Build your own perplexity for your applications using research4j and integrate them for any domain specific usecases
This library helps Java developers integrate automated research capabilities into their applications. It takes a user's query as input and, after dynamically analyzing it, fetches relevant information and citations from various online sources (like Google Search) to generate a detailed answer, which can be presented in formats like Markdown or JSON. This is designed for developers building applications that need to provide intelligent, source-backed responses without manual research.
