Every STEM student knows the feeling: you open a problem set, stare at question 4, and realize the textbook example skipped the exact step where you get stuck. You go to the back of the book and the "solution" is just a final number with no working. Brilliant.
iTutor's new Worked Solutions generator fixes that. Upload your textbook or problem sheet, pick the topic, and get fully explained step-by-step solutions to every problem the AI finds — including the narrative reasoning for each step, the final answer, and a common-pitfall note telling you where students usually blow it.
From your book, not a random website
This is the part that matters. There are dozens of generic math solvers online. They'll happily produce an answer that uses a technique your course never covered, or notation your professor doesn't use. When iTutor solves a problem, it has already read the chapter the problem came from. The solution stays in the method and vocabulary your class is actually using.
If the extractor can't find enough problems in your material, it generates new ones modelled on the source's difficulty and style, then solves those in full. Either way you end up with a clean worksheet plus a separate solution key you can print.
What one solution looks like
Every problem comes with: the statement, the givens, what you need to find, a numbered list of solution steps with narrative + math on each line, the final answer, and a common pitfall. Math renders with KaTeX so fractions, integrals and matrices look right. You can toggle "show answer only" when you want to self-test, then flip steps back on when you're ready to check your working.
Who gets the most out of it
Physics, chemistry, calculus, statistics, and econ students are the core audience — anywhere problem-solving is the main skill being tested. It's also genuinely useful for teachers building answer keys: instead of hand-writing twenty solutions, generate them, skim for accuracy, and hand them out.
Pair the worked solutions tool with the AI Study Guide (for the conceptual big picture) and the Exam Prep Session (for a simulated TA-led review the night before a test). Those three together cover pretty much every STEM exam-prep scenario we could think of.
Try it
Head to itutor.study, upload a chapter PDF, and click "Generate Worked Solutions" from the planner. The free tier includes enough generations to work through a full problem set — no credit card. If your exam is tomorrow, you're about ten minutes away from a full solution key.
