Grammar Detector

Who it is for

People who write their answers before they say them, and want to check the habits their first language carries into English. It is most useful for an answer you plan to give often, such as "tell me about yourself", because fixing one pattern there helps every time you say it.

What it checks

• Grammar patterns linked to your first language, such as missing articles, tense changes or word order.
• Each pattern it finds in your answer, with the sentence it came from and a suggested fix.

How to use it

1. Choose your first language.
2. Paste or type an answer you plan to give — at least 10 words.
3. Fix one pattern at a time and say the answer out loud again.

What it cannot do

• It looks for known patterns. It is not a full grammar checker and will not catch every mistake.
• Not every pattern matters: if the meaning is clear, an interviewer may not notice it.
• It runs in your browser — your answer is not uploaded.

Common questions

What is a first-language grammar habit?

A pattern from your first language that appears in your English, often under pressure — for example leaving out "a" and "the" when your first language has no articles.

Is my answer saved?

No. The check runs in your browser and nothing is uploaded.

Which first languages does it cover?

The languages it covers are listed in the menu on the tool. If yours is not there, choose the closest one, or use the free readiness check, which gives feedback on any answer.
