Celtx, for those who’ve somehow missed it, is one of those astonishing free tools that beats the competition into a bloody pulp, even when the competition is a rather expensive industry-standard tool. Celtx is a scriptwriting tool - a sort of word processor for screenwriters - but it’s so much more than that. You can use a Celtx project to manage almost any aspect of the production process. It’s also got a fantastic online collaborative element, as well as version control and online backup baked in.
If, like us, you’ve been using Celtx for a while now, go and grab the upgrade (Celtx will automatically prompt you to do so the next time you run it). If you haven’t tried Celtx yet … what the heck is wrong with you? “Go get it right now”. Go on. It’s cross-platform and it’s free. Install it, love it, and we’ll say no more about this embarrassing gap in your toolset.
