Terms of Service

1. Acceptance of terms

By accessing or using Semantix, you agree to be bound by these Terms. If you do not agree, do not use the service.

2. The service

Semantix is a browser-based AI language tutor. It provides a conversational tutor, Anki-style flashcards with spaced repetition, practice modes (cloze, translation, conjugation, scenario, pronunciation, dictation), writing correction, a curriculum path, article import, and achievements across 18 languages. Features may change over time.

3. Your account

You must provide accurate information, keep your credentials secure, and be at least 13 years old (16 in the EU/EEA, or have parental consent). You are responsible for activity under your account. Tell us promptly of any unauthorized use.

4. Acceptable use

You agree not to:

• Use Semantix for any unlawful purpose or to generate unlawful content.
• Attempt to extract, reverse-engineer, or copy the underlying AI model, system prompts, or training data.
• Scrape, bulk-export, or resell the service or its content.
• Circumvent rate limits, usage caps, or security controls, or interfere with the service.
• Harass, abuse, or impersonate others, or upload malicious code.

5. AI-generated content

Tutor replies, corrections, and generated lessons are produced by an AI model and may contain errors. They are provided for educational purposes only and are not professional translation, certification, or advice. Use judgment before relying on them.

6. Intellectual property and your content

Semantix, including its software, design, and curriculum, is owned by Nobler Works LLC and protected by intellectual-property laws. You retain ownership of the content you submit (your messages, writing, and cards). You grant us a non-exclusive license to host, process, and display that content as needed to operate the service for you.

7. Subscriptions and billing

Semantix is currently free to use. We may introduce paid plans. If you purchase a paid plan, you authorize us (and our payment processor) to charge the applicable fees, which may renew automatically until cancelled. We will disclose pricing and renewal terms at the point of purchase, and price changes will not apply to a billing period already paid. Except where required by law, fees are non-refundable.

8. Disclaimer of warranties

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

9. Limitation of liability

To the maximum extent permitted by law, Nobler Works LLC will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits or data. Our total liability for any claim relating to the service will not exceed the greater of the amount you paid us in the 12 months before the claim or USD $100.

10. Indemnification

You agree to indemnify and hold harmless Nobler Works LLC from claims arising out of your misuse of the service or violation of these Terms.

11. Termination

You may stop using Semantix and delete your account at any time. We may suspend or terminate access if you violate these Terms or to protect the service. On termination, your right to use the service ends.

12. Dispute resolution and governing law

We will try to resolve disputes informally first - email legal@semantix.chat. If we cannot, you and Nobler Works LLC agree to resolve disputes through binding individual arbitration rather than in court, and to waive any class action, except where prohibited by law. These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-laws rules.

13. Changes to these terms

We may update these Terms. Material changes will be reflected by the “Last updated” date above; continued use after changes means you accept them.

14. General

If any provision is unenforceable, the rest remains in effect. These Terms, together with the Privacy Policy, are the entire agreement between you and Nobler Works LLC regarding the service.
