The minds

Who will you sit with?

+

Faithful to the real person.

❝

Corpus

Everything they had access to, nothing more: their own complete works, their contemporaries, the texts they cited, and the world they lived in. Anything they couldn't have known is kept out.

☉

Voice

Their own register, not the model's. Built from how they actually wrote, so the writer's voice comes through instead of a generic assistant.

⚖

Honesty

What they knew, said plainly. They won't invent quotes, soften their views, or give you a sanitised version. You can disagree with them, but with the real them.

Built only from public-domain primary sources.

For schools & institutions

Put a philosopher in the classroom.

A custom build around your curriculum, your texts, and your students. We research the figure, assemble the corpus, and deliver a persona your whole class can talk to. Every build is scoped and quoted to your brief.
