The result to aim for
Romain Finet, plumber-heater in Grenoble (TPF company), dictates to the AI the estimate of PAC when leaving the customer: what took him 2 to 3 hours in the evening passes to about 10 minutes, after rereading.
What was done
InterFast (Hedi Marinier, 13 October 2026) transcribed the live of 6 October 2026. Finet ("Roma the plumber") describes a three-step circuit: the AI resumes the reports of intervention poorly filled by the employees; a model estimate by type of intervention; generation from the report, or dictated on the phone. For 5 to 6 appointments, the preparation goes from 2–3 hours to ~10 minutes the next day, with rereading. He also had 3 balance sheets, 700 quotes and reports analysed: the installation of heated flooring was sold at a loss; the price has been raised of about 25 €/m2. Reported figures, not audited. Distinct from Jeannolin / Cornec / Ekoalu. 1/3 on this URL.
