About Ask Lessi
Is Ask Lessi free?
Yes, with a free account, and no card is needed. Time chatting with Lessi comes from the same free minutes as lessons, and it only counts while you are chatting. Your chats are saved, so you can come back to them.
What can I ask?
Any question about school or university work, in any subject: a maths problem, an idea in science, a grammar rule, an event in history. Lessi answers simply, step by step.
Can Lessi help with my homework?
Yes. Lessi explains how to solve the question, step by step, so you can do the next one yourself. When this site has a full lesson on the topic, a link to it appears under the answer.
Are the answers always right?
Not always. The answers are written by AI and can contain mistakes, so check anything important against your textbook or your teacher.
Is it suitable for children?
Every question is checked before it is answered, and a question that is not suitable gets no answer from the AI. Lessi does not give medical or legal advice.
How is a question different from a lesson?
A question gets one answer. A lesson with Lessi teaches a whole topic, with a board, a voice and short quizzes, at your pace. The first 60 minutes are free with an account.
Asking needs a free account; your question is kept while you sign up. Answers are written by AI and can contain mistakes. Lessi doesn’t give medical or legal advice.
