Oscelyra

Oscelyra turns OSCE revision into something you actually do out loud. Pick a station, read the candidate instructions, and talk to a simulated patient the way you would in the exam — by voice or by typing. When the clock stops, your consultation is marked against that station's mark scheme, and every mark you earned links to the exact moment in your transcript that earned it. PRACTISE OUT LOUD Speak naturally and the patient answers naturally. They give you what a real patient gives you: an opening line, and then only what you ask for. If you never ask whether the pain radiates, you never find out. MARKED, NOT JUST CHATTED WITH Each station has a written mark scheme. You get a percentage, a domain breakdown — history, communication, clinical reasoning, management, safety — and a plain list of what you missed. Critical items are called out separately, because in a real OSCE they are what fails you. SEE WHERE THE MARK CAME FROM Tap any earned mark and jump straight to the sentence in your transcript that earned it. Compare your attempt with a distinction-level model answer for the same station. 53 STATIONS AND A BUILDER Fifty-three stations across general practice, emergency medicine, cardiology, neurology, gastroenterology, paediatrics, psychiatry, obstetrics and gynaecology, ethics, and more. Eleven emergency stations deteriorate while you consult, so what you do next actually changes the patient in front of you. Need something specific? Build a custom station (beta): choose the presentation, focus and difficulty, and practise it minutes later. KNOW WHAT TO PRACTISE NEXT Oscelyra tracks the marks you keep missing across stations and turns them into a readiness picture: your strongest and weakest domains, stations due for spaced review, and a weekly goal. Set your exam date and it counts down with you. FREE EVERY MONTH The Daily Station — the same case for every student, every day — is free forever, offline practice with scripted patients is unlimited, and you get 5 AI-marked stations every month. No account needed. OSCELYRA PRO For the final stretch: 150 AI-marked stations and 30 custom case generations a month, on a monthly or 3-month plan. Create a free account and your practice history and streak follow you across devices. Subscriptions renew automatically until cancelled in your App Store settings. IMPORTANT Oscelyra is educational software. Every patient in it is simulated. It is not a medical device, it gives no medical advice, and it must never be used to diagnose, treat, or make decisions about a real patient. Scores are study feedback generated in part by AI — they are not an examiner's verdict and do not predict your result in any real examination. Always follow your medical school's and regulator's guidance. Oscelyra is designed around OSCE-style clinical exams, including the PLAB 2, UKMLA CPSA and NAC OSCE formats. It is not affiliated with, endorsed by, or connected to the GMC, the Medical Council of Canada, or any examination board, medical school, or regulator. Accounts are optional; without one, your practice history stays on your device. No adverts.
