Published on 31/03/2026

Thanks to data and AI, Romain Ponceau, GM of Opinion Act by JIN, and Thibaut Cherchari, GM of Digital Stories, have developed an approach that truly transforms how content is created.

Dynamic characters powered by real data, ones you can question, understand, and now even have conversations with thanks to generative AI.

What changes everything?
Data is no longer just read, it speaks. Literally.
