## Overview

GrammarChecker is a browser-based proofreading workspace aimed at people who want a quick second pass over a draft without installing software or creating an account. You paste or type text into a single editor, press the check button, and the tool highlights issues across four core areas: grammar, spelling, punctuation and style. Alongside the fixes it shows counters for sentences, paragraphs, lines, words, characters and syllables, plus estimated reading and speaking time and a readability score.

The tool deliberately keeps the writer in control. Instead of rewriting whole passages automatically, it surfaces suggestions and leaves the final decision to you, which matters for essays, professional emails and anything where tone and meaning need to stay intact. Practical extras are bundled into the same page: a free AI-detector scan that estimates whether your text looks machine-generated, a thesaurus for word swaps, a title capitalizer, and quick converters for sentence case, lowercase, uppercase and title case, along with reference presets for APA, AP, AMA, CMOS, Harvard and MLA styles.

On-page copy also includes social-post length guidance for X/Twitter, Facebook, Instagram and YouTube, so short-form writers can sanity-check a caption before publishing. Because the tool is free and needs no account, it is a lightweight option for students, support and marketing teams, and anyone who wants a fast check on a shared or borrowed device. There is no pricing page; the checker is offered at no cost.

## Primary Use Cases

- **Polish essay paragraphs before submission (Students):** Check one paragraph or section at a time to catch grammar, punctuation and clarity slips without letting an automatic rewrite alter the argument.
