# TextData > Adaptive AI infrastructure for organizational research. TextData is adaptive research infrastructure for acquiring, preparing, and analyzing textual data in organizational research, built on an LLM-empowered deep-research engine and installed as an open-source system that can be extended and modified by a community of scholars. Research infrastructure in development. The existing implementation is not yet ready for wide external adoption. Proposed work adapts it for TextData and supports the continuing development of its tools, workflows, and agents.
