Real-time English correction with grammar, spelling and tone suggestions

Overseas service Free quota Free tierInternational
Open Grammarly

Grammarly checks English as you write: spelling, grammar, punctuation, sentence clarity and whether a line reads hard or soft, all underlined where you type. It runs in the browser, on the desktop and inside office documents, so form fields and email bodies outside your local files also get suggestions. It offers candidates, not verdicts. With technical terms, internal wording and casual phrasing, wrong corrections are common; read each one before accepting.

What it does

  • Spelling, grammar, punctuation and clarity checks while you write
  • Tone hints for whether a passage reads firm, casual or diplomatic
  • Sentence rewrites with several alternatives for one line
  • Suggestions in the browser, on desktop and inside office documents
  • Repeated-word and consistency checks that help in long documents

Who it is for

  • An English email or client message needs a grammar and tone pass before sending
  • A resume, cover letter or application needs Chinglish smoothed out
  • External docs and changelogs need consistent English
  • A long draft needs checking for run-on sentences, repetition and structure

How to get started

  1. Install the extension or desktop app and test real English in the fields you use
  2. Sort hints into must-fix and optional; do not accept suggestions wholesale
  3. Set your own rules for person, tense and sentence length
