Hayato-ultra/instagpt-graphrag ? reverse-engineered prompt

Build me a simple Python app called InstaGPT GraphRAG. I want to be able to bring in Instagram related content, organize it in a graph style knowledge layer, and then chat with it so I can ask questions and get grounded answers instead of random guessing.

Please make it feel like a small usable product, not just a script. A lightweight backend with an API is fine, plus a basic web page in the static folder where I can submit content, see what got indexed, and ask questions. Use environment variables for any keys or settings, and make it easy to run from the main entry files that are already here. If there is a sensible way to support richer content beyond plain text, include that only if it fits naturally.

Keep the setup straightforward and leave clear notes in the code so I can understand what is happening. If you need to, look up current docs online and make reasonable choices.
