# Haiku RAG
[![Tests](https://github.com/ggozad/haiku.rag/actions/workflows/test.yml/badge.svg)](https://github.com/ggozad/haiku.rag/actions/workflows/test.yml)
[![codecov](https://codecov.io/gh/ggozad/haiku.rag/graph/badge.svg)](https://codecov.io/gh/ggozad/haiku.rag)
Agentic RAG built on [LanceDB](https://lancedb.com/), [Pydantic AI](https://ai.pydantic.dev/), and [Docling](https://docling-project.github.io/docling/).
## Features
- **Hybrid search** — Vector + full-text with Reciprocal Rank Fusion
- **Reranking** — MxBAI, Cohere, Zero Entropy, or vLLM
- **Question answering** — QA agents with citations (page numbers, section headings)
- **Research agents** — Multi-agent workflows via pydantic-graph: plan, search, evaluate, synthesize
- **Document structure** — Stores full [DoclingDocument](https://docling-project.github.io/docling/concepts/docling_document/), enabling structure-aware context expansion
- **Visual grounding** — View chunks highlighted on original page images
- **Time travel** — Query the database at any historical point with `--before`
- **Multiple providers** — Embeddings: Ollama, OpenAI, VoyageAI, LM Studio, vLLM. QA/Research: any model supported by Pydantic AI
- **Local-first** — Embedded LanceDB, no servers required. Also supports S3, GCS, Azure, and LanceDB Cloud
- **MCP server** — Expose as tools for AI assistants (Claude Desktop, etc.)
- **File monitoring** — Watch directories and auto-index on changes
- **Inspector** — TUI for browsing documents, chunks, and search results
- **CLI & Python API** — Full functionality from command line or code
## Installation
**Python 3.12 or newer required**
### Full Package (Recommended)
```bash
uv pip install haiku.rag
```
Includes all features: document processing, all embedding providers, and rerankers.
### Slim Package (Minimal Dependencies)
```bash
uv pip install haiku.rag-slim
```
Install only the extras you need. See the [Installation](https://ggozad.github.io/haiku.rag/installation/) documentation for available options
## Quick Start
```bash
# Index a PDF
haiku-rag add-src paper.pdf
# Search
haiku-rag search "attention mechanism"
# Ask questions with citations
haiku-rag ask "What datasets were used for evaluation?" --cite
# Deep QA — decomposes complex questions into sub-queries
haiku-rag ask "How does the proposed method compare to the baseline on MMLU?" --deep
# Research mode — iterative planning and search
haiku-rag research "What are the limitations of the approach?" --verbose
# Interactive research — human-in-the-loop with decision points
haiku-rag research "Compare the approaches discussed" --interactive
# Watch a directory for changes
haiku-rag serve --monitor
```
See [Configuration](https://ggozad.github.io/haiku.rag/configuration/) for customization options.
## Python API
```python
from haiku.rag.client import HaikuRAG
async with HaikuRAG("research.lancedb", create=True) as rag:
# Index documents
await rag.create_document_from_source("paper.pdf")
await rag.create_document_from_source("https://arxiv.org/pdf/1706.03762")
# Search — returns chunks with provenance
results = await rag.search("self-attention")
for result in results:
print(f"{result.score:.2f} | p.{result.page_numbers} | {result.content[:100]}")
# QA with citations
answer, citations = await rag.ask("What is the complexity of self-attention?")
print(answer)
for cite in citations:
print(f" [{cite.chunk_id}] p.{cite.page_numbers}: {cite.content[:80]}")
```
For research agents and streaming with [AG-UI](https://docs.ag-ui.com/), see the [Agents docs](https://ggozad.github.io/haiku.rag/agents/).
## MCP Server
Use with AI assistants like Claude Desktop:
```bash
haiku-rag serve --mcp --stdio
```
Add to your Claude Desktop configuration:
```json
{
"mcpServers": {
"haiku-rag": {
"command": "haiku-rag",
"args": ["serve", "--mcp", "--stdio"]
}
}
}
```
Provides tools for document management, search, QA, and research directly in your AI assistant.
## Examples
See the [examples directory](examples/) for working examples:
- **[Interactive Research Assistant](examples/ag-ui-research/)** - Full-stack research assistant with Pydantic AI and AG-UI featuring human-in-the-loop approval and real-time state synchronization
- **[Docker Setup](examples/docker/)** - Complete Docker deployment with file monitoring and MCP server
- **[A2A Server](examples/a2a-server/)** - Self-contained A2A protocol server package with conversational agent interface
