PromptQL is an AI-designed agent data access tool that retrieves data like a human by first gathering relevant information and then applying appropriate large language models (LLMs) for classification and follow-up processing, significantly improving the efficiency and accuracy of private data retrieval. This technology addresses the limitations of traditional search algorithms in closed domains, particularly when users submit non-standardized queries, allowing PromptQL to better understand and respond. The product background indicates that PromptQL aims to closely collaborate with users to build the first agent for free to assess and enhance the performance of existing AI agents/assistants.
