ddai

Before AI can stand beside people, it needs a character and a way to judge.
ddai designs both.

The world ddai is building

For a humanity that now lives with AI,
we bring the humanities into artificial intelligence
to create conversations between people and AI worth having.

What we do

How we work

  • 01

    Design

    We turn character, voice, and judgment into specs your team can build with.

  • 02

    Localize

    Native writers in each language write from the same spec, from scratch.

  • 03

    Verify

    We score every language, before and after every model change, against one rubric.

Three crossroads where ddai stands

  • Humanities × technology

    Methods from linguistics, psychology, and narrative, turned into specs and evaluation data.

  • Academia × industry

    We read the latest lab research and turn it into product decisions.

  • Research × product

    We build new methods like PersonaOS on ten years of running commercial services.
