QuillBot

QuillBot is a focused tool in the writing category built around paraphrasing and everyday writing help. Rather than generating content from scratch, it takes text you already have and makes it clearer, more concise or better phrased.

What it does

QuillBot’s core is its paraphraser, which rewrites sentences and paragraphs in several modes so you can adjust tone, formality and length. Around it sit a grammar and spelling checker, a summariser that condenses long passages into key points, a citation generator, and tools for improving fluency and tone. Browser extensions and add-ins bring these features into your browser, Google Docs and Word, so you can rewrite and check text where you already write.

Who it’s for

QuillBot is popular with students, non-native English writers, and professionals who want to polish drafts quickly. The free paraphraser and grammar checker handle a lot on their own, while Premium lifts word-count limits and unlocks extra modes and features at a modest price. As with any AI rewriter, a quick human read-through keeps meaning intact and citations honest.
