The complete author's toolkit

Every craft a novel needs,
on one desk.

Nine disciplines that usually mean nine apps and three subscriptions. In Edda they share a single, offline workspace, so the world you build is always one click from the sentence you are writing.

Manuscript

An editor built for the long haul.

A fast, clean writing canvas that holds a whole novel without ever feeling heavy.

  • Parts, chapters and scenes in a drag-and-drop tree, each with synopsis and status, and parts that fold away
  • A full word processor toolbar (fonts, colours, spacing, indents, lists, styles) on a page with margins you set, plus markdown shortcuts, footnotes, inline comments, and find and replace
  • Distraction-free typewriter mode, automatic saving a few seconds after you stop typing, and crash recovery
  • Voice dictation, nine editor themes plus a theme builder, and export to PDF, DOCX, Markdown, HTML or text

Writing modes

Twelve kinds of writing, one desk.

Pick a mode when you start a project and the editor changes to fit the form, with the same story bible, goals and backups behind it. Novel, screenplay, sitcom, stage play, audio drama, podcast, comic, academic, interactive fiction, picture book, poetry and lyrics.

  • Screenplay editor with industry formatting, revision colours, a runtime estimate, and Fountain and Final Draft import and export
  • Poetry with 47 forms plus free verse, from haiku and sonnet to villanelle, with live syllable counts and refrain checking
  • Song lyrics with sections, chord charts, transposing, rhyme help and ChordPro export
  • Academic writing with footnotes, endnotes, citations and a bibliography; interactive fiction with Twine export

Worldbuilding

Keep an entire universe straight.

Characters, places and lore that stay consistent across a series, and link to the page you are writing.

  • Character profiles with arc stages, flaws, motivations and custom fields, in rich text
  • Two-way relationships on a relationship web: add Parent on one character and the other shows Child
  • Locations, lore articles and a searchable encyclopedia by category, with tags on everything
  • Custom calendar systems with invented eras, months, moons and festivals on a timeline
  • Multi-generational family trees, maps with markers and image galleries
  • A continuity engine that flags contradictions, and Campaign Mode for game masters

Campaign Mode and continuity

Keep a whole world consistent.

The same engine checks a ten-book series or a three-year tabletop campaign, and tells you when the facts stop adding up.

Continuity engine

Flags a character in two places at once, scenes before a birth or after a death, events out of dependency order, places used before they are founded, and characters acting on facts they have not learned yet.

Campaign Mode

Session prep with encounters and hooks, factions, recaps and handouts, for any tabletop system. Prep and continuity, not a virtual tabletop.

Fact graph

Record who knows what and when they learned it, then see it drawn as a graph: what the party knows against what the game master knows.

Structure and plot

Ten ways to shape a story.

Start from a proven framework, then bend it to your book.

  • Templates for Three-Act, Hero's Journey, Save the Cat, Five-Act, Freytag's Pyramid, Story Circle, Snowflake, Seven-Point, Romance and Mystery
  • Editable beat sheets you place on scenes, and your own templates saved for the next book
  • Give every beat an intensity, then see every plot, subplot and arc on one story timeline
  • The timeline shades stretches where tension sags and flags threads that go quiet
  • Outline view to collapse, expand and reorder parts, chapters and scenes

  • 135 hand-curated prompts and 160,000 combinatorial premises
  • Inline spell check with a per-project dictionary that travels with your manuscript
  • Six readability scores and 16 style-flag categories, from passive voice and hedges to 270+ clichés
