README Summary

Local Deep Researcher is a fully local web research assistant that uses any LLM hosted by [Ollama](https://ollama.com/search) or [LMStudio](https://lmstudio.ai/). Give it a topic and it will generate a web search query, gather web search results, summarize the results of web search, reflect on the summary to examine knowledge gaps, generate a new search query to address the gaps, and repeat for a user-defined number of cycles. It will provide the user a final markdown summary with all sources us
