A grammar checker is a tool designed to automatically check your text for spelling errors, grammatical issues, punctuation mistakes, and problems with sentence structure. You can check out our analysis of the best free grammar checkers to learn more.
A paraphrasing tool edits your text more actively, changing things whether they were grammatically incorrect or not. It can paraphrase your sentences to make them more concise and readable or for other purposes. You can check out our analysis of the best free paraphrasing tools to learn more.
Some tools available online combine both functions. Others, such as QuillBot, have separate grammar checker and paraphrasing tools. Be aware of what exactly the tool you’re using does to avoid introducing unwanted changes.
