Examiner-grade IELTS feedback,
available to everyone
mockDe was built on a simple observation: the gap between a Band 6.5 and a Band 7.5 is not talent - it is the quality of feedback a student receives. Most students never get examiner-level insight into their writing and speaking. We are changing that.

What we stand for
Examiner-grade accuracy
Our AI is calibrated against the same four-criterion IELTS band descriptors real examiners use. Every model update is benchmarked against human scorer agreement before release.
Multi-agent evaluation
Four specialist AI agents evaluate your writing and speaking simultaneously - one per criterion - so no single aspect is ever rushed or given less attention than another.
Evidence-based content
Every article is written by IELTS specialists and reviewed against current Cambridge band descriptors. No guesswork, no recycled generic advice.
Speed without compromise
Criterion-level feedback in under 30 seconds. No waiting days for a tutor, no vague comments. Just precise, actionable guidance you can apply today.
How our multi-agent evaluation works
When you submit a Writing or Speaking response, five AI agents work simultaneously - each one focused only on its own criterion. This mirrors how a real IELTS double-marking panel operates, except the result arrives in under 30 seconds.
Agent 1 - Task Achievement
Reads only for whether you fully answered the question. Scores and comments independently.
Agent 2 - Coherence & Cohesion
Analyses paragraph structure, logical flow, and use of linking language.
Agent 3 - Lexical Resource
Measures vocabulary range, precision, and avoidance of repetition.
Agent 4 - Grammatical Range & Accuracy
Checks sentence variety, tense control, and grammatical correctness.
Coordinator Agent - Band Report
Combines all four criterion scores into a single consistent band score and produces your personalised Roadmap to +1 Band.
The same five-agent pipeline evaluates Speaking tests, with an additional transcription agent that accurately preserves hesitations and fillers - which matter for Fluency & Coherence scoring.
