Quivr
RAG & knowledgeAn open-source RAG framework and "second brain" for chatting with your files and data.
Quivr began as a "second brain" app and has become an opinionated RAG framework: a small core that handles the common retrieval pipeline so developers can stand up a document assistant quickly.
It aims for a gentle on-ramp — sensible defaults, little configuration — while staying open-source and embeddable.
Where it's ideally used
A fit when developers want a lightweight, opinionated RAG core to embed without designing a pipeline from scratch.
Where it doesn't fit
The opinionated defaults get in the way once you need deep control over chunking and retrieval strategy.
