Free IELTS writing tool
IELTS Vocabulary Improver
Lexical Resource counts for a quarter of your IELTS Writing band, and the fastest way to lose marks is repeated, approximate word choice or a memorised "big word" used wrongly. Paste your basic words and this tool suggests higher-band, natural alternatives with the right collocation, plus the band range each upgrade targets.
How to use it well
- Choose precision over rarity. Keep an upgrade only if it reads naturally for your sentence. A misused advanced word costs you marks, so see how Lexical Resource is scored before swapping words in.
- Match the task. Use trend and data language for Task 1 and argument language for Task 2, which is weighted twice as heavily in your Writing band.
- Get a full check. This automated tool gives quick ideas, not a band. For a marked answer across all four criteria, use our IELTS writing correction service with a qualified teacher.
IELTS Vocabulary Improver — common questions
What does the IELTS Vocabulary Improver do?+
Paste basic words or phrases and it suggests higher-band, natural alternatives with the right collocation. It targets the Lexical Resource criterion, which is worth a quarter of your Writing band on both Task 1 and Task 2.
Will using rarer words raise my band?+
Not on their own. Examiners reward precise, natural word choice and accurate collocation, not showy vocabulary. A misused rare word lowers your score, so the tool flags when a common word used correctly is the safer, higher-band choice.
Does it help with both Academic and General Training?+
Yes. The same Lexical Resource criterion applies to Academic Task 1 reports, General Training letters and Task 2 essays. Match the suggestions to your task: data and trend language for Task 1, argument and topic language for Task 2.
Can this guarantee a band 7 or higher?+
No. It is an automated self-check for instant ideas and cannot promise any band. For a real assessment, a qualified teacher marks your full answer against all four criteria. We are not affiliated with IDP, the British Council or Cambridge.
