AI Agent FletUI provides a modular UI framework for creating intelligent chat applications backed by large language models. It bundles chat widgets, tool integration panels, memory stores and event handlers that connect seamlessly with any LLM provider. Users can define custom tools, manage session context persistently and render rich message formats out of the box. The library abstracts the complexity of UI layout in Flet and streamlines tool invocation, enabling rapid prototyping and deployment of LLM-driven assistants.
