Terms & Conditions

These Terms and Conditions ("Terms") govern your access to and use of the Brian AI web application available at usebrian.app, operated by Brian AI ("we", "us", or "our"). By creating an account or using the service you agree to these Terms.

1. Acceptance of Terms

By accessing or using Brian AI you confirm that you are at least 16 years old, have read and understood these Terms, and agree to be bound by them. If you are using Brian AI on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms.

2. Description of Service

Brian AI is an AI-powered productivity assistant that lets you chat with an AI, maintain notes, organise projects, and build a persistent memory layer across your work. The service is provided "as is" and may evolve over time. We reserve the right to modify, suspend, or discontinue features with or without notice.

3. Account Registration

You must provide a valid email address and keep your credentials secure. You are responsible for all activity that occurs under your account. Notify us immediately at support@usebrian.app if you suspect unauthorised access.

4. Acceptable Use

You agree to use Brian AI only for lawful purposes and in a way that does not infringe the rights of others. You must not:

• Use the service to generate or distribute illegal, harmful, defamatory, or harassing content.
• Attempt to reverse-engineer, decompile, or extract the underlying AI models or source code.
• Circumvent rate limits, access controls, or any other technical restrictions.
• Use automated scripts to access the service in a way that exceeds normal personal use.
• Use the service to build a competing product without our prior written consent.
• Upload or transmit viruses, malware, or any other malicious code.

We reserve the right to suspend or terminate accounts that violate these rules.

5. AI-Generated Content

Brian AI uses large language models to generate responses. AI-generated content may be inaccurate, incomplete, or outdated. You are solely responsible for verifying any information before relying on it for decisions — especially in medical, legal, financial, or other professional contexts. We make no warranty that AI responses are correct, complete, or fit for any particular purpose.

6. Your Content

You retain ownership of all content you create in Brian AI (messages, notes, projects). By using the service you grant us a limited, non-exclusive licence to store and process that content solely to operate and improve the service for you. We do not use your content to train shared AI models or sell it to third parties.

7. Intellectual Property

The Brian AI name, logo, interface design, and underlying technology are owned by us and protected by applicable intellectual property laws. Nothing in these Terms grants you a right to use our trademarks or branding without prior written permission.

8. Plans, Billing, and Cancellation

Brian AI offers a free tier and paid subscription plans. Paid plans are billed in advance on a monthly or annual cycle. All fees are non-refundable except where required by law or at our sole discretion.

You may cancel your subscription at any time via your account settings. Cancellation takes effect at the end of the current billing period; you will retain access until then.

We reserve the right to change pricing with 30 days' notice. Continued use after a price change constitutes acceptance.

9. Privacy

Our collection and use of personal data is governed by our Privacy Policy, which is incorporated into these Terms by reference.

10. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.

11. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BRIAN AI SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF OR INABILITY TO USE THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ANY CLAIM ARISING FROM OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM OR (B) €50.

12. Indemnification

You agree to indemnify and hold harmless Brian AI and its officers, employees, and contractors from any claims, damages, and expenses (including legal fees) arising from your breach of these Terms or your misuse of the service.

13. Termination

We may suspend or terminate your account at any time for violation of these Terms or for any other legitimate business reason, with or without notice. You may delete your account at any time via Settings → Account → Danger Zone. Upon termination, your right to use the service ceases immediately.

14. Governing Law and Disputes

These Terms are governed by the laws of the European Union and the jurisdiction in which Brian AI is registered, without regard to conflict of law principles. Any disputes shall be resolved by the competent courts of that jurisdiction, unless mandatory consumer protection law in your country provides otherwise.

15. Changes to These Terms

We may update these Terms at any time. We will notify you by email or in-app notice at least 14 days before material changes take effect. If you do not accept the updated Terms, you must stop using the service before the effective date.
