The free plan is limited to one project, and Writer supports up to three. Paid plans start at $11.24 per user per month with annual billing, and the trial lasts seven days. The cloud product runs in a browser, while Screenplay is available for Windows and Android; the platform list also includes iOS and macOS. Before switching, weigh whether you need Celtx’s script formats and production workflow, or would benefit more from a different project model, document tools, publishing features, or platform mix.
