OpenWebUI Tools provides a collection of plugins for OpenWebUI to enhance large language models with external tool access. It includes a web browsing and search module for live data retrieval, a Python REPL and terminal executor for on-the-fly code running, file system readers/writers for document access, and utilities for parsing PDFs or formatting JSON. These tools operate within the OpenWebUI front-end, letting users interactively call functions and combine AI reasoning with real-world actions for richer conversational and task-oriented experiences.
