Here's what makes Periplus different from a chat window.
Periplus- Plans a whole course structured for you, based on learning science
- Quizzes and exams test you as you learn, so gaps show up early
- Flashcards bring ideas back right before you would forget them
- Interactive visualizations, images
- All courses wait in one library, and personalize the next
- Makes you the teacher: you decide what to learn and in what order
- Reading feels like understanding, but has no active recall
- What you read today fades by next week, and you lose the chat
- A wall of text in a chat box
- Your learning ends up scattered across old chats you can't find
