What is a synthetic being?

A short definition

A synthetic being is a character with three abilities: it sees, it remembers and it acts. It perceives the place it is in, whether that place is a game level, a dashboard or a network. It keeps a memory of the people it meets and the things that happened. And it takes the next step on its own, within limits that a human sets.

The word “synthetic” is deliberate. A being is made, not born, and it should say so. On this site the guide introduces herself as a synthetic being, her voice is labelled as AI-generated, and she is drawn as the structure beneath the skin rather than as a photograph of a person.

Where the idea came from

Emersa started in London in 2023 as a games studio. We were unhappy with how characters in games behaved: scripted, forgetful and lifeless. A character would greet you the same way on the hundredth visit as on the first, and forget you the moment you walked out of the room.

In 2024 we gave our characters memory, perception and intent. They remembered the player, read the room and acted on their own. People stopped calling them NPCs.

By 2025 the characters had outgrown the games. A character that can see, remember and act is useful wherever people need guidance, and that is most workplaces. We gave the idea a name.

How a being differs from a chatbot

A chatbot waits for text and answers with text. A being has a place and a body. In practice the differences are these:

• It is situated. It knows what is on the screen, which step of a procedure you are on and who else is in the room.
• It is continuous. A conversation is not a fresh start every time. What the being learned about you last week is still there, and you can see it and erase it.
• It is embodied. A being has a face that moves with its speech and a posture that shows attention. People read faces faster than they read paragraphs, and trust follows.
• It can act. Within a policy, a being can open the next screen, fill a form or walk you through a diagnosis, with reversible steps and an immutable audit trail.

Two beings, one lineage

Emersa makes two of them today. Emily Wilson is the enterprise hologram assistant: an ambient, agentic assistant that sees your dashboards, remembers your procedures and walks your people through them. Krupiq guards networks by laying a living decoy over them.

They share one lineage of code: the same rendering, the same memory model and the same rules about consent and honesty.

What a being is not

A being is not a person and never pretends to be one. It does not replace the human who stays in the loop for sensitive actions. And it is not a black box: what it remembers is yours to see and yours to erase, and every version passes evaluation gates before it ships.
