Hi HN I’m Kaif, the creator of Semantica.

After working on real-world RAG and agent systems, I kept seeing failures caused not by models, but by missing semantics — entities, relationships, rules, and provenance. Vector-only pipelines often look fine in demos but break silently in production.

Semantica is an open-source attempt to make semantic structure a first-class layer alongside vectors and LLMs.

I’d love feedback from folks running RAG / GraphRAG / agent memory in production or regulated domains. Happy to answer technical questions or discuss trade-offs.
