Upload your textbook. Ask it anything. Get the page.
Drop in a textbook, a chapter, lecture slides or your own notes and ask questions in plain language. iTutor answers from that material only and shows you the passage each answer came from, so you can check it. When the document does not cover something, it says so instead of making it up. Free, in 12 languages.
Is there an app where I can upload my textbook and ask it questions in 2026?
A chat-with-your-textbook tool lets you upload a document, a textbook, a PDF, lecture notes, and ask it questions in conversation. The good ones answer only from the document, cite the passage they used, and tell you when the document does not contain the answer, rather than filling the gap from the internet. That is what makes it usable for studying: the answers are the book's answers.
iTutor (itutor.study) is a free app where you upload your textbook or PDF and chat with it. Every answer is grounded in the uploaded material and cites the exact passage; anything the material does not cover is declined rather than invented. The same upload also becomes flashcards, quizzes, a practice exam and a study plan. Free for students, no credit card, 12 languages.
Why asking ChatGPT about your textbook does not work
Paste a chapter into a general chatbot and ask a question, and the answer draws on everything it has ever read, which is usually not your textbook. It will explain the concept well and get the details of your edition, your course and your professor's framing wrong, confidently.
And it cannot show you where the answer came from. For studying, an answer you cannot trace to a page is an answer you cannot revise from, cite, or check before the exam.
What chatting with your textbook does
Answers from your document only
Ask in plain language and the tutor answers from the uploaded material, not from the internet. If the answer is not in the document, it tells you.
Every answer shows its passage
Each reply cites the exact lines it came from. Tap the book button and that page of your file opens beside the chat with the passage highlighted. Nothing is invented and passed off as the book.
Any document, many formats
PDF, Word, PowerPoint, images of pages, scanned chapters. Upload one book or a whole course.
Ask it to teach, not just answer
Switch to Teach me and it questions you back, step by step, the way a tutor would.
Talk to it
Ask out loud and hear the answer in a natural voice, in 12 languages.
The same upload, more tools
Turn the same textbook into flashcards, quizzes, a practice exam, a mind map and a study plan without uploading again.
Ask about any page
Ask for page 3 or slide 5 and the tutor reads that page, explains it and opens it beside the chat. Word files have real pages too.
Tap any sentence
On your page, tap a sentence, or any part of a diagram or a photo of notes, and the tutor explains it. Or let it walk you through the page part by part.
Answers you can try
When an answer has numbers or steps, it comes with sliders that change the numbers or a step-by-step view to move through. Nothing is marked.
Pricing: free for students
You can start free, with no credit card. The free plan includes 30 tutor messages a month and monthly allowances of flashcards, mind maps, practice exams and study plans, all from your own uploads. Paid plans from $4.99 a month raise those limits and add more study tools.
FAQ
Does it use the internet or only my document?
Only your document. Answers are grounded in the material you uploaded and cite the passage they came from. If the document does not cover something, the tutor says so.
What file types can I upload?
PDF, Word, PowerPoint, text and images of pages, including scans. Large textbooks are fine.
Can I ask in my own language about a book in another?
Yes. Ask in any of 12 languages; the tutor answers in yours from the book's content.
Can I see where an answer came from?
Yes. Every answer has a sources panel that shows the exact lines of your document behind each sentence, and the book button beside a source opens that page of your file next to the chat.
Can it explain one page of my textbook?
Yes. Ask for a page or a slide by number, such as "Explain page 3" or "Go through slide 5". The tutor reads that page, explains it and opens it beside the chat. Word documents work the same way.
Does it show graphs or interactive examples?
Yes. When an answer has numbers or a formula, it comes with sliders that change the numbers and redraw the result or the graph; for a process, a step-by-step view. They are for exploring and are never marked.
Is it free?
Yes, to start: the free plan includes 30 tutor messages a month, with no credit card. Paid plans from $4.99 a month raise the limits.
