Canon engine
A living story bible
Capture universes, characters, places, items, relationships, tone, and lore once, then reuse that context across every project.
Canon-aware creative production
Sekaiko is yourAI story studio.
Sekaiko helps creators turn a fictional universe into finished work. Build the canon, organize characters and locations, generate text and media with shared context, then carry everything into books, films, scenes, edits, and publishable assets.
Canon-aware AI
Books, movies, scenes, and cuts
Text, image, video, audio, and 3D media
What Sekaiko does
One workspace for canon, generation, and production.
Most AI tools start with an empty prompt box. Sekaiko starts with your world: the lore, cast, relationships, references, drafts, and generated media that make a story feel consistent. The result is a studio where planning and making happen in the same place.
AI generation
Create media from the same source of truth
Generate and refine text, images, video, audio, voices, 3D models, and splats without rebuilding context from a blank prompt every time.
Production workflow
Move from idea to structured output
Plan books and movies, break them into chapters or scenes, storyboard shots, assemble cuts, and keep the work organized as it grows.
Performance
Build characters that can speak and act
Use character context, voice IDs, multi-speaker scripting, audio generation, and lip-sync workflows to turn dialogue into performances.
Media library
Keep every reference connected
Save uploads, generated assets, prompts, tags, galleries, and reusable references to the universe or entity they belong to.
Distribution
Prepare work for the places it goes next
Export media, publish finished pieces, and connect social workflows for YouTube and TikTok when your project is ready to leave the studio.
Design a living universe.
At the heart of Sekaiko is the Universe: the source of truth for your fictional world. It stores the rules, tone, cast, locations, objects, reference art, and long-running continuity that every project depends on.
Because the AI can work from that structure, it can draft scenes, prompts, dialogue, and media with the right people, places, props, and history already in view.
Universe
Canon for your world
Define the premise, rules, genre, tone, and recurring lore once. Every book, movie, scene, and asset can draw from the same foundation.
Characters
Cast with memory
Track identity, motivations, relationships, images, voices, and arcs so dialogue and behavior stay coherent across episodes and drafts.
Places
Locations with texture
Map cities, starships, rooms, realms, and sets. Scenes can pull the right visual and narrative details instead of reinventing each location.
Items
Props that matter
Track artifacts, gear, evidence, heirlooms, and plot devices with ownership, meaning, and continuity attached.
From universe to finished project.
A Project is where your universe becomes a concrete piece of work: a book, film, episodic series, scene pipeline, or media production built on top of shared lore.
Sekaiko keeps the creative material close to the production material: drafts, chapters, storyboards, generated images, clips, cuts, audio, references, and final exports can all stay connected to the same story structure.
Books
Chapters, scenes, and editions
Organize long-form writing into chapters and scenes, use context-aware drafting, and keep supporting media alongside the manuscript.
Movies
Scenes, storyboards, and cuts
Build scene lists, generate storyboard frames and clips, stage references, edit cuts, and prepare final video outputs.
Media pipeline
Images, video, audio, and 3D
Generate, upload, edit, upscale, crop, tag, and reuse creative assets without separating them from the story decisions that shaped them.
Continuity
Structure instead of version chaos
Keep project context, drafts, prompts, references, and generated outputs tied to the canon so revisions do not drift away from the world.
Pricing
Storage plans for the studio. Credits for generation.
