for every unit
Short walkthroughs embedded next to the lesson they cover.
What teachers do with it.
Three of the things teachers use Perplex for, week to week.
A student interface they actually open
Animated walkthroughs, draggable graphs, embedded videos. Lessons that feel closer to a YouTube explainer than a worksheet.
Assigned work without the busywork
Choose your problems, set a due date, and publish. Perplex handles versions, attempts, marking, and reminders so you can get back to teaching.
Practice sets that respect what you've taught
Build cumulative test prep in a few minutes. Filter out anything you haven't covered, schedule release and end dates, and reuse next year.
Try it. Like it. Then we'll talk.
You and your class can start using Perplex for free. Add your students, assign a few pieces of work, build a practice set, and see how they get on with it. If it becomes a real part of how you teach, get in touch and we can have a sensible conversation about pricing for your school, on a timeline that fits your budget cycle.
For department heads & admins
Bringing Perplex to your department.
Syllabus-aligned content
All of our problems, lessons, and walkthroughs are written in-house by our team, and mapped directly to the syllabus. We cover both AA and AI, at SL and HL.
Flexible pricing
Annual licences, billed at the start of your school year. Most departments begin with a free pilot and only commit to a paid plan once they have seen how their students get on with it.
Privacy and security
We follow GDPR, never show advertising to students, and do not sell their data. We are happy to share our Data Processing Agreement with your school before any contract is signed.

From there, we'd love to hear from you. Most of what is in Perplex started as a request from a teacher using it. If something is missing, broken, or just bothering you, send us an email and we will usually have it fixed within the week.
