indexio 0.1.1

Lightweight semantic indexing and retrieval for project knowledge sources

indexio

Lightweight semantic indexing and retrieval for project knowledge sources for prompt and context engineering.

Indexes document sources (markdown, code, etc.) into a ChromaDB vector store and provides semantic search. Standalone library — no knowledge of projio or other ecosystem packages.

Install

pip install indexio
# or editable from source:
make dev

Quick start

# Write a starter config into your project
indexio init

# Build the index
indexio build

# Query
indexio query "how does authentication work"

# Show store status
indexio status

indexio status compares the current source matches to the last build manifest and groups sources into buckets such as indexed, changed, and not yet built.

Chat server

A built-in RAG chatbot backend and embeddable widget.

indexio owns the chat API, demo page, and widget assets. projio owns site-builder-specific mounting for ecosystem docs sites.

# Install with chat support
pip install indexio[chat]

# Start the chat server
indexio serve

# With a custom LLM
indexio serve \
    --llm-backend openai --llm-model gpt-4 --llm-base-url https://api.openai.com

Open the URL printed by the server, such as http://localhost:9100/. If that port is already in use, indexio serve will automatically pick the next free port and print it.

Embed the widget directly in any docs site:

<script>
  window.INDEXIO_CHAT = {
    apiUrl: "http://localhost:9100/chat/",
    title: "My Docs Assistant",
    storageKey: "myproject_chat_v1",
  };
</script>
<script src="http://localhost:9100/chatbot/chatbot.js"></script>
<link href="http://localhost:9100/chatbot/chatbot.css" rel="stylesheet">

Settings are also configurable via INDEXIO_CHAT_* environment variables.

If your project uses projio to build docs sites, prefer enabling chatbot injection there instead of wiring the widget tags by hand.

Python API

from indexio import load_indexio_config, build_index, query_index

cfg = load_indexio_config(".indexio/config.yaml", root="/path/to/project")
build_index(config_path=".indexio/config.yaml", root="/path/to/project")
results = query_index(config_path=".indexio/config.yaml", root="/path/to/project", query="embeddings")
