Derive is the intelligent notebook app for stem, like having a personal tutor in your notes. 

You handwrite on your tablet in Derive, and it understands every line of your working. With real time mistake detection, that catches errors as they’re made, not 30 minutes later, so you can improve fast and stay in the flow instead of erasing and repeating the entire question.

Derive also helps you visualise math with 2D and 3D graphs from equations in a single click. It supports writing and running code in code spaces, and turns your own notes into past paper style practice exams, from the working you have already done.

Drop in lecture slides or a past paper and write straight onto them. Everything syncs across iPad, Mac, Windows and the web, so the notes you take in the lecture are the notes you revise from.

Students get 10% off Derive Pro with the referral code, and the discount lasts for as long as the subscription keeps renewing. Every subscription starts with 7 days free.
