Celtx is a versatile screenwriting software for the whole pre-production team. It promises a seamless writing experience and provides a range of formatting options and script templates, ensuring adherence to industry standards. Collaborative features such as commenting and client approvals enable multiple writers to work together in real-time. However, what makes Celtx stand out are its production management tools. Once the script has been written, users can keep track of future production expectations through shot lists, script breakdowns, call sheets, and catalog maintenance.
