Before you choose

Requirements & limits

The project README describes a hosted Streamlit app and a local setup. It requires an OpenAI API key for the documented local setup. The repository is licensed under MIT.

  • The documented workflow requires an OpenAI API key.
  • The project uses Streamlit, LangChain, OpenAI's Chat API, and vector-database retrieval; FAISS is among the listed technologies.
  • The README reports that PDF display in the deployed app works only in certain browsers, including Safari and Firefox; local PDF display is described as working fine.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
