RAG
Reviewed resources in RAG. 540 resources listed.
GibRAM
docs.gibram.ioAn in-memory knowledge graph server for retrieval-augmented generation that stores entities, relationships and document chunks together with their embeddings so related information stays connected during retrieval.
abstracts-search
github.comA project that indexes more than 200 million academic publication abstracts from OpenAlex into a semantic search engine, using embeddings and a fast vector index.
FLAMEHAVEN FileSearch
flamehaven.spaceA self-hosted retrieval-augmented-generation search engine that indexes 34 file formats with hybrid BM25 and semantic search, and can call Gemini, OpenAI, Claude or a local Ollama model to answer from the retrieved passages.
SR-Agents
sr-agents.github.ioA benchmark and toolkit for skill-retrieval-augmented LLM agents that treats reusable agent skills as a large corpus to retrieve from, rather than listing every skill in the prompt.
RAG AI Agent Backend
youtube.comA minimal FastAPI backend that demonstrates retrieval-augmented generation with vector similarity search, built for learning and for wiring into a frontend.
Document Copilot
github.comAn example internal AI chatbot, built for a fictional investment research firm, that lets analysts query a corpus of financial filings in plain English and get sourced answers.
AI Agent Platform
github.comAn enterprise Java AI agent server, built on Spring Boot and LangChain4j, combining ReAct reasoning, hybrid retrieval-augmented generation, and semantic caching for knowledge Q&A.
Vera
github.comA local code search tool for developers and AI agents that combines BM25 keyword search, vector similarity and cross-encoder reranking, returning symbol-bounded results instead of whole files.
OpenDocuments
joungminsung.github.ioA self-hosted retrieval-augmented search platform that indexes GitHub, Notion, Google Drive, Confluence, and other sources into one AI-searchable knowledge base with cited answers.
A research method that lets an autoregressive video generator retrieve its own earlier generated frames as extra context, reducing drift and error buildup in long videos without retraining.
German-OCR
german-ocr.deA vision-language model fine-tuned specifically to extract structured text from German business documents such as invoices, receipts, and forms, runnable locally or through a cloud API.
Eon
github.comAn LLM-powered Slack bot that answers questions using a company's own Slack history, GitHub pull requests, and Linear issues, run on a Postgres and TimescaleDB backend.
GNO
gno.shA local knowledge engine that indexes a folder of notes, code, PDFs, and Office documents, then answers questions with citations through a CLI, web UI, REST API, or MCP.
Local LLM PDF OCR
ahnafnafee.devA tool that turns scanned PDFs and images into searchable documents by reading them with a locally run vision language model instead of traditional OCR.
QINCo2
github.comA neural vector compression method for large-scale similarity search that predicts each quantization step's codebook from a neural network instead of using a fixed one.
terraform-genai-retrieval-augmented-generation
registry.terraform.ioA Terraform module that deploys a generative-AI retrieval-augmented-generation solution on Google Cloud, provisioning a choice of Cloud SQL MySQL, Cloud SQL PostgreSQL, AlloyDB or Cloud Spanner as the database and prebuilt frontend and retrieval service containers.
OneRAG
github.comA production-ready Python and FastAPI retrieval-augmented-generation framework that swaps vector databases, language models, rerankers and caches with a one-line configuration change, running as a full Docker API server or as an offline local CLI chatbot with no API key required.
Open GENAI
github.comAn unofficial project that runs Japan's Digital Agency GENAI government AI entirely locally, replacing cloud dependencies with SAML authentication through Keycloak, an OpenAI-compatible backend, RAG through Qdrant, and local transcription and image generation.
ESEILANE
eseilane.orgA high-performance knowledge graph engine built for large language models and GraphRAG, using sparse matrix algebra for sub-millisecond graph traversals, with full OpenCypher query support and Python, JavaScript and Docker access.
Online Embeddings Matching
github.comA Google Cloud Platform sample that demonstrates real-time text semantic search end to end, extracting embeddings with the Universal Sentence Encoder and building an approximate nearest-neighbour index with the Annoy library.
LumoKit
github.comA Swift package for building on-device retrieval-augmented generation pipelines, combining a document-parsing library with a vector store and semantic search into one end-to-end pipeline for creating a searchable knowledge base on iOS or macOS.
CrossCoder
github.comA research framework for repository-level code generation that retrieves context from external libraries as well as the local repository, using a knowledge graph over both.
th0th
github.comA self-hosted semantic search and memory layer for AI coding assistants that indexes a codebase with local embeddings, aiming to cut context tokens by around 98 percent, installable via Docker or from source and integrated through an MCP client.
DocMason
youtube.comA repo-native agent that turns private office documents such as decks, spreadsheets, PDFs and emails into a local, evidence-first knowledge base, preserving structure like slide layout, table references and formatting so an AI agent's answers stay traceable to a source file.
