Early-access planning workspace for playable story worlds
Duper is being designed to draft the story bible, characters, game loop, scenes, trailer outline, and soundscape from one editable world source.
Built for prototypes first: story structure, playable loop design, scenes, trailer direction, and target-dependent export notes.
Through the gate
World stack preview — concept preview
Native CSS motion keeps the layered world metaphor while avoiding WebGL and Remotion runtime cost on the landing page.
Story seed, image, clip, or lore.
Rules, characters, places, and choices.
Loop, objectives, scenes, and interactions.
Beats, shots, sound, and edit notes.
Production notes — 01 / The engine
Premise, references, tone, conflict, and open questions stay in one editable source.
Physics, factions, limits, geography, and continuity rules are recorded before scenes multiply.
Roles, motives, visual direction, dialogue notes, and playable constraints are drafted together.
Objective, player action, feedback, success state, and failure state are reviewed as a loop.
Shots, beats, scene order, captions, and edit rhythm come from the same world plan.
Ambient palette, effects, voice direction, music cues, and rights notes stay attached to the world.
Production notes — 02 / Prompt to output
Turn a world seed into objectives, core loop, first level beats, and review notes before production.
First review packet: objective, character, level shell, and loop risk.
Keep storyboard, scene list, character consistency, trailer beats, and sound direction tied to the same story source.
First review packet: storyboard, scene list, consistency sheet, and trailer beats.
Expand lore into map regions, NPC motives, quest branches, and soundscape notes without breaking the world rules.
First review packet: map logic, NPC motives, quest branches, and audio notes.
Reel 01 — Questions on record
Duper is positioned for playable prototypes, story worlds, assets, scenes, trailers, and structured game logic. Production readiness depends on export target and project scope.
Early access focuses on planning outputs first: story bible, character sheets, scene lists, level outlines, trailer beats, and audio notes.
Early access planning can include sound effects, ambient soundscape notes, voice direction, dialogue, and music cues; generated or licensed assets require separate rights review.
Single-output tools are useful for clips, images, or assets. Duper is designed around the whole creative loop: story, world, gameplay, cinematic video, audio, iteration, and export.
