Why use a grammar checker?
Good grammar builds credibility. Whether you are writing an email, essay, blog post, or social media update, grammatical errors can undermine your message and make you appear less professional. Our free grammar checker scans your text for common issues like double spaces, missing capitalisation after full stops, commonly confused words, and repeated words — all without sending your text to any server.
What does this tool detect?
This checker looks for commonly confused words such as their/there/they're, your/you're, and its/it's. It also flags double spaces, missing capitalisation at the start of sentences, repeated consecutive words, and missing full stops at the end of your text. While it cannot replace a professional editor, it catches the most frequent mistakes writers make.
