Grammar Checker

What is a grammar checker?

A grammar checker scans a piece of writing for spelling mistakes, punctuation slips, and other issues that are easy to miss when reading your own text, and suggests corrections for each one. Instead of proofreading line by line, pasting the text here surfaces the issues automatically, with a suggested fix ready to apply in one click.

It's useful anywhere writing needs to be clean before it goes out — an email, a blog post, a cover letter, a social post, or a report — catching the small mistakes that a quick read-through often misses.

How to use it

How the check works

Each word is checked and, where a possible issue is found, a short list of suggested replacements is generated and ranked by how closely they match the original word. Clicking a suggestion swaps it into the text in place, so the fix can be applied without retyping anything. Spacing issues, like accidental double spaces, are flagged the same way.

Features & benefits

Why this runs entirely in your browser

Text pasted here can include drafts, private messages, or unpublished writing, so nothing is uploaded. Checking runs locally in the tab, which means it keeps working offline once the page has loaded and nothing typed or pasted into it persists after the tab is closed.

Getting the most out of it

Suggestions are a starting point, not the final word — always read a suggested replacement in context before applying it, since the best fix depends on what the sentence is actually trying to say. Names, brand terms, and technical jargon may get flagged even when they're spelled correctly; skip those suggestions when that happens.
