About
A tutor in every student's pocket.
Revision Genie is built in the UK by a small team who think every student deserves the kind of one-to-one help that's usually reserved for the lucky few. This is the story of why.

A student sits down on a Sunday night to revise. They get stuck on a past paper question. It's 10pm. They have three options: wait until tomorrow and hope a teacher has time, type the question into a generic AI that doesn't really know their exam board, or give up and scroll on their phone instead. None of those are good answers.
The closest thing we have to a fix is private tutoring. It works, and there's a reason wealthier families pay for it. But it costs forty to sixty pounds an hour, and for most households that's not a real option. The gap that creates between students who can afford one-to-one help and students who can't is huge, and it's growing.
We built Revision Genie because we thought AI could close that gap, but only if it was done properly. Not a chatbot that hallucinates the wrong syllabus. Not a notes-dump that students scroll past. Something that actually knows your exam board, marks your answers against the real mark scheme, and walks you through the bit you got stuck on in plain words, at your own pace, as many times as you need.
What we're trying to do
The simplest way to put it: we want every student in the country to have a patient, knowledgeable tutor sitting next to them whenever they revise. Not instead of their teachers, but alongside them. Teachers are brilliant at the parts that matter most, but they can't be there at 11pm the night before a mock. That's the gap we're trying to fill.
Everything we build comes back to that. The AI tutor explains things in the way your textbook should have. The exam practice gives you the same kind of questions you'll actually sit, and marks them properly. The lessons adapt to what you already know, so you're not wasting time on what you've already got.
What we won't do
We'll never be a tool for cheating. Our AI explains and challenges, it doesn't hand over answers without the working. If your goal is to copy-paste a finished essay, we're the wrong product. If your goal is to actually understand the material, we're built for you.
We won't lock the basics behind a paywall either. The free tier is genuinely useful. We'd rather every student have a tutor than a few have a perfect one. The paid plan exists for people who want unlimited use and the extra features, not because we're trying to gate the core.
And we take safeguarding seriously. We're UK-based, GDPR-first, and we've thought hard about how chat with an AI should work when the user might be a thirteen-year-old. Schools and parents can ask us anything about how it works and we'll answer honestly.
Who's behind it
Revision Genie was started by Corey Cross. Before teaching, he spent years as a software developer working on international projects. The kind of work where the code has to actually hold up under real users in different countries, not just demo well in a pitch deck. He moved into teaching because he wanted to do something that mattered more day-to-day, and ended up in front of a computer science classroom.
He's still there. Corey is a practising CS teacher and kept seeing the same thing in his own students. Kids weren't struggling because they couldn't do it, they were struggling because they didn't have anyone there at the moment they got stuck. He built the first version of Revision Genie on nights and weekends until it was good enough to put in front of his own classes, and he's kept building it alongside them ever since.
That combination matters more than it sounds. Most ed-tech is built by engineers who haven't taught in years, or by teachers without the software background to ship something that actually works at scale. Corey is in a classroom every week, marking real books, teaching real students, watching what does and doesn't land, and he writes the code himself. When something on the platform isn't working, he sees it the next morning in his first lesson.
“Learning is the moment a student stops doubting themselves and starts believing they can do it. Our job as teachers is to help students feel capable, even when something seems difficult at first.”
That belief is baked into how the product works. The AI isn't there to do the work for you; it's there to keep you going when the work feels too hard to start. Every quiz, every lesson, every piece of feedback is written with that in mind.
There's a perception that comes with running a tech company: that we're a hundred people in a glass office somewhere, that someone here is driving a Porsche, that there's a villa involved. We're flattered, but no. There are a handful of us. The car situation is more “reliable hatchback”. The office is wherever the wi-fi is decent that day.
We're a small team and we wear every hat. We write the code, run the servers, answer the support emails, design the lessons, and pick up the phone when a school calls. There's no outsourced support desk and no anonymous help inbox. If you email us, one of us reads it.
For the things we're not personally experts in, we lean on people who are. We work with practising teachers and subject specialists across GCSE and A-Level to cross-reference our content, sense-check our explanations, and flag anything that doesn't match how a topic is actually taught or examined. The AI does the heavy lifting; the humans make sure it's right.
If you spot something we could do better, you can and a real person will read it.
Try it
The honest way to see what we're about is to use it. It's free to start and you don't need a card. Make an account here, pick your subject and exam board, and ask it a question. If it helps, tell a friend. If it doesn't, tell us why.
