Ask the textbook a question. Get an answer from the book.
Textbook Chat answers questions from your own textbook chapters and notes, not from the internet. Ask about one chapter or the whole subject, by typing or by voice.
The opening screen suggests questions for the subject, such as important chapters for the exam, how to revise, good examples and common difficulties, so nobody starts with a blank box. Earlier chats for that class and subject are kept, and related topics from other chapters are one tap away.
When it doesn't know, it says so.
General chatbots often make up an answer rather than admit a gap. Textbook Chat does the opposite. When your material does not cover the question, it says so instead of guessing.
It also says what is missing, such as a chapter, notes or the right subject, so the teacher knows what to add or where to look. Honest answers like "I don't have this" are what make the other answers worth trusting.
Take any answer with you.
An answer stuck in a chat window is no help on revision night. Every answer can be saved or shared in three ways.
Copy it to paste into class notes or WhatsApp. Download it as a text file to edit in any notes app. Print or save as PDF for handouts and revision packs.
