Choosing the right tool
A quick guide to which RewriteAI tool fits what you are trying to do.
My text sounds robotic - which tool should I use?
Use the AI Humanizer. Paste the text, pick a writing style, and it rewrites the sentence structure and word choice so the result reads naturally while keeping the original meaning. It is the right tool when the content is already correct but the phrasing sounds machine-written.
I want to check whether text was written by AI - what should I use?
Use the AI Detector. It scans the text for patterns that are common in AI-generated writing and returns a sentence-level report, so you can see which parts look machine-written rather than just getting a single yes-or-no score.
What is the difference between the Rewriter and the Humanizer?
The Humanizer focuses on making existing text sound natural and human. The writing tools - such as the Paragraph Rewriter and SEO Rewriter - are for reworking a draft for a specific goal, like rephrasing a section or aligning a piece with a target keyword. If your text is fine but sounds robotic, start with the Humanizer.
Are these tools free to use?
Yes. Every tool on this page is free to try, and a free account raises your monthly limits. Paid plans add higher limits, history, reports, and API access if you need to process more text.
Which tools work with languages other than English?
The Translator covers 16 languages. The Humanizer also supports a set of languages beyond English. Check the language selector inside each tool to see the current options before you start.
Can I use RewriteAI through an API?
Yes. The Humanizer and Detector are available as API endpoints. See the API documentation for authentication, request format, and example calls.
