What Is QuillBot?

QuillBot is an AI writing platform. Its Writing Studio helps users paraphrase text, check grammar, review tone and improve how sentences flow. Users can type, paste or upload text, then choose a mode and apply the changes. QuillBot also offers a summarizer, an AI Detector, a humanizer, AI Chat and a Chrome extension that works across apps and websites.

Who Should Use QuillBot?

QuillBot is useful for writers and professionals who need to reword text, fix grammar or shorten long passages. Teams can use the Team Plan for shared billing and a user dashboard. Readers who need long inputs should check the word limits, because the Free plan caps several tools.

How Does QuillBot Work?

1. Type, paste or upload your text.

2. Pick a tool, such as the Paraphraser, grammar checker, Summarizer or AI Detector.

3. For paraphrasing, choose a mode and move the synonym slider left for fewer changes or right for more changes.

4. Click Paraphrase, then review the result. You can click a word to see other word choices.

5. Copy the new text or use the QuillBot Chrome extension in other apps and websites.
