WriterDuet

WriterDuet is a writing application tailored for screenwriting, book, and other text formats. One of its strongest assets lies in the real-time collaboration features.

It is true that many traditional writing tools do not allow concurrent collaboration. However, there are still some famous apps that do so successfully. Google Docs is an example; it has established a high bar for facilitating collaborative writing and editing. So, what distinguishes WriterDuet from these word processors? Here is the answer: it helps authors format their writings in compliance with cinema and television standards.

While WriterDuet's advantages are undeniable, there are still drawbacks. For once, the monthly fee is very costly. Its levels of payment plans are also rather perplexing. The app only allows you to create 3 scripts for free (with some restrictions included). In these cases, you cannot ask others to work in real-time with you; also, it is impossible to back up your data to personal storage.
