JamAI Base provides a collaborative spreadsheet-like interface for building RAG applications, combining managed memory with vector embedding and reranker orchestration. It offers three core table types: Generative Tables for LLM-driven data generation, Action Tables for real-time LLM backend interactions and workflow orchestration, and Knowledge Tables for structured document storage to enhance LLM context. The platform exposes everything through a REST API while maintaining the simplicity of a spreadsheet workflow.
