I mention that I was doing notes reached for a vector database. I had ChromaDB set up before. But after a while I ripped it out and replaced it with grep.</p> <h3 id="why-i-dropped-rag" class="scroll-mt-8 group"> Why I dropped RAG <a href="#why-i-dropped-rag" class="no-underline hidden opacity-50 hover:opacity-100 !text-inherit group-hover:inline-block" aria-hidden="true" title="Link to this heading" tabindex="-1"> <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round" stroke-width="2" class="lucide lucide-link w-4 h-4 block" viewBox="0 0 24 24" > <path d="M10 13a5 5 0 0 0 7.54.54l3-3a5 5 0 0 0-7.07-7.07l-1.72 1.71" /> <path d="M14 11a5 5 0 0 0-7.54-.54l-3 3a5 5 0 0 0 7.07 7.07l1.71-1.71" /> </svg> </a> </h3> <p>Running a vector database, keeping an embedding model warm, indexing every note on write — that&rsquo;s a lot to ask from a $5 VPS. The thing would just fall over. I want this tool to be lightweight enough that it runs comfortably on the smallest server as possible so RAG was not that. I also just wanted <strong>simplicity</strong>.</p>
