The result to aim for
Sylvain Roux, head of a farm of more than 50 hectares in Valréas, uses ChatGPT for his letters, the certifications of the wine union, his accounting reconciliations and cost simulations.
What was done
According to Vaucluse Agricole (article of 12 November 2025), Sylvain Roux, 46, manages the EARL Ferme Roux de l'Enclave (vignes, squash, cereals, sunflower, alfalfa). Dyslexique, he had his letters corrected by ChatGPT and wrote in five minutes the publications and certificates of the wine union. Its accounting software processes twelve recurring invoices in less than five minutes. Blocked for days on a supplier account, he submitted his statements to ChatGPT and reconciled it in two minutes. He simulated for the Cuma federation the cost per hectare of two harvesters, asked about the right time to bring boron to the sunflower, used the vocal mode, and was even used to estimate a crowd from photos. Next step: to exploit its protein data at harvest. His advice: always check the sources.
