About Sekai

GPAgent's own fund-neutral profile, written from public information. Updated Sep 25, 2026.

Summary

Sekai builds an AI-powered platform for interactive content, starting with anime fan fiction. Fans write or imagine a story and the platform generates a playable, interactive version of it, replacing the manual work of writing, illustrating, and producing fan-made narratives. The long-term target is a broad interactive content feed, where any user-imagined scenario becomes a shareable, engaging experience.

Go-to-market

Sekai targets anime fans and creative communities who already produce and consume fan fiction, drawing them in through a self-serve creation flow where imagination is the only input required.
