If you are weighing up a Medibuddy alternative in 2026, you are comparing two platforms with a similar philosophy. Medibuddy is an AI-powered, adaptive question bank for the UKMLA, the MSRA, PLAB and MRCP Part 1, with a "mastery" model and a toggle between adaptive and traditional modes. iatroX shares the adaptive approach but adds a Socratic tutor and clinical AI, keeps its core banks free and the rest low-cost, and covers far more of a medical career. This guide compares the two fairly — including where Medibuddy, the closest like-for-like option, does things iatroX doesn't.
What Medibuddy is, and why doctors use it
Medibuddy is an AI-powered, adaptive UK question-bank platform built by junior doctors, covering the UKMLA AKT (4,000-plus questions), the UKMLA CPSA (with 145-plus OSCE stations), the MSRA (4,000-plus questions), PLAB and MRCP Part 1. Its model is genuinely adaptive: questions you get wrong are re-asked to build a "mastery" level per topic, and you can switch between an adaptive mode and a traditional filterable mode, with answers from either feeding your mastery score. Its content is mapped to the MLA content map, with detailed explanations and a mobile app. Its appeal is a polished, single-purpose adaptive experience for its core exams, including CPSA and OSCE coverage. Of all the platforms an iatroX user might compare, Medibuddy is the most philosophically similar: both are built on the idea that an algorithm should decide what you see next, rather than handing everyone the same fixed list. That shared starting point makes the comparison less about whether adaptive learning helps — both assume it does — and more about coverage, price and the depth of feedback.
How iatroX compares
iatroX is also adaptive, and built around five things: a Socratic tutor that works back through the reasoning behind a wrong answer; questions mapped meticulously to each exam's blueprint; spaced repetition; a genuinely adaptive engine that targets your weak areas; and native iOS and Android apps. The differences are coverage, price and tools: iatroX keeps MRCP, MRCEM, the PSA and PARA free — and puts the MSRA, PLAB, UKMLA and the MRCGP AKT on a £29/month or £99/year subscription, and it adds clinical AI guideline lookup and calculators. It also covers exams Medibuddy doesn't, including MRCEM, the PSA, diplomas, the SCEs, the GPhC assessment and international boards. In short, the two overlap most on the UKMLA, the MSRA and PLAB, where both are adaptive; they diverge on everything around those exams, where iatroX is free, broader and paired with clinical tools. For a student focused only on finals, the gap is narrow; for a doctor thinking past them, it widens quickly.
The honest comparison
| iatroX | Medibuddy | |
|---|---|---|
| Price | Core free; rest £29/mo–£99/yr | Paid subscription |
| Adaptivity | Adaptive engine plus a Socratic tutor | Adaptive "mastery" model; adaptive/traditional toggle |
| OSCE / CPSA | Not covered | Covered (145+ stations) |
| Coverage | UK core, diplomas, GPhC, US/CA/AU | UKMLA, MSRA, PLAB, MRCP Part 1 |
| Extras | Clinical AI lookup, calculators | Per-topic mastery dashboard |

Where iatroX wins
Price for most exams is the headline: MRCP is free on iatroX, the MSRA and PLAB are on a low-cost subscription, and Medibuddy is paid throughout. The Socratic tutor is the other real difference — it works back through the reasoning behind a miss, rather than re-asking the same question until it sticks, which is a deeper form of feedback. And the breadth is wider: it covers MRCEM, the PSA, the SCEs, diplomas, GPhC and international exams that Medibuddy doesn't, with clinical AI and calculators alongside. The pricing point is not a trial tier or a teaser: MRCP is fully free, and the MSRA and PLAB sit on one low-cost subscription, so the adaptive experience you are comparing is cheap to access for the exams Medibuddy charges separately for.
Where Medibuddy wins
Medibuddy's CPSA and OSCE coverage is a genuine advantage: its 145-plus stations for the clinical side of the UKMLA are something iatroX's written question bank does not provide. Its adaptive-and-traditional toggle is a neat piece of design, letting you switch between guided and self-directed revision while keeping one mastery score. And it offers a polished, single-purpose adaptive experience focused tightly on its core exams. For the UKMLA specifically, having the written and clinical sides under one adaptive roof is a real convenience, and it is the clearest reason a finals student might choose Medibuddy as their single platform.
When Medibuddy is the smarter choice
If you want CPSA and OSCE coverage alongside an adaptive AKT bank for the UKMLA, Medibuddy covers both sides of that exam in one place. And if you prefer a single, tightly focused platform for the UKMLA, the MSRA, PLAB or MRCP Part 1 and do not need broader coverage, it does that job well.
How to choose
If you are sitting MRCP, iatroX's bank is adaptive with a Socratic tutor; for the MSRA or PLAB it is a low-cost adaptive option, so start there either way. If you need CPSA or OSCE practice for the UKMLA, Medibuddy covers that and iatroX does not. And if you are sitting several exams over a career, or want clinical AI tools, iatroX covers far more, with MRCP, MRCEM, the PSA and PARA among it free.
A few common questions
Both are adaptive — what is different? iatroX adds a Socratic tutor and clinical AI, keeps its core banks free and the rest low-cost, and covers far more exams; Medibuddy adds CPSA and OSCE coverage and an adaptive/traditional toggle.
Is iatroX free? MRCP, MRCEM, the PSA and PARA are free; the MSRA, PLAB, the diplomas, the SCEs and international are on one subscription at £29/month or £99/year.
Does iatroX cover the CPSA or OSCE? No — that is a Medibuddy strength; iatroX focuses on written and SBA exams plus clinical AI.
Can I use both? Yes — iatroX for adaptive MSRA, PLAB or MRCP practice, Medibuddy for CPSA coverage.
