Quillbot

Quillbot is an AI-powered writing assistant built to help you revise, refine, and produce clearer text in less time. It’s commonly used by students, professionals, and creators who want stronger wording without losing their original meaning or voice. At its core, QuillBot lets you paste or write text directly in its editor and generate improved rewrites with the Paraphraser, making it easier to adjust tone, enhance fluency, or remove repetition. Beyond rewriting, QuillBot offers tools that support the full writing workflow: a Grammar Checker for catching mistakes and improving readability, a Summarizer for condensing long passages into key points, and a Citation Generator to quickly format references for academic and research writing. For originality and compliance needs, it also includes a Plagiarism Checker to help identify overlapping text and an AI Detector designed to assess whether content may appear AI-generated. QuillBot also provides an AI Humanizer to make AI-drafted text sound more natural and consistent with human writing.

QuillBot can be used through its web interface: add your text, select the tool you need (such as Paraphraser, Grammar Checker, or Summarizer), and apply the changes. It’s designed to speed up editing while keeping control in the user’s hands—helping improve clarity, correctness, and structure across emails, essays, reports, and social content.
