Celtx is a comprehensive software package designed for people who work in the Film, TV, Theatre and New Media industries. It combines full-feature scriptwriting with media rich pre-production support and enables online collaboration.

Prior to Celtx, projects were completed using slip sheeted, paper based scripts maintained in bulky three ring binders that included hundreds, sometimes thousands, of attached pictures and hand written notes. Project information, in other words, could only be shared in paper form.

Scripts written or imported in to Celtx can be broken down digitally and, for the first time, easily shared with others to foster collaboration and creativity during the pre-production and production phases of film and TV making.
