Strata

Strata, a semantic layer for AI applications, launched on Hacker News, presenting itself as an expressive interface that can reject invalid or unanswerable requests from large language models. The product positions itself as a control layer between LLMs and data, enforcing what queries are allowed. Early engagement on the launch is modest, with developers weighing in on its approach to governing AI access to data.

Developer Ajo has launched Strata, a semantic layer designed to give large language models structured, governed access to business data. He says his four years at Netflix working on self-service analytics for non-technical users shaped the product's distinctive design. A notable feature is that Strata can refuse LLM requests that violate its semantic rules, aiming to keep AI-driven data queries accurate and safe.
