STRAIGHT ANSWERS

You've got questions. Fair enough.

Is Rudy here to replace me?

No. Rudy is a research tool that makes you faster and more prepared. You still diagnose, you still fix, you still make the call. Rudy just makes sure you walk into every job with the right specs, the right procedures, and the page number to prove it.

Can I actually trust AI answers on safety-critical equipment?

Every answer cites its source — document name, section, page number. You can verify anything against the original OEM material before you act on it. Safety warnings are injected automatically whether you asked about safety or not. If Rudy doesn't have a confident, sourced answer, it tells you.

I've been doing this 20 years. What does AI know that I don't?

Probably nothing about your specialty. But can you hold tens of thousands of pages of manuals in your head across every make and model? Rudy isn’t smarter than you — it just has perfect recall. And when you need to cite a spec to a customer or your boss, Rudy gives you the exact page number so you look like you always knew.

What happens when Rudy gets something wrong?

You flag it. One tap. Your correction goes into a review pipeline and, once verified, improves every future answer on that topic. Corrections from proven experts are trusted more — top contributors earn auto-approval. Rudy gets smarter because of people like you—not in spite of them.

Does it work on my equipment?

CAT, Cummins, Kohler, Generac, MTU, Detroit, Perkins — 127+ manufacturers and counting, with the deepest coverage in power generation. And when coverage is thin, Rudy tells you instead of guessing.

What about when I have no signal?

Rudy installs on your phone like an app — no app store needed. Offline manual caching is rolling out now: cache your equipment's docs before you leave the shop and read them anywhere. You'll need a signal to ask new questions.
