How it works
One assignment, minus the tangled thread
A general chatbot mixes every question together. Puno keeps each problem's context where it belongs.

01
Ask or upload
Type a question, paste problems, or drop a PDF or screenshots of the whole assignment.

02
Review the split
Puno detects each problem for you to confirm, edit, or turn into a practice set.

03
Chat per problem
Every problem gets its own focused thread — follow-ups never drag the rest along.
Built for learning
A tutor, not an answer machine
Puno explains the reasoning behind every step — so the next problem is easier than the last.
Highlight to ask
Select any line in an answer to ask about exactly that part — quoted straight into your follow-up.
Photo step-check
Snap your worked attempt and Puno finds the exact step where it went wrong.
Practice on demand
Turn any assignment into a similar practice set to drill before the test.
Math that reads right
Fractions, integrals, and matrices rendered beautifully — never plain-text soup.
FAQ
Questions, answered
Is Puno free?
Yes — the free tier covers daily homework help with per-problem chats and practice tests. Pro ($12/mo) is there when you need way more usage and frontier models.
Which subjects does it cover?
Math from algebra through calculus, plus chemistry, biology, essays, and more. If you can type it or photograph it, you can ask about it.
Does Puno just hand me answers?
No — it works like a tutor. You get the reasoning behind each step, your mistakes get pinpointed from a photo of your work, and practice sets make sure it sticks.
Do I need to install anything?
No. Puno runs in your browser — sign in with Google and start from a blank page.
Can I cancel Pro anytime?
Yes. Manage or cancel your subscription from the billing portal in one click; you keep Pro until the period ends.
