Methodology
How IELTS Writing AI turns an essay into score-focused feedback
This page explains how the product reads a draft, maps findings to IELTS criteria, and decides what should be fixed first. It exists so users can understand what the checker measures before trusting the score signal.
4 criteria
Every report maps to TR, CC, LR, and GRA
1 next fix
The output prioritizes the first score-moving revision
+/-0.5
Band direction is designed to stay useful for revision decisions
How the scoring signal is built
The goal is not to imitate generic correction tools. The workflow is designed to answer a harder question: which IELTS criterion is actually limiting this draft right now?
1. Prompt and essay intake
The system checks the essay type, task intent, and response length before producing any score explanation. This prevents grammar-only feedback from being mistaken for IELTS scoring.
2. Four-criteria diagnosis
Feedback is organized around Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy so users can see where band loss is concentrated.
3. Sentence and pattern review
The tool looks for repeated weaknesses such as missing overview statements, weak idea support, repetitive vocabulary, and unstable grammar control in comparative or complex sentences.
4. Actionable revision output
The goal is not only to describe what is wrong, but to show what should be fixed next. Higher-value plans expose more criterion evidence, rewrites, and repeat-use workflows.
Free diagnosis
Shows the likely band direction, the weakest criterion, and the main reason this draft is being held back.
Deeper feedback
Adds more criterion evidence, clearer rewrite direction, and a more repeatable study workflow across multiple essays.
How to read a band estimate correctly
- Use the estimate to decide what to revise next, not to assume an official exam outcome.
- Look for repeated weak criteria across multiple essays before changing your study plan.
- Treat stronger examples, clearer structure, and better idea support as more important than surface polishing alone.
Methodology limits
- The product is a diagnostic and revision tool, not a replacement for the official IELTS exam.
- Band estimates are intended to reveal likely bottlenecks, not to guarantee an official score.
- Users should compare multiple essays over time instead of treating one draft as a final prediction.
