Decades of manuals, spec sheets and resolved tickets held the answer to almost any field problem — but it was scattered, unsearchable on-site, and walking out the door as senior engineers retired. Generic AI tools were a non-starter: the data couldn't leave the network.
An on-prem retrieval agent that indexes the entire corpus and answers natural-language questions grounded in it — every response linked back to the exact document and passage it came from. No cloud calls, no data egress, no hallucinated procedures.
Engineers get a cited answer in seconds instead of trawling PDFs. First-time-fix rates rose, institutional knowledge is captured and reusable, and security signed off because the data never moved.
An answer you can't verify is worthless to an engineer holding a torque wrench. So the agent never just asserts — it shows its working, surfacing the source document and passage behind every response. If the corpus doesn't support an answer, it says so rather than inventing one.
Running on-prem was non-negotiable. The whole system — index, retrieval and inference — sits inside the client's network, so sensitive technical data never touches an external service.
As new manuals and tickets are added, the index updates; the agent gets more useful the more the team uses it.
"It's like having our most experienced engineer on every job — and it shows you the manual page so you know it's right. The fact it never leaves our network is what got it approved."
