Worldbuilding

Build rich, deeply interconnected worlds that breathe life into your stories. From character backstories to custom calendars, every detail of your universe lives in one place.

Living Characters

Create characters with depth -- detailed profiles, evolving arcs, tangled relationships, and visual galleries that keep your cast vivid and consistent.

Places & Lore

Map out locations with descriptions and significance. Build an encyclopedia of lore, magic systems, history, and cultures that underpins your entire narrative.

Custom Systems

Define your own calendar with eras, months, and historical events. Build family trees, track lineage, and connect every element with tags and notes.

Character Profiles

Characters that feel real

Every great story is driven by unforgettable characters. Edda gives you structured profiles with every attribute you need -- name, role, age, appearance, personality traits, backstory, motivations, and flaws -- so you never lose track of who your characters truly are.

No more scattered notes or forgotten details. When your protagonist's eye color matters in chapter thirty-two, you will know exactly where to find it.

  • Structured fields for name, role, age, and physical appearance
  • Personality, backstory, motivations, and flaws in rich text
  • Custom notes section for anything unique to your story

Arcs & Relationships

Track how characters grow and connect

Characters do not exist in isolation. They grow, they change, they collide with each other in ways that drive your plot forward. Edda lets you map character arcs across your story and define the web of relationships that binds your cast together.

Define relationship types -- ally, rival, mentor, love interest, family -- and add descriptions that capture the nuance. Track how those relationships evolve from the opening scene to the final page.

  • Track character arc stages tied to chapters or plot beats
  • Named relationship types with freeform descriptions
  • See all connections from any character's profile at a glance
Locations

Places your readers will want to visit

Whether it is a crumbling castle on a storm-swept coast or a neon-lit alley in a cyberpunk metropolis, your locations deserve the same care as your characters. Edda gives each location its own profile with rich descriptions, narrative significance, and direct connections to the characters who inhabit them.

When you need to remember which characters have been to the Thornwood or what happened at the harbor in Act Two, everything is a click away.

  • Detailed descriptions with rich text formatting
  • Significance field to capture thematic or plot importance
  • Link characters to locations and see who belongs where

Encyclopedia

Your world's own wiki

Magic systems with their own internal logic. Histories that span centuries. Cultures with traditions, customs, and conflicts. Edda's encyclopedia gives you a dedicated space to write detailed wiki-style articles about every aspect of your world's lore.

Categorize articles by type -- history, magic, culture, religion, technology, legend -- and tag them for fast retrieval. When you are mid-chapter and need to remember the rules of your magic system, your encyclopedia is one click away.

  • Rich text articles for lore, magic, history, and cultures
  • Category and tag system for organized knowledge
  • Quick access from your manuscript while you write
Custom Calendar

Time works differently in your world

Your fantasy world does not follow the Gregorian calendar. Edda lets you define entirely custom calendar systems -- name your eras, create months with any length, and place pivotal events on your timeline. Whether your world has thirteen months, three moons, or a calendar that resets with each dynasty, Edda handles it.

Plot events, festivals, battles, and character birthdays against a timeline that belongs to your world, not ours.

  • Define custom eras, months, and day counts
  • Place historical and story events on your timeline
  • Track festivals, battles, and character birthdays
