Worth knowing

Story Architect

  • The pricing page shows prices on annual billing only; 1-, 3- and 6-month terms exist, but their prices are not listed there.
  • Sync covers desktop apps for now: the pricing page lists mobile sync as in development.
  • Corkboard, timeline, mind maps and extended statistics need Pro; collaboration and script breakdown need Creator.
  • The software is pre-1.0: the desktop apps are at version 0.8.3 and the mobile apps at 0.2.0, with several features still planned.

WriterDuet

  • The Free plan is limited to three projects of one document each, and free users can add only read-only collaborators.
  • The desktop app and offline writing with auto-sync are listed from the Plus plan up.
  • Revision tracking and production tools start at Pro, and full line and document history is Premium-only.
  • Cards cannot be edited or rearranged in the mobile app or in phone and tablet browsers; WriterDuet recommends a computer for them.

Key features

Story Architect

Editors for several story formats
Separate editors for screenplays, comics, audio dramas, stage plays and novels apply industry-standard formatting, with Tab and Enter switching between paragraph types.
Shared project bible
Characters, locations and worlds are described once and shared by every story in a project, including all episodes of a series. Pro adds relationship editors, maps and extended profiles.
Corkboard and timeline
On Pro, screenplays and novels get a card board and a timeline. Cards can be colour-tagged and grouped by act, and changes show up in the script text and the reverse.
Mind maps
A mind map tool for brainstorming and planning is part of the Pro plan, alongside an image gallery and presentations.
AI Assistant
Paraphrases, shortens, expands, summarizes, translates and generates text using credits; one credit covers 1,000 words or 10 images. Extra credits start at $10 for 50.
Sync and collaboration
Creator adds 5 GB of cloud storage, sync and real-time co-writing. Co-authors can join on any plan, with editing limited to the modules their own plan includes.

WriterDuet

Real-time co-writing
Paid subscribers can invite any number of WriterDuet users, free or paid, to edit a script live, with comments, mentions and text and video chat.
Script formats and templates
Keyboard-driven formatting follows industry conventions for screenplays, stage plays, sitcoms and A/V scripts. Pro adds custom margins, line types and title pages.
Cards, outlining and mind map
Each scene can be viewed as a card and dragged into a new order, and a mind map view lets cards be placed freely and linked.
Revisions and production tools
Pro tracks revisions with accept and reject, shows deleted text, and adds colored revisions, locked pages and scene omission for scripts in production.
Saving, history and backups
Work saves to the cloud as it is typed, with automatic backups to a computer, email, Dropbox, Google Drive or iCloud. Premium can rewind a document or a line to any earlier point.
Import, export and narration
Imports and exports PDF, Final Draft, Fountain, Celtx, docx and other formats. Premium's ReadAloud voices each character, and AutoTranslate covers more than 80 languages.
