“Celtx: If you are a Linux user who is seriously considering
professional screenwriting, then Celtx is your best bet. This free,
cross-platform tool allows writers to create industry-standard
screenplays in a quick, hassle-free manner. And, even though it
comes with great screenwriting features like Revision mode, Text
Lock, Index Cards and more, it is not a dedicated screenwriting
tool. Celtx, in fact, is a media pre-production software that
allows artists to create and organize media projects like
documentaries, audio plays, movies, podcasts and even comic books
and games. However, despite being packed with so many features,
Celtx is a competitive screenwriting software which might become an
industry standard someday.”
