I am looking for a screenwriting software that allows for real-time collaboration.

Yes. If real-time collaboration is a priority, I’d focus on these:

• writerduet.com — Best overall for collaboration. It’s built around co-writing: multiple writers can edit simultaneously, see changes instantly, use comments/replies, and even text/video chat inside the app. It also works in a browser and offers a free starting tier.
• arcstudiopro.com — Best modern alternative. It has Google-Docs-style real-time collaboration, inline notes, draft management, writer assignments, and deadlines. It also has a free tier.
• finaldraft.com — Best if industry-standard formatting matters. Final Draft 13 supports simultaneous real-time editing and collaboration on the script and Beat Board. The catch is that collaborators need the same Final Draft version.

My recommendation

If two or more people will regularly write together, I'd choose WriterDuet. It's probably the closest match to "Google Docs for screenwriting."

If you're writing professionally and expect to exchange scripts with producers, agents, or production companies, Final Draft is the safer long-term choice because of its widespread industry use and production-oriented features.

If you tell me (1) Mac/Windows/iPad, (2) how many writers, and (3) whether you need free or paid, I can narrow it down to the best 1–2 options.

The best screenwriting software with real-time collaboration like Google Docs is WriterDuet , alongside strong alternatives like Arc Studio Pro.

If you'd like to narrow this down, let me know:

• Do you prefer a web-based browser app or a desktop installation?
• Are you working on a budget or looking for professional studio features?

It offers a limited free tier to test out.

• Celtx: A cloud-based platform where scriptwriting is paired tightly with pre-production and budgeting tools . It supports real-time multi-user editing, making it popular for indie production teams and student projects who want the crew looking at breakdowns and script updates concurrently.
• Final Draft: The legacy Hollywood industry standard has incorporated real-time collaboration features into its newer versions .

Yes. If real-time collaboration is the key requirement, I’d narrow your search to these:

My top recommendation: WriterDuet

If two or more people will actually sit down and write the screenplay simultaneously, I would start with WriterDuet. It lets multiple collaborators see each other's changes instantly, and it has built-in text/video chat and comments. It also maintains detailed revision history.

It also has a free starting option: its current site advertises three free projects, with no credit card required.

When I'd choose Final Draft instead

If you're writing something intended for a professional film/TV production and want the most established screenwriting software, Final Draft 13 is worth considering. Its collaboration feature supports simultaneous editing of the script and Beat Board. The important catch is that everyone collaborating needs the same version of Final Draft.

The short version

• Best pure collaboration: WriterDuet
• Best professional/industry-standard choice: Final Draft
• Best modern/cloud experience: Arc Studio
• Best for a larger production team: Celtx

If you tell me how many people will be collaborating, whether you're on Mac/Windows/iPad, and whether you're willing to pay, I can narrow this down to the best 1–2 options and compare their current pricing/features.

Best options

Why I especially recommend WriterDuet: it was designed around collaborative writing. Multiple writers can edit the same screenplay simultaneously, see each other's changes, use comments/replies, and communicate through text/video chat. It also keeps revision history and works across computers and mobile devices.

Its free plan lets you create three projects. The Plus plan adds unlimited projects and real-time collaboration; notably, only one co-writer needs a paid subscription for real-time collaboration, so your collaborator can use a free account.

Final Draft is worth considering if you're concerned about industry compatibility. Final Draft 13 supports simultaneous real-time collaboration on the script and Beat Board, although collaborators need compatible Final Draft 13 versions.

My recommendation

• Two people writing together remotely: WriterDuet
• Professional/industry-standard workflow: Final Draft
• Clean, modern interface with strong outlining/story tools: Arc Studio
• Writing + planning the actual film production: StudioBinder

If you tell me whether you're writing with one other person or a larger writers' room, and whether you're on Mac, Windows, or Chromebook, I can narrow this down to the best 2–3 choices and compare their current pricing/features.
