Collaborative screenwriting tool

Powerful writing, planning and outlining software


Online script collaboration

Celtx allows you to organise, plan and share workflow related to your project, whether it's a script for a film, production notes for a videogame, or any number of other creative ideas.

User interface

When you first sign up to Celtx, you're asked to input your industry, experience and team size. You can then choose which type of project you'd like to open, plus upload an existing script. The workspace is sleek and uncluttered, with helpful tips to make the experience as painless as possible.


Celtx offers real-time collaboration, a project command centre, team permission settings and dedicated customer support and training. There's an exchange to find collaborators, and the Production tab opens up existing projects from other users. Everything is geared towards partnership.


All the above features are available in the free version of the software but, as you'd expect, there are paid subscriptions with additional features. There's a scriptwriting package that includes script, screen and stage play formats, and an offline mode.

Next, a Video Production plan with a shot list, breakdown and scheduling options. Finally, the Game Production plan contains interactive features. Every subscription supports up to 10 projects.

A robust project management tool

The software can seem daunting at first, so there are also extensive guides to help you get to grips with your project. The free version contains enough features for a small team of creatives, but if you run a sizable business, you'll need one of the subscription plans.

Celtx runs smoothly in most browsers, but especially Google Chrome and Mozilla Firefox. Although there is similar production software available (eg. Writerduet and Trelby), Celtx is easily one of the best.
