Celtx is free media pre-production software designed for creating and organizing media projects like screenplays, films, videos, stageplays, audio plays, documentaries, machinima, comics, games and podcasts.

The client-server application gives independent filmmakers and media creators an integrated and non-linear approach to the pre-production work phase, providing support for industry standard scriptwriting, story development, storyboarding, script breakdowns, production scheduling and reports. It also allows writers to attach images, videos, and audio files to a project, and provides features for collaborating with others online.

Celtx is built on open, non-proprietary standards (ie. HTML, XML, RDF and TXT ). It is licensed under the Celtx Public License, which is the Mozilla Public License with an attribution provision.

Celtx is an acronym for Crew, Equipment, Location, Talent and XML.
