Terms of Service

Last updated: October 28, 2026

AI Checker Plus ("we", "us") is operated by Aleph Labs. By using aicheckerplus.com you agree to these terms.

The service

AI Checker Plus estimates how likely a text was written by artificial intelligence and, on paid plans, checks it for passages that match published sources. Free use is limited to the first 300 words of a text and a few checks a day. Paid plans include the words per month and per check shown on the pricing page.

Results are estimates

AI detection is probabilistic and can be wrong, in both directions. A result is not proof that anyone did or did not use AI or copy text. Do not make decisions about a person (grades, discipline, employment) based only on a result: look at the highlights, drafts and other evidence, and give the writer a chance to explain. The service is provided "as is", without warranties of accuracy or fitness for a purpose.

Your account and payments

Paid plans are bought through Stripe. Monthly and yearly plans renew automatically until you cancel; you can cancel anytime from your account page and keep access until the end of the paid period. The semester pass is a single payment for 4 months and does not renew. Prices may change for future periods with notice. See the refund policy.

Acceptable use

Only submit text you have the right to submit. Do not use the service to break the law, to harass anyone, to probe or overload our systems, or to resell results in bulk without our written permission. We may suspend accounts that abuse the service, including chargeback fraud.

Liability

To the extent the law allows, our total liability for any claim is limited to the amount you paid us in the 3 months before the claim, and we are not liable for indirect or consequential losses.

Changes and contact

We may update these terms; the date above shows the latest version. Questions: support@aicheckerplus.com.
