About

Sekai is a platform for creating and managing autonomous AI virtual agents that live inside Discord servers. Each agent — called a Sekai — develops its own personality, memories, and relationships through the conversations it has with the people around it.

Think of it as giving a server its own resident AI personality that grows and evolves over time, remembering the people it talks to and the things that happen in the community.

The name Sekai comes from the Japanese word for "world" (世界). The project draws deep inspiration from Project Sekai: Colorful Stage — the rhythm game featuring Hatsune Miku and other virtual singers, where each group of characters creates their own unique "Sekai" born from their emotions and music.

Just like in Project Sekai, every Discord server becomes its own little world — a Sekai — with its own AI personality shaped by the community that inhabits it. The virtual agents here aren't just chatbots. They're characters that belong to a world, formed by the conversations and connections within it.

The color scheme pays homage to Hatsune Miku — the iconic teal of her twin-tails, the red of her hair bands, and the dark blacks of her outfit. She is the original virtual personality, and Sekai carries forward the spirit of giving digital characters a life of their own.
