How to Check Grammar and Spelling in Your Writing

A single typo can undercut an otherwise strong piece of writing. A misspelled word in a cover letter, a wrong "your/you're" in an email to a client, a doubled word in a report — small errors carry an outsized cost because readers notice them and judge accordingly. A grammar checker catches these before anyone else does. This guide explains what a checker catches, its limits, and how to write cleaner.

What a grammar checker catches

A checker scans your text for the common, mechanical errors:

Catching these is the highest-value proofreading you can do, because they are the errors readers spot instantly.

How to check grammar with this tool

  1. Open the Basic Grammar Checker tool.
  2. Paste your text.
  3. Review the flagged issues.
  4. Fix and copy the cleaned text.

Everything runs in your browser, so your writing — a private email, an unpublished draft — is never uploaded.

Know the limits

A basic grammar checker is a safety net, not an editor. It reliably catches mechanical errors but cannot judge whether your writing is *good*:

Use it to remove the obvious mistakes, then read the text yourself for sense and flow.
