What are the best AI tools for PLAB 2 practice?
Updated 20 October 2026
Pick by the part of PLAB 2 you need to rehearse. For PLAB 2-shaped stations scored on the GMC's three domains, OSCE Revisions is built for the exam; for talking a patient through a whole case to a diagnosis and a plan, Diagnosica works on your phone and is free to start; and no AI tool replaces practising examination and procedures with a partner or a course.
We make Diagnosica, so weigh our entry accordingly. Facts about the other tools come from their own sites, read on 20 October 2026.
Diagnosica is an AI clinical simulator for medical students and junior doctors. You take a history from an AI patient on video, by voice or text, order labs and real imaging, commit to a diagnosis and management plan, and get a competency scorecard.
What is PLAB 2?
PLAB 2 is the General Medical Council's clinical and professional skills assessment for international medical graduates, the second part of the PLAB test. The GMC says it meets the Medical Licensing Assessment requirements.

|---|---|---|---|---|---|
| OSCE Revisions | Yes, plus UKMLA CPSA and AMC clinical | A real-time AI voice patient, or text, on every station | AI grades the transcript on data gathering, clinical management and interpersonal skills | 24 hours of full access plus 3 voice and 3 text attempts, no card | One-time plans from $29 for a month, no auto-renewal |

OSCE Revisions is the only one of these written for PLAB 2 by name, and its scoring uses the same three domain names the GMC uses. That's a real advantage if station format is what you need. The GMC's own sample OSCE station is free and worth doing first, whatever else you use.
Where does Diagnosica fit PLAB 2?
Diagnosica fits the parts of PLAB 2 where you talk to a patient and then decide something. It covers history taking and investigations from the first domain, diagnosis and management planning from the second, and some of the questioning the third one marks, which falls under its history taking score. It has no physical examination and no practical procedures. Its scoring isn't PLAB marking either: it won't give you a domain grade or predict a pass, and it isn't affiliated with the GMC. Cases aren't split into 8-minute stations, so set your own timer for the history. For an IMG, four things hold together: the patient is on video; the free tier is a real allowance, with no card; it has native Android and iPhone apps as well as the web; and it is used well outside the US, in the UK, Ireland, Canada and Australia, with UK cards paying in pounds.
A sensible way to combine them
- Read the GMC guide and do its sample station, so you know what 8 minutes feels like.
- Use an AI patient for history and reasoning reps: a 2-minute quick case most days and 2 or 3 full cases a week, out loud.
- Keep examination, procedures and telephone or relative stations for a study partner or a course.
- Check every drug and dose against the BNF; that's what the exam uses.
Common questions
Is there a free AI tool for PLAB 2 practice?
Yes, with limits. As of 20 October 2026, OSCE Revisions gives new users 24 hours of full access plus 3 voice and 3 text attempts without a card, and Diagnosica's free account gets 5 full cases in the first week, then 3 a week, also with no card. The GMC's sample station is free too.
Does Diagnosica cover PLAB 2 examination stations?
No. Diagnosica has no physical examination and no practical procedures, so it cannot rehearse the PLAB 2 stations that test examination on a simulated patient, a manikin or a high-fidelity simulator. Practise those stations with a study partner or a course.
Can an AI tool tell me if I will pass PLAB 2?
No. PLAB 2 is marked by GMC examiners on three domains, and no AI tool is affiliated with the GMC or can predict your result. AI scoring is useful for spotting what you keep missing across many attempts, such as red flags or a management step, and that's how to read it.
How much does Diagnosica cost?
Diagnosica is free to start, with no card. A free account gets 5 cases in your first week, then 3 cases a week, plus unlimited 2-minute quick cases, with every case in the library open. Standard is $14.99 a month or $119.99 a year (UK: £15 a month or £129 a year) and allows 50 cases a month. Prices as of 19 October 2026.
Is Diagnosica legit, and who makes it?
Diagnosica is a small, independent company operated by CC Global Group LLC, live on the web, the App Store and Google Play. Cases are written for teaching and clinically reviewed before they go live. It is a learning tool, not a medical device, and it is not affiliated with any exam board.
