WriterDuet is often likened to the Google Docs of screenwriting. The software enables live collaboration and provides an extensive toolset for professional screenwriters.

But it's expensive: currently, it costs $159 for a lifetime premium license, and on June 1st, the price will increase to $199. However, as a way to promote the upcoming app launch, WriterDuet is now offering the software for $127 for a limited time with promo code WDPRO20 when you buy it here.

Here's a brief rundown of the WriterDuet Pro features:

  •  Desktop application
  •  Dropbox and Google backups
  •  Customizable PDF watermarks
  •  Pin drop and typewriter mode
  •  Save unlimited scripts
  •  Write online or offline
  •  Auto-save to your hard drive
  •  Script statistics and reports
  •  Search and export drafts from any point in history
  •  Real-time collaboration

I've used WriterDuet to collaborate on a script before. With automatic backups to Google Drive or Dropbox and comprehensive versioning, it's a good way to feel secure that your work is being saved, even as multiple writers edit the same document. For solo writers, the intuitive feature set in offline mode is competitive with Final Draft. With export/import to all major screenwriting formats, WriterDuet is another major contender in the screenwriting software space. This is a good opportunity to get a lifetime license at a good price.
