A small local RAG Q&A tool for OSP resources

[Slow-Walker66]

Hi everyone,

I recently made a small local retrieval-augmented Q&A tool for the Open Systems Pharmacology Suite, especially PK-Sim and MoBi.

The motivation was simple: many useful answers already exist in the official documentation and in previous forum discussions, but it is sometimes time-consuming to find the right thread or section when working on a specific modeling question. I built this tool to make better use of these existing resources and to retrieve relevant information more quickly.

The tool indexes local OSP Suite PDF documentation together with discussions from the Open-Systems-Pharmacology Forum. It uses a local Chroma vector database for retrieval and then generates answers based only on the retrieved context. Answers include references back to the source PDF pages or GitHub discussion posts, so the original information can still be checked manually.

A few features:

• Local knowledge base and vector index
• Search across OSP Suite documentation and GitHub Forum discussions
• Support for English, Chinese, and mixed-language questions
• Source citations for manual verification
• Optional refresh to include newly updated forum discussions

This is not intended to replace the official documentation, forum search, or expert review. It is just a small helper tool that may make it easier to find relevant existing information when using PK-Sim / MoBi.

I am sharing it here in case it is useful to others in the community. Feedback, suggestions, or improvements are very welcome.
