Now through August 31, Screencraft is offering a lifetime license of WriterDuet Pro for $149, a $50 savings off the regular price. The lifetime license offers free access to all future upgrades.

We've written about WriterDuet before; it's an online, real-time collaborative screenwriting software application that lets multiple writers work on the same script at the same time. WriterDuet also features several additional tools, such as group video and group messaging, to make the writing process truly collaborative no matter where you or your writer partners live. Here's a quick video overview of WriterDuet's key features:

WriterDuet continues to offer a free online version of its collaborative screenwriting software, which we have recommended in the past. Basic features include online access to WriterDuet, revision tracking, and import/export capabilities to multiple screenplay and document formats. The basic version limits users to three scripts and the application is only available via an internet connection.

WriterDuet Pro builds on the basic features and provides the following additional capabilities:

  • Desktop application for offline writing
  • Dropbox & Google backups
  • iOS and Android mobile apps
  • Customizable PDF watermarks
  • Script shortening tools
  • Pin drops to mark specific spots in scripts
  • Typewriter mode to keep the cursor in the center of the page as the script is written/edited
  • Save unlimited scripts
  • Compatible with Mac, PC, iOS and Android, online and offline
  • Auto-save to hard drive
  • Script statistics and reports
  • Search and export drafts from any point in the script's revision history
