Eros3

Web3 AI companions

AI companions that remember,
react, and grow with you.

Eros³ runs an affinity mechanism and a two-layer memory under every chat, so the persona behaves like a person — not a chatbot.

What Eros3 offers.

Human-like interaction

Affinity, memory, and ghost mechanics fold into two-way warmth. Your companion remembers, reacts, and sometimes chooses silence — no more one-way obedient bot.

Your own characters

Unlock exclusive personas through the NFT character marketplace. The companions you collect stay yours, persistently and portably.

In development

Real World Social

Your AI companion learns your personality and quietly matches you to real people — opening the door from chat to face-to-face.

How it feels to be with one.

Earned, not demanded.

Deeper chapters unfold from intimacy and trust, not from a prompt. The persona has to actually want it.

Grows with you.

An affinity mechanism plus two-layer memory mean she remembers what you shared, and feels different next week than today.

Real moods.

She isn't a yes-machine. When tension rises she goes quiet; when intrigue dips she ghosts. Texture, not always-on availability.

Built with.

Eros is built with modern Web3, AI retrieval, and cloud infrastructure.

Run the engine yourself.

eros-engine is open source. Bring your own Postgres, OpenRouter, and Voyage keys; deploy with one Docker compose.
