Does Tessa replace our reliability engineer or turbine technician?+
No. Tessa provides documentation search and citation for the existing team. Engineers and technicians retain diagnosis, judgement and control-setting decisions.
Is my documentation private?+
Yes. Uploaded manuals and procedures are isolated per customer, never used for training, and stay within your team's own library.
What if the manuals are scans?+
Scanned pages are read and indexed page-by-page, so citations point to the exact scanned page image alongside the document and page number.
What happens when the answer isn't in the docs?+
Tessa says so: "Not found in your documents"—instead of guessing—and escalates the question to a named human rather than inferring from general turbine knowledge.
Can Tessa make engineering or safety decisions?+
No. Engineering judgement, safety decisions and any changes to control settings remain human-only; Tessa only ever returns what is written in your own documents.
What result do we measure?+
One agreed scoreboard: citation accuracy, cite-rate, not-found accuracy and documentation search hours returned. No generic "AI transformation" metric.
