Cambridge Exam AI

What is Cambridge Exam AI?

Cambridge Exam AI is an online platform dedicated to helping students prepare for Cambridge English exams at B1, B2, C1, and C2 levels. You can create custom exercises by describing what you need to an AI — simply write a prompt and get your personalized exercise instantly. Our AI models are trained on thousands of real Cambridge English exam papers, ensuring exercises that feel authentic and exam-accurate.

Which Cambridge exams can I prepare for?

We support all four main Cambridge English Qualification levels: B1 Preliminary (PET), B2 First (FCE), C1 Advanced (CAE), and C2 Proficiency (CPE). Each level includes comprehensive practice for Reading, Use of English, Grammar, and Writing sections. All exercises are designed to match the real exam format and difficulty.

How does the AI exercise generator work?

Creating an exercise is simple! First, choose your CEFR level (B1, B2, C1, or C2) and select your course area (Reading, Use of English, Grammar, or Writing). Then pick the specific exercise type you want to practice — like open cloze, word formation, multiple choice, essay writing, etc. You can also choose the tone in which the AI should write the exercise. Finally, write a prompt describing your specific needs. The AI will generate your custom exercise in seconds!

What if I don't have any ideas for a prompt?

No inspiration needed to get started! Our teaching staff have put together a set of ready-made prompt suggestions that appear as clickable chips directly below the prompt field on the Generator page. Just tap any of them to instantly fill in the prompt — then hit Generate. We recommend using these examples for your first few exercises so you can get a feel for how the generator works.

How does the credit system work?

PRO subscribers receive AI Credits every billing cycle — 150 credits per month on monthly and yearly plans, or 30 credits per week on the weekly plan. Reading, Use of English, or Grammar exercises cost 1 credit each. Writing exercise generation costs 0.5 credits, and submitting a writing for AI evaluation costs another 0.5 credits. You can track all your credit transactions in the AI Credits Ledger, which works like a bank account statement.

Does solving exercises cost credits?

No — solving exercises is completely free for any active subscriber, regardless of plan. Credits are only consumed when you create a new exercise (1 credit), create a writing exercise (0.5 credits), or submit a writing for AI evaluation (0.5 credits). Think of credits as your creation budget, not your usage budget. Once an exercise exists, you can solve it as many times as you like, for free, whether you created it or not.

What's included in the free plan?

The free plan is designed to let you try Cambridge Exam AI before subscribing: 2 free credits to create up to 2 custom exercises, 3 free solvings for Grammar, Reading, and Use of English exercises, 10 Cambridge AI Reels per day — swipeable practice with no credits required, 1 Grammar Battle per day — compete with other learners for free, and 1 solve per day once your 3 free solvings are used.

What happens when I cancel my subscription?

When you cancel, you retain full access until the end of your current billing cycle. Your account then transitions back to the free plan — no immediate lockout. You keep everything you've already paid for until the next scheduled billing date. If you change your mind, you can reactivate your subscription at any time before the cycle ends.
