Grammar Checker
Free online tool that flags and fixes grammar, spelling, style errors.
About Grammar Checker
StudyCrumb's Grammar Checker is a free browser-based tool that scans pasted text for spelling, grammar, punctuation, and style problems. Rather than flagging words in isolation, it is described as evaluating meaning across a sentence or passage, then presenting suggested fixes that users can accept or ignore. Results are color-coded by type: red for spelling errors, yellow for grammar issues, and blue for style and writing suggestions. The tool accepts up to 400,000 characters, roughly 7,500 words, in a single check, and it requires no account or sign-up to use. It is offered entirely free by StudyCrumb, a company that otherwise sells academic writing, editing, and proofreading services, with the free checker functioning as a lead-generating tool alongside its paid offerings. A limitation is that StudyCrumb does not disclose which underlying language model or grammar-checking technology powers the tool beyond describing it as using "improved AI algorithms," and no independent accuracy comparison against dedicated grammar tools is published on the site.
