Exordium

Slay the blank page.

One place to build an entire world, then write the story that lives inside it. For writers, designers, and game masters.

That’s 14 active days of use, not 14 days on the calendar. The clock only ticks on days you actually open the app. No account, no card.

Exordium's hero: a blond warrior raising a blade, ready to slay the blank page.

Worldbuilding

Build worlds from the ground up

A 14-step studio takes you from a blank slate to a living world, before you write a single word. Mix templates to blend two cultures into one, watch a completeness radar fill in, and it all flows into the map automatically.

The tone & atmosphere radar mapping a world onto sixteen genre axes.
Calendar & astronomy: a custom year wheel of months and seasons.
Planes of existence arranged as an orbital cosmology.
Races & species cards with lifespans and scaled silhouettes.
Religions & pantheons: faith cards with type and founding myth.
Distribution: painting races and religions across the world map per settlement.

Cartography

A map that thinks like a world

Procedurally generate a fantasy world or load real Earth geography, then paint borders, provinces, and settlements, and click any settlement to assign and inspect its data.

A generated fantasy world map: dozens of named nations and their provinces, each region coloured by its political entity.
Settlement · Draeblain · Exordium
A settlement detail panel over the world map: Draeblain's population, wealth, defense, culture, language, religion, currency, world placements, demographics, and a racial-composition pie chart, with a hover tooltip on the map showing type, population, province, and culture.
  • Generate fantasy continents (paint your own landmasses first) or start from real-world Earth data.
  • Political entities with succession, militaries, economies, and trade routes, each deriving its culture, religion, and language from its people.
  • Settlements with per-race demographic pie charts, industries, markets, crime, and legal profiles.
  • Capture historical snapshots ("Fall of the Old Empire") and watch borders and powers shift across eras.
  • Export your map to PNG up to 16K (16384px), print-ready.
Characters

Characters who feel like people

A 7-step character studio builds psychologically grounded people from the inside out, birthplace and era, mind, wounds, resources, and story role.

Character builder, Basic Info tab: name, identity and the essentials.
Character builder, Background tab: birthplace on a world map and the years that bracket a life.
Character builder, Psychology tab: the character's mind and temperament.
Character builder, Inner Conflict tab: the wound, the lie they believe, desire versus need.
Character builder, Resources tab: what the character has to work with.
Character builder, Arc & Role tab: the character's story function and how they change.
  • Core wound, the lie they believe, desire vs. need, public mask vs. private self, depth, not stat blocks.
  • 150+ named archetypes across 14 categories, applied as overlays onto existing characters.
  • Generate a whole ensemble from a description, including AI-assigned relationships between every pair.
  • Shape every relationship's emotional tone on a drag-to-sketch radar, and a force-directed map ties the whole cast together.
Relationship · Exordium
The relationship editor: a drag-to-sketch emotional-shape radar, affectionate, trusting, devoted, deriving a written description of the bond.
Timeline

Plot it on a timeline

Build multiple story timelines from 42 structural templates, then keep your outline beside every scene as you write.

Story Timeline · Exordium
A Hero's Journey story timeline: a gold tension curve of beat nodes rising and falling across three acts, with a beat-detail card open on Resurrection.
  • 42 templates, Hero's Journey, Save the Cat, Kishōtenketsu, Corruption Arc, Political Intrigue, and more, or start blank on a free-form beat canvas.
  • AI generates beats in phases: concepts, per-beat detail, then assigns your characters to each beat.
  • A side panel in the editor shows each scene's beat: a story-function radar, promise/payoff threads, and adjacent beats.
  • Per-scene beat-progress tracking keeps your scenes ordered within the structure.
The editor

Write inside your world

A rich-text editor that recognizes every character, place, and deity from your world as you type, with local-AI autocomplete and a prose-analysis radar.

Chapter One · Exordium
The Exordium editor: a manuscript with entity-aware highlighting and a character card on hover (Bilbo, a Mentor), beside the Textual Harmony analysis panel, a radar scoring the prose at 92.1%, a craft verdict, and specific issues to fix.
  • Entity-aware highlighting: characters, settlements, factions, and deities underlined by role, click a name to open their profile.
  • Inline ghost-text autocomplete from your own local model, Tab to accept, Esc to dismiss.
  • The Textual Harmony radar scores your prose on stylometric axes and pinpoints the passages to fix.
  • Hundreds of craft snippets, a dictionary/thesaurus, conlang translation, and exports to PDF, DOCX, Markdown, and TXT.
  • Compile a full World Bible PDF, every section, map plate, and character, in one click.
