ZOHAL

Zohal is calculus practice the way you'd actually do it: on paper. Pick a problem, or circle one from your own PDF worksheet, and start writing with Apple Pencil or your finger. Zohal reads your handwriting as real math — not just the final answer, but every step along the way. -------- Terms of Use: https://zohal.ai/terms Privacy Policy: https://zohal.ai/privacy When you get stuck or make a mistake, Zohal notices. It won't hand you the answer right away. It'll point at the step that's off, ask a question, or give you a hint — the same way a good tutor would, one nudge at a time. WHAT YOU CAN DO - Solve on an infinite handwritten canvas - Practice hundreds of verified calculus problems, from limits to Taylor series - Import a PDF and circle any problem to work on it - Get step-by-step feedback as you write, not just a final grade - Track your progress chapter by chapter and pick up where you left off Zohal is built for people who think better with a pen in hand. No typing equations into a box, no switching between five apps to check your work — just you, the problem, and a tutor watching over your shoulder. Calculus I is where we're starting. More is coming.
