iChatbook vs Mathos AI (formerly MathGPTPro)

iChatbook is a book library platform where you browse pre-indexed titles, read AI summaries at four depth levels, and chat with individual books or across your whole reading list. The catalog covers thousands of published works with no PDF uploads required for library titles.

Beyond passive summaries, iChatbook adds active recall quizzes, fill-in-the-blank tests, and spaced repetition to help you retain what you read. Cross-book chat lets you ask one question and pull answers from multiple authors, surfacing agreements and contradictions across sources.

An authoring workspace called Originals turns voice memos, slide decks, and essays into publishable books. You get three-voice draft generation, inline citations pulled from the library, and reader pages you can publish and sell. Plans split between free exploration, a $25/month Pro Reader tier, team seats, and a separate Originals subscription for writers.

Mathos AI is an education math solver and tutor that turns a photo, typed equation, or word problem into step-by-step solutions, quizzes, flashcards, and animated lesson videos. One prompt can branch into a worked answer, a 5 to 10 second video first frame, practice cards, and an adaptive review path when you miss a concept.

Generic chatbots hand back a final number with little scaffolding. Mathos breaks problems to their core, repairs the prerequisite you missed before repeating the topic, and the AI Tutor watches your whiteboard steps to catch errors at the exact line where reasoning breaks. The company reports 5 million students and 100 million problems solved.

High school and college students use it for calculus, algebra, and physics homework, while parents get session summaries through a dashboard. The product is free to start with a 3-day trial on paid plans, and an enterprise video API tier offers 3,800 generated minutes per month.
