QuillBot
An AI writing tool for paraphrasing, grammar checking, summarizing and translating text.
What is QuillBot?
QuillBot is an AI writing assistant best known for its paraphrasing tool. It also offers grammar checking, summarizing, translation, citation help and an AI detector, on the web and as browser and Word extensions.
The paraphraser rewrites sentences in different modes, such as fluent, formal, simple or creative, which helps when you need a clearer or different version of your own text.
Grammar and spelling checks catch errors as you write, and the summarizer condenses long articles into key points.
Students, non-native speakers and marketers use it to polish writing quickly.
For creators, it is useful for tightening captions and adapting tone, though originality should come from your own ideas.
