Questions
Do I need Claude or ChatGPT?
No. Sayo works on its own on the web, with the same courses, flashcards and quizzes. Claude and ChatGPT are another way in, using the same account.
What can Sayo teach me?
Most subjects you'd learn from a book or a course: sciences, languages, history, economics, programming and more. Tell it your goal and what you already know. If a topic is too broad, Sayo asks you to narrow it down.
Can I record my lectures?
Many schools allow recording for personal study, some don't. Check your school's rules and ask your lecturer when in doubt. Sayo keeps recordings private to you.
What happens to my audio?
It's turned into a transcript and your study material. Raw audio is deleted once processing is done, and you can delete your account and everything in it in one tap.
Which languages work?
Recordings can be in over 90 languages. Lessons, notes, quizzes and voice work best in English, Spanish, Portuguese, French, German, Italian and Hindi.
Is it free?
Your first course is free: the first three lessons of a topic Sayo teaches, or one lesson of your own. After that it's a subscription with a free trial.
