Reviewed resources in RAG. 540 resources listed.
GROBID
grobid.readthedocs.ioA machine learning library that extracts, parses and restructures raw scholarly documents such as PDFs into structured XML/TEI-encoded data, focused on technical and scientific publications.
Code-Graph-RAG
code-graph-rag.comA tool that parses a multi-language codebase with Tree-sitter, builds a knowledge graph of its structure in Memgraph, and lets a developer query, edit and optimize the code in plain English.
Knowledge Graph Builder
llm-graph-builder.neo4jlabs.comAn application that transforms unstructured data such as PDFs, documents, text files, YouTube videos and web pages into a structured knowledge graph stored in Neo4j using large language models.
GenAI Stack
github.comA starter stack combining LangChain, Neo4j and Ollama with Docker, meant as a template and set of demo applications for building a GenAI application.
RuoYi AI
doc.ruoyiai.chatAn enterprise-grade AI agent platform offering multi-provider LLM management, RAG-backed knowledge bases, visual workflow orchestration and multi-agent coordination.
UltraRAG
ultrarag.github.ioA low-code RAG development framework built on the Model Context Protocol, letting a developer assemble retrieval-augmented-generation pipelines from independent MCP servers and orchestrate them with YAML.
Semble
minish.aiA code search library built for AI agents that returns exact relevant code snippets using roughly 99% fewer tokens than a typical grep-and-read search.
Yuxi
xerrors.github.ioA self-hosted, multi-tenant knowledge agent platform combining RAG, a knowledge graph, multi-agent orchestration, MCP/Skills, a sandbox and permission management in one workspace.
Unstract
unstract.comAn LLM-driven platform that extracts structured JSON from unstructured documents such as PDFs, scans and images, deployable as an API or an ETL pipeline.
RAG chat app with Azure OpenAI and Azure AI Search
azure.microsoft.comA sample application demonstrating a ChatGPT-style, Retrieval-Augmented Generation experience over a company's own documents, using Azure OpenAI and Azure AI Search.
DeepSearcher
zilliztech.github.ioAn open-source deep-research tool that combines large language models with vector databases to search, evaluate and reason over private data and produce a sourced report.
The Mother of AI Project
github.comA hands-on course that builds a production-grade retrieval-augmented-generation research assistant from scratch, called the arXiv Paper Curator, teaching keyword search first and then hybrid and agentic retrieval.
Local Deep Research
github.comA self-hosted AI research assistant that runs agentic, multi-step research across many LLMs and more than ten search engines, including private documents, with proper citations.
PaperQA2
futurehouse.gitbook.ioA high-accuracy retrieval-augmented-generation package for answering questions from scientific PDFs, text, Office documents and source code, with citations back to the source passages.
Xberg
docs.xberg.ioA polyglot document-intelligence engine that extracts text, tables, metadata and structured data from more than 100 file formats and code from hundreds of programming languages, with OCR, transcription and 15 language bindings.
PixelRAG
arxiv.orgA retrieval system that renders web pages, PDFs and images as screenshots and searches over the images directly, keeping visual structure such as tables and charts that text extraction would lose.
Orama
docs.orama.comA full-text, vector and hybrid search engine and RAG pipeline that runs in the browser, on a server or at the edge, with typo tolerance, facets, geosearch and a plugin system.
All-in-RAG
datawhalechina.github.ioA full-stack, hands-on tutorial on retrieval-augmented generation for large-model application developers, covering data preparation, index construction, advanced retrieval, generation and evaluation.
CocoIndex
cocoindex.ioAn incremental data-indexing engine that keeps context such as codebases, meeting notes, inboxes, Slack, PDFs and video continuously fresh for AI agents and LLM apps, recomputing only what changed.
BISHENG
bisheng.aiAn open-source, enterprise-focused LLM application DevOps platform combining a visual generative-AI workflow builder, retrieval-augmented generation, agents, model management, evaluation and fine-tuning.
BGE
bge-model.comA one-stop retrieval toolkit for search and retrieval-augmented generation, providing a family of open embedding, reranking and multimodal-search models known as BGE.
Claude Context
github.comAn MCP plugin that adds semantic code search over an entire codebase to Claude Code and other AI coding agents, storing embeddings in a vector database instead of loading whole directories into context.
txtai
neuml.github.ioAn all-in-one Python framework for semantic search, LLM orchestration and language-model workflows, built around an embeddings database that combines vector search with graph and relational storage.
llmware
llmware-ai.github.ioA framework for building local, private, enterprise retrieval-augmented generation applications, pairing a catalog of 300+ small, optimized language models with document parsing and knowledge-base pipelines.
