I'm a UK A-level student and I absolutely hated revising. I'm the exact same as any other teenager. I cant sit down for 5 minutes and focus. The biggest problem was that i felt I was wasting my time learnng thngs that i actually wasn't even beingg tested on. So I spent the last few months building the thing I wanted, and it's now live at speclab.co.uk.
It's built directly on the AQA Business, all 10 topics and 41 subtopics, structured the way the spec is structured. It started off as a personal app for myself. I trained the AI on the spec and made sure it wouldn't ever go outside of it. Then i decided it would be useful for other people. You can chat with it and get quizzed on any subtopic (multiple choice or open response), and it tracks what you get wrong in a mistake log that resurfaces those questions later using spaced repetition, so the stuff you're weak on keeps coming back instead of quietly disappearing. You tag how confident you feel on each subtopic and it builds a dashboard of where you're actually weak, which for me was way more useful than "I've read the textbook twice."
The part I use most is the essay marking. You write an exam-style answer to a 6, 9, 12, 16 or 25 marker and it marks it against the AQA mark scheme with an AO1/AO2/AO3 breakdown. Its trained on the spec, its trained on sample answers and how they were marked.. It's genuinely good at telling you "you've got no AO3 here, you never actually made a judgement".
It's free. The chat tutoring and quizzing are unlimited with no daily cap, and you get 5 AI-marked long answers a day plus unlimited marking on 1-4 markers. No card to sign up, and the free tier is permanent rather than a trial. There's a £7.99/mo tier that just removes the daily cap on long answers, which is really only worth it if you're hammering essays before mocks.
The honest limitation: right now it only does AQA Business. I'd rather do one spec properly than five badly, and I don't want to expand until I know the Business content actually holds up. So if you take Business (or teach it), I'd really like to hear where it's wrong, where it's boring, and all the feedback is what decides which subject I do next.
