Grademy vs Medly AI: which AI study tool fits how you revise?
An honest, respectful comparison of Grademy and Medly AI for GCSE and A-level, covering marking, course sources and pricing, so you can pick the right fit.
Both Grademy and Medly AI mark exam-style answers and explain the feedback, and both are built for UK exam students rather than general homework help. The main difference is where the study material comes from: Grademy builds everything from the course files you upload, while Medly gives you a ready-made library matched to your exam. Neither is "better" in the abstract, so the right choice depends on how you actually like to revise.
This is a fit-based comparison, not a takedown. Medly is a credible, well-funded product, and where we could not verify something about it, we say so rather than guess.
What is Medly AI?
Medly AI describes itself as an AI study partner for GCSE, A-Level, IB, AP and SAT. It was founded by NHS doctors, and its marketing leads with "your marks, explained," which is the same core promise as Grademy: practice questions built like real exams, then instant marking with feedback.
As of July 2026, Medly's UK pricing is £24.99 a month, or £80 as a one-off payment to the end of the academic year, and it is free to start with no card required. Medly is also clear about its pedagogy: it positions itself against answer-giving AI, stating it will not write entire essays for you and will instead guide you to the answers. That trust stance is worth calling out, because Grademy takes the same position.
We are date-qualifying these facts on purpose. Pricing and feature sets change, so check both sites for the current details before you decide.
What is Grademy?
Grademy is an AI tutor for UK GCSE and A-level students. It marks your answers like an examiner, explains every mark, generates exam-style practice from your own course materials, and plans revision around your exam dates.
The distinctive part is the source of the content. Instead of studying from a fixed library, you upload your own course: your class notes, your exam board specification, and your past papers. Grademy then builds lessons, practice and marking around that specific material, so the questions look like the ones your teacher and exam board actually set.
How do Grademy and Medly compare?
| Dimension | Grademy | Medly AI (as of July 2026) |
|---|---|---|
| Audience | UK GCSE and A-level | GCSE, A-Level, IB, AP and SAT |
| Marking approach | Examiner-style marking that shows its reasoning mark by mark | Instant marking with feedback, described on their site as "your marks, explained" |
| Where content comes from | Generated from your own uploaded notes, specification and past papers | A ready-made library matched to your exam |
| Pedagogy stance | Guides you to the marks, does not do the work for you | States it guides you to answers and will not write entire essays for you |
| Pricing model | See grademy.work for current pricing | Free to start; £24.99 a month or £80 to the end of the academic year |
| Revision planning | Plans revision backwards from your exam dates | We could not verify a dated revision planner on their consumer page |
A note on that last row. Medly's UK teacher page describes classroom features like a topic-level mastery heatmap and engagement trends, but we could not verify a student-facing revision planner tied to exam dates from the research available to us, so we are not claiming it lacks one. If that feature matters to you, confirm it directly.
Which one should you choose?
Here is the honest way to decide, based on how you revise.
Choose Medly if you want a ready-made library
If you would rather open an app and immediately have exam-style questions waiting, matched to your subject, Medly's model suits you well. A fixed, curated library means less setup. You do not have to gather your notes or upload anything before you start practising. The breadth also helps if you sit exams beyond the UK system, since Medly covers IB, AP and SAT alongside GCSE and A-Level. If a low-friction start and wide coverage are your priorities, Medly is a strong fit.
Choose Grademy if you want to study from your own course
If your revision works best when it mirrors your actual class, Grademy's model fits better. Because everything is generated from the notes, specification and past papers you upload, the practice reflects your exam board's wording and your teacher's emphasis rather than a generic version of the subject. That matters most when the gap between "knowing the topic" and "getting the marks" comes down to exam-board-specific phrasing.
Grademy also leans hard into showing its working. When it marks an answer, it explains each mark: which points earned credit, which phrase fell short, and what the mark scheme wanted instead. That is deliberate, because an AI marker can be wrong, and a tool that shows its reasoning is one you can actually check and challenge. If you want feedback you can interrogate, rather than a score you have to trust, that transparency is the reason to pick Grademy.
Where the two overlap
It is worth being clear about the common ground, because it is real. Both tools mark exam-style answers and explain the feedback. Both take an explicit stance against doing the work for you, and both frame their AI as a guide to the marks rather than an answer machine. If you agree with that philosophy, you will feel at home with either product. The decision comes down to the library-versus-your-own-materials question and how much you value seeing the marking reasoning laid out.
The honest bottom line
Medly is a legitimate, capable product with broad coverage and a low-friction free start, and for a lot of students it will be the right tool. Grademy is built for a specific way of working: revising from your own course, and getting marking you can see the reasoning behind, planned around the dates you actually sit your exams.
If that description sounds like how you want to revise, you can try it at Grademy. If it does not, Medly is a fair alternative, and there is no shame in picking the one that fits your habits.
