About

QuillBot is an online AI writing tool designed to help people rewrite, refine, and polish text faster than manual editing. At its core is a paraphraser that rewords sentences and paragraphs while preserving meaning, and the platform also includes utilities for grammar checking, summarizing, and related writing tasks.

Users paste text into the web-based editor or use the QuillBot browser extension, choose from paraphrasing modes, and receive rewritten output they can compare against the original. The service is built by a team focused on natural language processing and is widely used in academic and professional writing workflows. Because the vendor's site could not be fully reviewed during preparation of this listing, feature details below are limited to widely known, uncontroversial public information about the product.
