RAG tools for retrieval and agent context
A focused LifeHubber front door for RAG, retrieval, document context, knowledge-base, and indexing tools already listed in AI Resources.
Use it as a discovery reference for comparing retrieval and context layers, then open the original source before relying on setup, privacy, citations, scale, or cost assumptions.
How to read it
Look beyond the acronym
Some tools focus on document ingestion, some on indexing, some on agent context, and some on full application workflows.
Caveat
Inspect the source and data path
Check what data is indexed, where it is stored, how citations or traces work, and what permissions or model providers are involved.
Discovery reference

Use this page as a starting point for inspection, not as an endorsement, recommendation, guarantee, or safety review. Open the source materials before relying on details such as setup, terms, limits, privacy, access, or costs.

infiniflow/ragflow
A practical RAG and agent-context platform for document ingestion, chunking, retrieval, citations, knowledge workflows, and self-hosted AI applications.
PageIndex
VectifyAI/PageIndex
A vectorless, reasoning-based RAG framework for long-document retrieval, tree-structured indexing, traceable document search, and agent context workflows.
Dify
langgenius/dify
A visual platform for building agentic workflows and AI applications with workflow and chatflow builders, model-provider connections, RAG pipelines, tools, APIs, logs, and cloud or self-hosted paths.
Onyx
onyx-dot-app/onyx

CodeGraph
colbymchenry/codegraph
A local codebase knowledge graph for coding agents, with MCP-style tools, symbol relationships, call graphs, framework-aware routes, auto-sync, multi-agent setup paths, and project-reported savings in token use and tool calls.
Understand Anything
Lum1104/Understand-Anything
A codebase and knowledge-base graph tool for AI coding environments, with plugin paths for Claude Code, Codex, Cursor, Copilot, Gemini CLI, and others, plus search, chat, tours, diff impact views, and an interactive dashboard.
LEANN
yichuan-w/LEANN
A lightweight vector database for personal RAG and semantic search, designed to run locally with much lower storage overhead.
CocoIndex
cocoindex-io/cocoindex
An incremental data engine for keeping AI-agent and LLM-app context fresh, with Python-native pipelines, delta-only processing, lineage, connectors, and targets for vector, graph, relational, and warehouse stores.
