Teaching a Local AI Agent to Search the Web (Without Lying to You)

Adding web search to a local Mac-based AI agent took months of trial, error, and debugging.

The team kept everything on Apple silicon and off the cloud, but ran into search-engine bot blocks and browser fingerprinting issues.

Bugs also surfaced in the toolchain that parses model output, manages browser sessions, and handles search results.

They eventually shifted to simpler search pages and improved browser identity handling to keep the system working.

The project shows that privacy-preserving on-device AI search is a brittle, multi-part engineering problem, not a single API call.
