WriterDuet is a screenwriting app built around writing together: real-time co-writing, comments and chat, in the browser, on mobile and on the desktop.
Filmara co-writes in real time too, and goes past the page. The screenplay’s characters, places and storyboard live in the same project, and the shots are rendered from the script.
If you want a writing room with production revisions and Final Draft files in and out, WriterDuet is a strong choice. If you want to see the film you are writing, Filmara shows it.

WriterDuet exports Fountain, and Filmara opens it: export the script as a .fountain file and open it in Filmara. Comments and line history stay in WriterDuet.
It works the other way too: Filmara exports Fountain, which WriterDuet imports.
