Celtx – The Ultimate Screenwriting Software [Cross-Platform]

Simon Slangen 06-11-2009

celtxA lot of old-school writers and producers still use the familiar pen and paper. Others have migrated to the digital world and are using Open Office or MS Word.


Personally I’ve never felt quite at home in Word to write a story. Instead, I’ve always been using creative writing suites or pre-production packages.

That’s right, there is screenwriting software that’s specifically designed to help you formulate ideas and work in a simple, but flexible creative environment.


I’ve written an article about yWriter yWriter - A Word Processor For Creative Writing Read More in the past, a tool that would help you with outlining and working on your stories. A creative writing suite, if you will. Celtx is different. Oh sure, Celtx will be able to help you with your creative writing, but it’ll do so much more.

Celtx is screenwriting software that aims to aid in all media pre-production. So what does this mean? Whether you’re working on a novel, a film, a comic, a radio or podcast broadcasting, or even a video game, Celtx will help you put down those ideas and help you plan them in a quick and efficient manner.



With all types of features and support, you won’t have to jump over and through between five different screenwriting software applications anymore (if you even used any). Everything can be written, planned and colaborated from within Celtx.

Below we’ll take a look at some of the most prominent features in the application. Believe me, if you’re in the creative business, this is one application you’ll want to add to your arsenal.

Writing Suite

For the storytellers, Celtx comes equipped with the same basic tools you’d expect and a few more advanced ones as well. With a place to list your characters, locations and the like, you don’t have to worry about losing track again. When outlining a story, you can also use the storyboard feature you’ll be discussing below. One cooks with the ingredients at hand, and in our case there’s a buffet already laid out.


One of the most important aspects of Celtx – and its greatest features – is the ease with which one can embed other types of media. If you feel the need to add a picture, drawing or movie fragment to your work, or even an mp3, you can do so with a few clicks of the mouse. One of the reasons I prefer to use the Celtx screenwriting software sis that it doesn’t try to force you into certain ‘development roads’. You can use your own creative way to get at your destination.


In the writing category, Celtx comes with a few different editor flavors: Screenplay, stageplay,  AV scripts, audio play, comic book and text. It doesn’t matter in what branch you’re working, Celtx does not discriminate.


I have already mentioned the storyboards. Although you can indeed use them when you’re writing a novel, they’re much more commonly used in film production.


Create different sequences and easily add individual pictures and drawings, or even do a batch import. Label and narrate your pictures to create a detailed and intricate storyline. If you want, you can even specify the camera shot you intend to use.


Drag and drop groups of images to change the order of events. When you’re done (for the moment), print the pages or share them with your partners. If you want you can even play them in a full screen diashow.

Believe me, this doesn’t even begin to describe what Celtx can do. I’ve been using a lot of software, but this is certainly one of the most amazing screenwriting software suites I’ve ever seen.

    It does not seem to be open source. They do offer the source of an old version as a tarball, but I can't find the source for the latest version, no nightly builds, no repository...
    Smells like proprietary software to me.

      That might well be. That said, I don't think I ever said anything about it being open sourced.
