This product was not featured by Product Hunt yet. It will not be visible on their landing page and won't be ranked (cannot win product of the day regardless of upvotes).
Solve STEM problems from your course PDFs by hand. Zohal reviews your math steps, points to the first line worth revisiting, and gives a small hint to help you continue.
While studying, I kept jumping between three tabs: the AI, the textbook, and my notebook. The AI would just give me the answer, and I’d lose the thread of what I was actually trying to learn. I wanted one place where I could work through a problem by hand and get help only when I needed it.
That’s Zohal. You pick a problem (from the library, your own PDF, or pasted from anywhere), solve it by hand, and press Review. Zohal reads your handwriting, points to the first step that went wrong, and gives you the smallest hint to keep going. The full solution is there, but you have to choose it.
It covers calculus, differential equations, statistics and physics, in English and Arabic, on the web, iPad and iPhone.
I’d love to know: did the review catch the right step for you? And what topics should we add next?

Hi Product Hunt
While studying, I kept jumping between three tabs: the AI, the textbook, and my notebook. The AI would just give me the answer, and I’d lose the thread of what I was actually trying to learn. I wanted one place where I could work through a problem by hand and get help only when I needed it.
