Terms of service

GrammarPlus provides free, browser-based writing tools. No account is required, nothing is sold, and the service is provided as-is. We may change, limit or discontinue any tool at any time.

You keep all rights to the text you submit and to the output you get back. We claim no ownership of either, and we do not use your submissions to train anything of ours. What the AI provider does with a request in transit is covered on the privacy page.

You are responsible for having the right to submit what you submit — in particular for confidential material belonging to an employer or client.

You agree not to use these tools to:

• generate or refine content that is unlawful in your jurisdiction;
• impersonate a person or organisation, or produce material intended to deceive about its origin;
• circumvent the rate limits, whether by script, proxy rotation or clearing browser storage in a loop;
• resell access, or wrap these endpoints in another product or API.

Rate limits apply per browser and per IP address. They exist to keep the tools free and available, and hitting them occasionally is normal use, not a violation.

AI output is probabilistic and can be wrong. Nothing here is professional, legal, medical or academic advice, and you should read what a tool returns before relying on it.

Two cases deserve naming. The AI detector reports a probability, not proof of authorship. No detector can establish that a human wrote a text, false positives are common — they fall hardest on non-native writers — and its output must not be used as evidence in an academic-misconduct process. The citation generators format the details you provide and flag what is missing; they do not verify that a source exists. Check every citation against the source.

Whether these tools may be used on graded work is set by your institution, not by us. Check your course policy first.

The service is provided “as is”, without warranties of any kind, express or implied, including fitness for a particular purpose. We do not warrant that the tools will be available, uninterrupted or error-free.

To the fullest extent the law allows, GrammarPlus is not liable for indirect, incidental, special or consequential loss, for lost profits or revenue, or for loss of or damage to data, arising from your use of these tools. Because the service is free and no fee is paid, total direct liability is limited to zero.

Two things that exclusion does not touch. Nothing here limits liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation. And nothing here removes or reduces a right you have as a consumer under the mandatory law of your own country — where that law and these terms conflict, that law wins.
