Copula AI is an innovative web application that leverages advanced AI technology to create custom Q&A websites. Utilizing articulated language model (LLM) technology, it allows users to develop a ChatGPT-style interface where the AI answers queries based on provided documents. Users can upload their reference texts, typically stored in Google Drive, which the AI utilizes to generate responses. The platform emphasizes accountability by citing the sources of information used in its answers, enhancing the reliability of the responses.

The service includes a free version that allows users to perform Q&A using a single document or webpage. This version also provides a shareable link and a bookmarklet for easy submission of web pages to the AI for future queries. Copula AI is versatile, making it suitable for various sectors, including law, healthcare, and education, enabling users to create tailored websites that cater to specific informational needs.
