Questions & Answers

As answered by people managing BandCheck and Optim API.

Which are the primary technologies used for building your product?

BandCheck's answer

BandCheck is a web application powered by large language models fine-tuned for IELTS assessment, combined with speech recognition for Speaking evaluation. The scoring logic is calibrated against official IELTS band descriptors and validated on thousands of real candidate responses.

How would you describe the primary audience of your product?

BandCheck's answer

Self-studying IELTS candidates preparing for Academic or General Training typically students applying to universities abroad and professionals pursuing immigration or work visas. It's especially useful for candidates who can't afford regular tutoring but want objective feedback on where they stand before booking the exam.

What makes your product unique?

BandCheck's answer

BandCheck covers all four IELTS skills – Writing, Speaking, Reading, and Listening in one platform, with instant AI-powered band scores and detailed feedback. Instead of generic grammar checking, it evaluates responses against the official IELTS band descriptors, so you see exactly how an examiner would assess you: Task Achievement, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy for Writing, and equivalent criteria for Speaking. The scoring engine was built on the analysis of thousands of real IELTS responses, which makes the band estimates realistic rather than flattering.

Why should a person choose your product over its competitors?

BandCheck's answer

Most tools in this space focus on Writing only, or give a single score without explaining it. BandCheck gives you a full breakdown across the official criteria plus concrete suggestions on what to fix and it does this for all four skills, not just essays. It's also significantly cheaper than a tutor, you can check dozens of practice responses for less than the cost of one private lesson, and get results in seconds instead of days.

What's the story behind your product?

BandCheck's answer

BandCheck started as a Telegram bot that graded IELTS essays – it checked over 1,200 essays and showed us how much demand there was for fast, honest feedback. Candidates kept asking for the same thing: "What's my real band score, and what exactly should I improve?" We rebuilt it as a full web platform and expanded from Writing to all four skills, so anyone preparing for IELTS can practice the entire exam with instant scoring.
