Show HN: Ragpi – Open-Source AI Assistant for Chatting with Your Developer Docs

1 point

a year ago

I’ve been working on Ragpi, an open-source AI assistant that builds knowledge bases from docs, GitHub Issues and READMEs. It uses PostgreSQL with pgvector as a vector DB and leverages RAG to answer technical questions through an API. Ragpi also integrates with Discord and Slack, making it easy to interact with directly from those platforms. Some things it does:

- Creates knowledge bases from documentation websites, GitHub Issues and READMEs

- Uses hybrid search (semantic + keyword) for retrieval

- Uses tool calling to dynamically search and retrieve relevant information during conversations

- Works with OpenAI, Ollama, DeepSeek, or any OpenAI-compatible API

- Provides a simple REST API for querying and managing sources

- Integrates with Discord and Slack for easy interaction

Built with: FastAPI, Celery and Postgres

It’s still a work in progress, but I’d love some feedback!
