PalimpChat: Declarative and Interactive AI analytics
This work addresses the accessibility gap in AI analytics for non-experts, though it is incremental as it builds on existing declarative frameworks like Palimpzest.
The paper tackles the problem of making declarative AI frameworks accessible only to expert programmers by introducing PalimpChat, a chat-based interface that allows non-experts to create and run sophisticated AI pipelines through natural language, demonstrated in real-world scenarios like scientific discovery and legal discovery.
Thanks to the advances in generative architectures and large language models, data scientists can now code pipelines of machine-learning operations to process large collections of unstructured data. Recent progress has seen the rise of declarative AI frameworks (e.g., Palimpzest, Lotus, and DocETL) to build optimized and increasingly complex pipelines, but these systems often remain accessible only to expert programmers. In this demonstration, we present PalimpChat, a chat-based interface to Palimpzest that bridges this gap by letting users create and run sophisticated AI pipelines through natural language alone. By integrating Archytas, a ReAct-based reasoning agent, and Palimpzest's suite of relational and LLM-based operators, PalimpChat provides a practical illustration of how a chat interface can make declarative AI frameworks truly accessible to non-experts. Our demo system is publicly available online. At SIGMOD'25, participants can explore three real-world scenarios--scientific discovery, legal discovery, and real estate search--or apply PalimpChat to their own datasets. In this paper, we focus on how PalimpChat, supported by the Palimpzest optimizer, simplifies complex AI workflows such as extracting and analyzing biomedical data.
