Corvus

Multi-agent AI research system — finds academic papers via semantic search & citation snowballing, then answers questions over them using agentic RAG with self-reflection. Built with LangGraph, FastAPI, Celery, and Qdrant. Maintained by YS0meone on GitHub, where it has earned 94 stars from the community.

It's actively developed around academic-research, agentic-rag, ai-agent, and is a solid reference for anyone building with these tools.
