Questions, answered

What is a paraphrasing tool?

A paraphrasing tool rewrites text in different words while keeping the original meaning. It changes vocabulary and sentence structure, so you can say the same thing more clearly, in another tone, or without repeating the wording of the source.

Is this paraphrasing tool free?

Yes. Every visitor gets 10 free rewrites with no sign-up. Each rewrite handles up to 1,500 characters, about 250 words. For unlimited rewriting and longer texts, CopyZai plans include AI writing tools for emails, blogs, ads and more.

Which mode should I use?

Standard rewords naturally at the same length. Fluent fixes awkward phrasing. Formal suits business and academic writing, casual suits chats and social posts, and simple uses short everyday words. Creative gives fresher wording, and shorter cuts the length by about 40 percent.

Does paraphrasing avoid plagiarism?

Rewording someone else’s ideas does not make them yours. If the ideas come from a source, keep the citation, even when the wording is new. Use paraphrasing to explain a source in your own voice, improve your own drafts or adapt text for a different audience.

Will the meaning change?

The tool is instructed to keep every fact, name, number and link, and to change only the wording. Always read the result before you use it, especially for technical, legal or medical text, where one word can change the meaning.

Is my text stored?

Your text is sent to our AI model to be rewritten and is not saved to an account or shown to anyone else. Avoid pasting passwords or sensitive personal information into any online tool.
