Side by side with ChatGPT
Both can explain anything. Here's what you get on top of the explanation.
Periplus- Lays out the whole course for you, chapter by chapter
- Quizzes and exams test you as you learn, so gaps show up early
- Flashcards bring ideas back right before you would forget them
- Maps, diagrams and images inside the lesson
- Everything you've learned sits in one library, and new courses pick up from there
- Makes you the teacher: you decide what to learn and in what order
- You read the answer and move on. Nothing checks whether it stuck.
- 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
