Use of English AI

Use of English AI is the closest thing to a tireless private tutor I've used for Cambridge prep. It generates fresh Use of English and Reading exercises on demand for B1 through C2, then marks your Writing against Cambridge criteria in seconds. No two sessions feel the same, which is exactly why I kept coming back.

A generator that never runs out of Cambridge practice

Most study apps hand you a fixed pile of questions, and once you've worked through them, that's it. Use of English AI, from Shining Apps LLC, takes a different route. It uses Natural Language Processing trained on a database of over 15,000 official Cambridge materials to produce a virtually endless stream of practice. In plain terms: you rarely see the same exercise twice, and that variety is what kept my grammar and vocabulary sharp instead of memorising answers.

It supports the full ladder of Cambridge levels: B1 Preliminary (PET), B2 First (FCE), C1 Advanced (CAE) and C2 Proficiency (CPE). The system generates and refines every major task type I care about, so the practice matches whatever paper you're sitting.

The exam tasks it actually builds

• Use of English: open cloze, word formation and key word transformation, tuned to your chosen level.
• Reading: tougher formats like missing paragraphs and long texts, not just quick multiple choice.
• Writing: articles, reports, reviews, essays and proposals you can draft right inside the app.
• Context awareness: because the AI understands context, it tweaks each question for a genuinely fresh challenge rather than reshuffling the same wording.

Writing feedback that mirrors the marking criteria

The standout feature for me is the Writing evaluation. You write an essay, report or proposal, and the in-house AI models, aligned with official Cambridge marking criteria, return an immediate score plus concrete suggestions. Writing is the part most students dread, and being able to iterate on structure and style in real time, again and again, felt like having a fast digital tutor sitting next to me. It's the kind of focused, repeatable practice that's genuinely hard to build on your own.

A library that keeps improving itself

There's a smart quality-control loop running underneath. Exercises are rated by the community; the strong ones are saved for future use and the weak ones get removed automatically. It's a survival-of-the-fittest system that keeps the material accurate over time. When the AI occasionally invents an entirely new exercise on its own, it's clearly marked, so you always know what you're looking at. I appreciated that transparency.

Fair use, and how to start

To keep performance stable for everyone, the app lets you generate three AI-powered exercises every five minutes, which honestly suits deep, focused study better than firing off dozens at once. Behind that pace sits a library trained on more than 15,000 official Cambridge materials, the community-rated quality loop that keeps the strongest tasks, and a support team that answers quickly when you need a hand. It works across desktop, tablet and mobile, and you'll find it at useofenglish.ai, on iOS and on Android.

My take after real use

If your weak spot is the sheer repetition needed to master Use of English, Reading and Writing, this is a tool worth having. It was built by data engineers and refined by English teachers, and that blend shows: the exercises feel authentic, the feedback is specific, and the endless variety means you can drill collocations, phrasal verbs and transformations for weeks without hitting a wall. For B1, B2, C1 or C2 candidates who want variety, accuracy and instant results, Use of English AI comes as close to a personal tutor as an app reasonably can.
