How it works in practice
Grammar is contextual. A lightweight browser checker can catch deterministic patterns but cannot reliably understand every tense choice, ambiguous sentence, idiom or specialist writing convention.
Catch common typos and grammar slips.
Flag a limited set of common writing slips locally, such as repeated words, spacing patterns and simple usage issues, without pretending to replace a full language model or professional editor.

Use a professional editor or advanced language tool for publication, legal text, academic writing or nuanced style work.
