1. The service

Ptex provides free online tools for working with text, including an AI humanizer, AI detector, paraphraser, grammar checker, summarizer, and word counter. The tools are offered for general use, with no account required.

2. Acceptable use

You agree to use Ptex only for lawful purposes. You must not:

• Use the tools to misrepresent authorship, to submit work that must be your own original writing, or to deceive an employer, teacher, or publisher.
• Enter content that is illegal, or that you do not have the right to use.
• Attempt to overload, disrupt, scrape, or abuse the service, or get around its usage limits.

3. AI results

Results are generated by an AI model and are provided as is. They can contain mistakes, so you should review every result before you use or publish it. You are responsible for how you use the output.

4. No guarantees

Ptex does not guarantee that a result will pass any AI detector as human written, and does not guarantee that the tools will be available without interruption or free of errors. The service is provided without warranties of any kind.

To the extent permitted by law, the site owner is not liable for any loss or damage arising from your use of, or inability to use, Ptex or its results.

Your use of Ptex is also covered by our Privacy Policy, which explains what data is collected and how it is handled.

7. Changes to these terms

These terms may be updated from time to time. When they change, the new version is posted on this page with a revised last updated date. Continuing to use the site means you accept the current terms.
