Golden Nebula

Golden Nebula is a universe builder for fiction writers who want to shape worlds, cast characters, plan scenes, and keep their manuscript moving — all stored locally and offline. Built for writers who think in story bibles, not just blank pages.
Worlds — create world bibles with genre, core premise, and lore rules that keep your fictional universe consistent. Each world shows a readiness percentage and lets you deepen lore or open the full bible. Track multiple projects side by side, from cosmic fantasy to political intrigue.
Characters — character sheets with desire, arc, and wound for every cast member. The conflict matrix shows tension levels and active scene counts across your full cast at a glance, so you always know which relationships are carrying the most dramatic weight. Resolve story beats or open a full sheet for deeper work.
Scenes — turn story beats into draftable cards with point of view, conflict, outcome, and word targets. Each scene tracks words drafted against its target and shows completion percentage. Add words directly from the card or mark a scene fully drafted when it's done.
Prompts — a prompt forge with saved seed cards for lore, character voice, tension, transitions, and sensory detail. Each prompt tracks how many times you've used it and your practice depth over time. Save the prompts that work and unsave the ones that don't.
Progress — manuscript-wide stats combining word count, number of worlds, cast size, and scenes completed. Set writing goals per project, like a draft sprint or an opening act polish, and track remaining words against each target as you log sessions.
Golden Nebula is for fiction writers who want their worldbuilding, characters, and manuscript progress to live in one connected system — not scattered across notebooks and documents.
