Terms of Service

Last updated: September 20, 2026

These Terms of Service (“Terms”) govern your use of Cebes (the “Service”), available at cebes.app. Cebes is an independent project operated by Olivier Tardif, based in Calgary, Alberta, Canada. By accessing or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Who may use Cebes

You must be at least 13 years old (or the minimum age of digital consent in your country) to use the Service. If you use it on behalf of an organization, you represent that you are authorized to accept these Terms for it.

2. What Cebes is

Cebes provides AI-generated conversations with characters modeled on historical figures, grounded in public-domain source material. The characters are simulations, not the real people. Please read our AI Disclaimer, which is incorporated into these Terms.

3. AI-generated content

Responses are produced by AI language models and may be inaccurate, incomplete, or fabricated. They are provided for education, reflection, and entertainment only and are not professional advice of any kind. You are responsible for how you use any information from the Service, and you should independently verify anything important.

4. Acceptable use

You agree not to:

  • use the Service for any unlawful purpose or in violation of these Terms;
  • attempt to disrupt, overload, reverse-engineer, or gain unauthorized access to the Service or its systems;
  • circumvent rate limits, bot protection, or other usage or security controls, or access the Service through automated means except as we expressly permit;
  • use the Service to generate content that is illegal, harassing, or harmful, or to infringe the rights of others;
  • resell, redistribute, or commercially exploit the Service without our permission.

5. Accounts

You are responsible for maintaining the confidentiality of your account and for all activity under it. Notify us promptly of any unauthorized use. We may suspend or terminate accounts that violate these Terms.

6. Fees and future paid plans

The Service is currently free to use. Fair-use and usage limits may apply to keep it sustainable, and we may adjust them with notice. We may introduce paid plans in the future; if we do, the price, billing cycle, and renewal and cancellation terms will be presented to you before you subscribe, and if you cancel you will not be charged for any period after the cancellation takes effect.

7. Intellectual property

The historical texts underlying the Service are in the public domain. The Cebes name, design, software, and character implementations are our property or licensed to us. You retain ownership of the messages you submit, and you grant us a limited license to process them solely to operate and improve the Service.

8. Disclaimer of warranties

The Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that its content will be accurate.

9. Limitation of liability

To the maximum extent permitted by law, Cebes and its operators will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of (or inability to use) the Service. To the extent liability cannot be excluded, it is limited to the greater of the amount you paid us in the twelve months before the claim or USD 100.

10. Indemnification

You agree to indemnify and hold harmless Cebes and its operators from any claims, damages, or expenses arising out of your misuse of the Service or your violation of these Terms or of any law or third-party right.

11. Termination

You may stop using the Service at any time. We may suspend or terminate your access if you violate these Terms or if we discontinue the Service. Provisions that by their nature should survive termination will survive.

12. Changes to these Terms

We may update these Terms from time to time. We will revise the “Last updated” date above, and material changes will be made apparent within the Service. Continued use after changes take effect constitutes acceptance.

13. Governing law

These Terms are governed by the laws of the Province of Alberta and the federal laws of Canada applicable there, without regard to conflict-of-laws rules. Any disputes will be subject to the courts located in Alberta, Canada, unless applicable law provides otherwise.
