Who operates this service
AI by AI ("the Service") is operated by VR Express OOD, a company registered in Bulgaria under company number (ЕИК) 203447777, VAT BG203447777, with registered seat at ул. „Тридесет и четвърта“ 14, с. Гомотарци, Vidin municipality, Bulgaria. Contact: ilian@vrexpress.io
What the Service is
AI by AI is an educational platform. Lessons are paired with a lab that sends your prompt to two large language models and shows their responses side by side. The Service is provided for learning purposes.
Accounts
You need an account to use the lab and the Navigator. You are responsible for keeping your credentials secure and for everything done through your account. You must be at least 16 years old to create one.
AI-generated output
Responses shown in the lab and by the Navigator are generated by third-party language models. They can be inaccurate, incomplete, or confidently wrong. Do not rely on them as professional, legal, medical, or financial advice, and verify anything that matters before acting on it.
Acceptable use
Do not use the Service to generate unlawful content, to attempt to break or overload it, to reverse-engineer it, or to resell access to it. We may suspend an account that does.
Usage limits
Use of the lab and the Navigator is subject to a daily limit. We may change that limit at any time.
Pricing
The Service is currently free to use. No paid plan is available yet, and no payment is taken. Where a price is shown on the Service, it indicates intended future pricing only and creates no obligation on either side.
Intellectual property
Lesson text, course structure and the Service itself belong to VR Express OOD. The prompts you write remain yours.
Availability and liability
The Service is provided "as is", without warranty of any kind. It may be changed, interrupted, or discontinued at any time. To the extent permitted by Bulgarian law, VR Express OOD is not liable for indirect or consequential loss arising from use of the Service.
Governing law
These terms are governed by the laws of the Republic of Bulgaria.
Changes
We may update these terms. The date at the top shows when they last changed.
