Learning tools for GP registrars, built on the evidence for how people learn
The learning techniques with the best evidence take effort: recalling from memory, spacing out your revision, explaining your reasoning and linking new knowledge to what you already know. Mosaic gives you free tools to put them into practice, mapped to the RCGP curriculum. It's about building the knowledge and confidence that real general practice demands, and because the learning is stronger, it helps you through your exams along the way.

What's inside Mosaic?
Each tool is built around a technique with good evidence behind it
Use them together, or pick whichever suits you today.
Flashcards
Spaced retrieval. Testing yourself works better than re-reading, and spacing out your reviews works better than cramming. Flashcards combine the two. How confident you feel, together with a scheduling algorithm (FSRS), decides when each card comes back. You can make your own decks and share them with other registrars.
AKT writing
Generation and self-explanation. Writing an MCQ, and explaining why each wrong option is tempting but wrong, helps you understand a topic properly. AI feedback then checks the quality of your question.
Connection notebook
Connection and reflection. Short prompts help you link new learning to what you already know and to your own patients. They also ask where your thinking has changed, how you'd explain it, and one thing you'll do differently. Over time you build a record across the RCGP curriculum that you can use in your portfolio.
Community
Learn from your peers. Try flashcards and AKT questions other registrars have shared, see how they explained each option, upvote the good ones and talk them through, all in the app.
Concept maps Soon
Mapping what you know. Drawing a map of everything you know about a topic makes you choose what matters and work out how diagnoses, mechanisms, drugs and decisions fit together.
SCA writing Soon
Write, then get feedback, for consulting. Create SCA practice scenarios and get AI feedback on them, the same way AKT writing works.
The approach
Learning by doing
Rereading, highlighting and summarising feel productive, but they come near the bottom when studies compare how well techniques work. The ones that work best take effort. You make something, test yourself on it, and find out what you know. Every Mosaic tool works that way.
The effort is what helps
Struggling to recall the back of a card, write a convincing wrong option or predict an answer you don't yet know can feel like it isn't working. That effort of pulling something from memory is what makes it stick.
Mistakes show up early
When a prediction turns out wrong, or you miss the same card twice in a week, you've found a gap while there's still time to fill it.
Linked to your own practice
New knowledge holds best when it's linked to what you already know. Mosaic keeps bringing you back to your own patients, your education sessions and the RCGP curriculum, so what you learn is organised the way you'll use it. Your dashboard shows how it all fits together.
How it works
How the tools work together
There's no course to work through. You make something, get feedback, come back to it and look for gaps, in whatever order suits your week.
Create
Write an AKT question on a topic you're working on, make flashcards from it, or log a connection from something you've learned this week. Everything maps to the RCGP curriculum and topic guides.
Get feedback
AI review checks your question's clinical accuracy, how it's written and how good the wrong options are, option by option against your own reasoning. If your intended answer is wrong, it tells you. Testing yourself works better when you find out where you went wrong. We remind you throughout that AI can make things up, make mistakes and be out of date, so checking its feedback is part of the learning too.
Revisit on schedule
Flashcards come back just before you'd forget them, spaced further apart each time you get them right. The scheduler decides the spacing, guided by how confident you feel about each card.
See the gaps
The curriculum dashboard shows which topics your questions, cards, and connections actually cover. The gaps show you what to work on next, and the cycle starts again.
The evidence behind the approach
The evidence in brief
The two study techniques with the strongest evidence are testing yourself and spacing out your revision. Mosaic is built around both, plus a few others that suit clinical learning well.
Testing yourself
Recalling something from memory strengthens it more than reading it again. Flashcards and Quick Test both ask you to recall.
Spacing it out
Revision spread over weeks lasts longer than cramming. Your flashcards come back around the time you'd start to forget them.
Explaining why
Explaining why an answer is right, and why the others are wrong, deepens understanding. AKT writing asks you to explain every option.
Connecting and reflecting
Learning sticks better when you link it to what you know and to your own patients, explain it in your own words, and notice where your thinking has changed. The connection notebook's short prompts cover each of these, and help you turn what you learn into one change in practice.
Much of this evidence comes from laboratory and classroom studies, and there are fewer studies in postgraduate medical education. The evidence page sets out the research in more detail, including where it's thinner.
Read the evidenceUsing AI safely
Safety and transparency
Mosaic uses AI to support your learning. Clinical judgement stays with you, and we're upfront about what the AI can and can't do.
✓ Clear disclaimers throughout
Every review reminds you to check the AI's feedback against current guidelines. Mosaic is a learning tool, not a clinical reference. Checking the AI against the guidance is good learning in itself.
✓ UK guidelines referenced
Feedback cites NICE, the BNF, RCGP curriculum guides and other UK sources by name and number rather than generating links. This reduces the risk of an inaccurate reference but doesn't remove it, so check anything you plan to rely on.
✓ Honest about uncertainty
The AI is prompted to flag uncertainty rather than guess, and some questions have answers that are open to debate. It will still sometimes be wrong, which is why every review carries a reminder to check current guidance.
✓ Your data is held in the UK
Your account, content and activity are stored in London (AWS eu-west-2). The one exception is AI review: the question you ask to have reviewed is sent to Anthropic's Claude API, which may process it outside the UK and does not use it for training. Nothing is sold or shared for marketing. Questions you write are private unless you choose to share them.
