vampiresati/lanchain_practice_by_satvir ? reverse-engineered prompt

Build me a Python project that serves as a playground for different AI and LangChain style demos in one place.

I want a simple app where I can try things like chat with memory, basic agent behavior, document and web search style Q and A, structured outputs, database backed questions, image generation, image to recipe, voice or speech features, and a few small local AI examples. It should also include a couple of easy ways to run it, like a web app and a simple script entry point, so I can test each demo without a lot of setup.

Please keep it beginner friendly, with clear examples, a tidy folder structure, and a README that explains how to run everything locally. If anything needs current library guidance, look up the latest docs online before wiring it up.
