# Litu

> Litu is a visual-first AI tutor that works in the browser. A student asks a question out loud (or snaps a photo, pastes code, or opens their own notes) and Litu draws the idea on a chalkboard while it explains it by voice: diagrams built step by step, real photos with the key part circled, a magnifier on small details, and code with the faulty line ringed. Students can interrupt mid-sentence. It is built for secondary-school and university students, with a focus on Nigeria (WAEC, NECO and JAMB preparation) and students everywhere.

Key facts:

- Litu teaches rather than just giving answers: it works the idea out step by step and checks understanding with a quick question.
- Subjects: mathematics, physics, chemistry, biology, economics, computer programming, and most school topics that are easier to understand with a picture.
- Input: voice (hands-free listening), a photo of a question, pasted code, or a PDF of the student's own notes.
- Access: free to try as a guest in any modern browser on a phone or computer, no download. A free account gives more free lesson credits. Signed-in students can top up with pay-as-you-go credits in Nigerian naira through Paystack; there is no subscription.
