CoSpaceGPT replaces in-house RAG with Needle for accurate multi-file retrieval

The problem

CoSpaceGPT needed a robust, highly accurate RAG pipeline to retrieve context across mixed file types and large multi-file workspaces, but their in-house similarity-search approach broke under scale and could not maintain accuracy.

First attempt

CoSpaceGPT's internally built RAG system relied on similarity search over embedded chunks. It worked initially but broke as file volumes grew, failing to handle mixed media and multi-file queries.

output
“it gave us pretty good accuracy”
Reported outcome

CoSpaceGPT found Needle easy to integrate with minimal engineering effort, achieving good retrieval accuracy for their multi-file use case and allowing the team to focus on product improvements rather than infrastructure complexity.
