## About SHIM
SHIM is a lightweight middleware that sits between your application and your LLM provider. It solves the two biggest pain points of running AI in production: data privacy and cost. Every API call passes through SHIM, which automatically detects and redacts personally identifiable information — names, emails, phone numbers, and more — before it ever reaches the model. This keeps you GDPR and KVKK compliant without rewriting a single line of your existing code. SHIM's smart caching layer goes beyond exact-match lookups. It understands the semantic meaning of queries, so when users ask similar questions, cached responses are served instantly instead of burning tokens on redundant API calls. Teams typically see a 40% reduction in their LLM spend. Built for developers shipping RAG pipelines, customer support chatbots, and internal AI tools where data protection and cost control aren't optional — they're requirements.
