Writesonic vs BAND9AI IELTS Writing
Content AI · IELTS rubrics · May 2026
Direct answer
Writesonic generates and rewrites marketing-style content; BAND9AI scores your IELTS Writing against official-style Task Response, Coherence, Lexical Resource, and Grammar. Using Writesonic to "improve" essays often produces fluent but generic text that AI checkers love and examiners cap at Band 6. BAND9AI diagnoses leaks on your first draft under exam prompts—not AI replacement paragraphs. Never submit Writesonic output as practice for band prediction.
