What is Spinbot?
Spinbot is a free web-based paraphrasing tool that rewrites text you paste in, producing a reworded version of articles, essays or other content. The free version takes up to 10,000 characters (about 1,000 words) per use and needs no sign-up or registration.
Alongside the paraphraser, Spinbot publishes a set of related writing tools on its site: an AI summary generator and summarizer, a grammar checker, spell checker, punctuation checker, online proofreader and an essay checker.
The free tools are supported by ads. Spinbot's about page says an ad-free version can be bought, but no price is listed on the pages we could access. It suits students, bloggers and content writers who want quick rewording or proofreading in the browser without creating an account.
