Collaborative screenwriting: co-write a screenplay in real time

Scenaloom is collaborative screenwriting software: co-writers edit the same script at the same moment in a browser, see who is in the project and leave comments on the exact lines they mean. Collaboration is included on every plan, including Free.

Write in the same draft at the same moment

You and your co-writer work in one script, not two copies that need merging. Edits appear for everyone as they are made, and live presence shows who is in the project.

Because scenes, characters and boards are read from the draft, a scene your partner writes shows up on your scene board too. There is one version of the story, and everyone is looking at it.

Roles and permissions

You decide who can do what. Every project member has a role: owner, admin, editor or viewer. Owners and admins manage access, editors write and comment, viewers read. A producer who only needs to read gets the viewer role and cannot change a line by accident. Members can also carry a craft, such as Screenwriter, so the team knows who does what.

Invite people by email from the project. Each role is described in sharing and roles.

Comments on lines, with replies and @mentions

You get notes attached to the line they are about, not a list in an email. Comment on any line, add an image if a reference helps, reply in a thread and @mention a collaborator to bring them in.

For partners in different time zones this replaces the long notes email: one writer leaves a question on a line at the end of their day, and the other finds it, and answers it, on the same line the next morning.

Version history you can preview and restore

You can always get back to an earlier draft. Save named versions at the moments that matter — the table-read draft, the network draft — preview any version and restore it when you need to. Changes applied from Scenaloom AI are recorded there too. A useful habit is to name versions after who received them, such as "Producer draft, March 3", so restoring later is a choice between labeled drafts rather than timestamps. See comments and version history.

Share links and public read-only pages

You can show the work without handing over the keys. A share link can be set so people with the link can read, so they can make changes or so anyone on the web can view. Nothing is shared until you create a link or publish. You can also publish a public read-only script page, or publish to the Scenaloom community when the script is ready for readers.

Running a writers' room in the browser

A remote writers' room needs one draft, clear permissions and a record of decisions. A practical setup in Scenaloom looks like this:

1. Create the project, invite writers as editors and invite anyone who only needs to read as a viewer.
2. Break the story together on the beat board and scene board.
3. Hand out scenes in comments, with an @mention for each writer.
4. Save a named version before each big pass, so the room can go back.
5. Send a read-only share link to anyone outside the room who needs to read the draft.

Every editor writes in the same layout, so the PDF the room exports is the page everyone saw while writing.

Collaborative screenwriting with nothing to install

A co-writer needs a browser and an invite. Scenaloom runs in current Chrome, Safari, Edge and Firefox on Mac, Windows, Linux and Chromebook, so a partner on a different computer opens the same project. There is no desktop app and no offline mode; everyone writes online. Start a shared project on the Free plan.
