Answers AI is an AI homework solver and tutor. You snap a photo or paste a question across subjects and get answers and step-by-step explanations, plus notes and summaries from its Lecture Mode.
See it on your own lecture. It takes about a minute.
Yes, if you want a tool built around your whole course instead of one question at a time. StudyPDF grounds every answer in your own uploaded files, cites the page, writes full graded exams, exports to PDF, and to Anki on Pro, and tracks per-concept mastery. Answers AI is better when you just want to snap a photo of a problem and get a quick answer.
What does StudyPDF do that Answers AI doesn't?
It grounds answers in your own course files and cites the page behind each one, refuses to make things up, maps your whole course into one connected concept graph, writes full graded practice exams, exports flashcards to fold-over PDFs, and to Anki on Pro, builds mind maps and cheat sheets, and tracks per-concept mastery so it knows what to study next.
What does Answers AI do that StudyPDF doesn't?
Answers AI lets you snap a photo of a single homework question and solve it instantly across many subjects, with no upload needed, on mobile, web, and a Chrome extension.

How much does StudyPDF cost?
It is free to start, and Free gives you about 4 materials a week. Pro and Ultra add a bigger weekly pool of credits for heavier exam-season use. You only upgrade when you outgrow the free plan.
