About semantic-coverage
Semantic-coverage is an open-source Python tool that automatically detects knowledge gaps and blind spots in RAG vector stores. It analyzes the semantic coverage of a vector store to identify areas where the stored embeddings lack sufficient representation.
Best for
Developers building RAG systems who need to programmatically check vector store coverage and identify gaps.
Use cases
- Audit a RAG vector store for missing or underrepresented topics
- Identify blind spots in retrieval before deploying a RAG system
- Validate the completeness of a knowledge base used for retrieval-augmented generation
Notes
12 stars on GitHub. Last updated 2025-12-24.

- Open source with a permissive license
- Lightweight Python library easy to integrate into existing pipelines
Cons
- Very early stage with only 12 GitHub stars and limited community
- No documented support for non-Python environments
- May require manual tuning or additional tooling for production use
