SHIM – Secure AI gateway that reduces LLM costs and protects data

Summary: SHIM is middleware that redacts personal data and cuts OpenAI expenses by 40% using Smart Caching and prompt normalization. It acts as a secure interface between applications and LLM providers, preventing data leaks and reducing redundant query costs.

What it does

SHIM detects and redacts PII such as emails and credit cards before data leaves the server. It uses Semantic Caching to answer repeated queries from a local cache, eliminating extra costs and latency. It also supports switching LLM providers dynamically and provides usage observability via a dashboard.

Who it's for

Developers building AI applications who need to control costs and ensure compliance with data protection regulations like GDPR.

Why it matters

SHIM prevents accidental exposure of sensitive user data and reduces expensive repeated LLM queries, addressing compliance risks and cost inefficiencies.
