Professional writing software like Final Draft is not necessary when you’re just starting out. There are cheaper alternatives.

We used to recommend Celtx, but since going from free to a paid model and “browser only” interface, we haven’t tried the paid version.

The best free app we’ve seen recently is Trelby, which is a stand alone app for Windows and Linux.

For Mac users, we recommend Highland. It’s based on Fountain, a plain text markup language for screenwriting. For more Fountain-based programs, visit here.

If you’re using any cloud software, it’s important to back up your work to your home PC. Don’t rely on web apps to save your files forever!
