AI Pastier: branding expertise you can talk to

AI product developmentViral voice experience

The context

Michal shared that companies were already photographing or scanning his Yellow Book to create their own virtual Pastier. Together with Stanislav Vojtko, we built AI Pastier with Michal’s involvement, making his branding expertise accessible through a conversation. The agent drew on his Yellow Book of Brand Building, his methods, and his approach to thinking about brands.

The work

People could talk to AI Pastier about their brand direction, naming, distinctive brand elements, and marketing challenges. We launched the public beta on 17 November 2025. My work focused on the technical implementation that made those conversations possible, working with Stanislav and Michal to bring the idea to life.

An idea people wanted to talk to

AI Pastier became a viral project that gave people a new way to use Michal’s expertise. The pilot showed people spending time in conversations and coming back with more questions. We took an expert’s body of work and made it something people could talk to about their own business.
