RAG
Reviewed resources in RAG. 540 resources listed.
FirstData
firstdata.deepminer.com.cnA structured, MCP-accessible catalog of authoritative external data sources, government, international-organization, and academic, meant to ground AI agents' answers in verifiable primary evidence.
Academic Deep Search & QA
github.comA local research assistant that searches Semantic Scholar for a topic, filters and summarizes the papers it finds, and answers questions grounded only in that retrieved set.
ZotSeek
github.comA Zotero plugin that adds local, offline semantic search over a research library, plus a built-in read-only MCP server so AI coding agents can search and cite the same papers.
ragnar
ragnar.tidyverse.orgAn R package for building retrieval-augmented generation pipelines, with sensible defaults for chunking, embedding, and storage while keeping every step inspectable.
open-extract
github.comA schema-based extractor that pulls structured data from documents and the web into JSON or Markdown with a single tool call, for use inside AI agent workflows.
DocPaws
github.comA self-hosted RAG document assistant with per-user knowledge bases, PDF indexing, source citations, and a configurable distance threshold that makes it decline out-of-scope questions.
Dataroom
dataroom.hanxiao.ioA self-hosted research harness that turns a query into a comprehensive, fully-cited 'dataroom' of sourced files by running a local model through a search-read-write loop for hours on end.
ShannonBase
shannonbase.orgA MySQL-compatible database that adds vector search, ML model training, local LLM inference and RAG pipelines as native SQL calls, collapsing a typical AI data stack into one engine.
Semantic Search API
semanticsearch.aiA production-ready semantic search API built entirely on Cloudflare's free-tier infrastructure, with OpenAPI documentation and separate reader and writer API keys.
Startup Hybrid Search
github.comA demo search engine over a catalog of startup descriptions that lets a developer switch between semantic, keyword and hybrid retrieval on the same data, built with Qdrant.
context-engine
github.comA pure-Python library that decides what an LLM actually sees from retrieved documents: retrieval, re-ranking, memory decay and token-budget enforcement in one pipeline.
MEM-KB
2023782whl.github.ioA self-hosted knowledge workspace for teams that organizes documents, notes, and a knowledge graph for retrieval-augmented question answering, with built-in RAG evaluation and nightly self-consolidation.
RAG Agent
github.comA local-first retrieval-augmented question-answering system that combines semantic and keyword search with a ReAct agent loop, citation checking, and task recovery after a restart.
Local Multimodal AI Chat
github.comA self-hostable Streamlit chat application that talks to local Ollama models (or optionally OpenAI), with document RAG over PDFs, image chat and Whisper-based voice input.
semble_rs
github.comA Rust command-line tool that replaces grep, cat and ls for AI coding agents, returning hybrid BM25 and embedding code search, a compact codebase tree, dependency and impact analysis, and compressed build or CI logs.
Renumics RAG
github.comA demo retrieval-augmented-generation assistant built with LangChain and Streamlit, intended to explore and visualize the data behind a RAG system rather than serve as a production chatbot.
Nosia
github.comA self-hosted Ruby on Rails platform for running AI models on your own data with an OpenAI-compatible API, retrieval-augmented generation over your documents, and Model Context Protocol integration to connect the assistant to external tools.
SimplyRetrieve
github.comA fully local, GUI and API platform for Retrieval-Centric Generation that lets a user build a private chat tool over their own documents and a locally hosted open-source language model, with a retrieval-tuning module for prompts and analysis.
MemGraphRAG
arxiv.orgA memory-enhanced GraphRAG framework accepted at a 2026 data-mining conference that organizes retrieval into three connected layers, an abstract schema, extracted facts, and source passages, with conflict detection between facts and their supporting evidence.
Knowledge Graph Extractor
hanxiao.ioA self-hosted tool that turns any document, URL, or zip of files into an interactive knowledge graph, extracting subject-predicate-object facts with a locally-run LLM.
TeleOCR
github.comA lightweight, open-source vision-language model, about 1.2 billion parameters, for unified document parsing across both digital documents and camera-captured photos of documents.
Vexor
github.comA semantic search engine for files and code that builds a reusable index and lets a developer or an AI coding assistant find a file by describing what it does, through a CLI, a Python API or an MCP server.
FlexRAG
flexrag.readthedocs.ioAn open-source framework for quickly building, evaluating and reproducing retrieval-augmented generation systems, covering text-based, multimodal and web-accessible scenarios with an end-to-end pipeline from data preparation to evaluation.
jina-grep
jina.aiA command-line semantic grep for Apple Silicon that reranks or searches files by meaning using Jina embedding models running locally through MLX, with no PyTorch or cloud dependency.
