I work as a Boat Captain and I've been building Camera Search for 16 months to provide better tools for tradesmen. It's evolved into a larger platform with multiple clients, but the core use case for me was building a video and photo first agent that is grounded in actual manuals and data and provide better diagnostics, parts, and repair info.
My longterm vision is to be the agent platform for traditional industries, bridging the gap between knowledge work and physical work.
Diagnosis without the professional having to be on site is a good use case.
