21 Lessons, Get Started Building with Generative AI

A lightning-fast search engine API bringing AI-powered hybrid search to your sites and applications.

A no-code RAG server that keeps answers in sync with your documents. Works with 8 vector databases. Built on Pathway.

Your AI second brain. Self-hostable. Get answers from the web or your docs. Build custom agents, schedule automations, do deep research. Turn any online or local LLM into your personal, autonomous AI (gpt, claude, gemini, llama, qwen, mistral). Get started - free.

Open-source LLM knowledge platform: turn raw documents into a queryable RAG, an autonomous reasoning agent, and a self-maintaining Wiki.

This repository showcases various advanced techniques for Retrieval-Augmented Generation (RAG) systems. Each technique has a detailed notebook tutorial.
