Build Your Own Private AI Search Engine Using Open-Source Tools

This article details how to build a private, local AI-powered search engine similar to Perplexity. It explains that Perplexity operates on a retrieval-augmented generation (RAG) pipeline, which involves turning user questions into search queries, fetching and cleaning relevant web content, and then feeding this information to a language model with strict instructions to answer based solely on the provided sources. The author outlines a stack for a local-first implementation using Ollama for running language models like Llama 2 or Mistral, and SearXNG for the search layer, emphasizing the privacy benefits of keeping all operations on personal hardware.
