Screenplay Editor vs Final Draft vs Celtx

Screenplay Editor is built by Hugo Thomas, a French screenwriter and filmmaker whose work includes Willy 1er (Cannes 2016) and Juniors (Netflix). It launched in December 2024 and has grown to more than 14,000 writers, with strong adoption in film schools.

The idea is simple: you already write in Google Docs, so the software comes to you. The Chrome extension recreates the Final Draft workflow live in your document: you press Enter and Tab, and scene headings, characters and dialogue format themselves as you type. The Google Docs add-on brings the full sidebar suite to any browser. Both share the same principle: no new app, no import, no export, your script is a Google Doc from the first day.

Beyond formatting, it includes a Scene Board, a title page generator, a Boneyard for cut scenes, a one-click AI production breakdown, a table read with a different AI voice per character, and PDF and .fdx export. You start free with daily limits, and Pro is $5.99 a month for the Google Docs add-on, or $7.99 for the Chrome extension. Your script stays in your Google Drive: we never store it, we never train on it.

Best for: Writers who collaborate, write on more than one machine, or simply love Google Docs. Students and classrooms, since it runs on Chromebooks with nothing to install.

Final Draft has been the industry standard for decades, and its .fdx file format still rules the professional world. If a production company asks for your script, they often ask for a Final Draft file.

It is also a $249.99 desktop program that has not fundamentally changed in twenty years. There is no real browser version, no real-time co-writing, and your script lives on one computer (with Final Draft's own cloud sync as an option). Many professionals keep it for the final delivery step and write elsewhere.

Best for: Writers inside studio pipelines where .fdx delivery is contractual, and people who prefer a dedicated desktop app. See the full Screenplay Editor vs Final Draft comparison.

Celtx is not really a screenwriting tool: it is a pre-production platform that happens to include one. Breakdowns, stripboards, scheduling, budgeting, shot lists: if you run a production, that breadth is the point.

If you just want to write, it is a lot of platform to carry, and the subscription starts at $29 a month. Your script also lives on Celtx's servers, inside their ecosystem, and leaves it by export.

Best for: Small production teams that want writing and planning in one paid place. See the full Screenplay Editor vs Celtx comparison.

If your work requires .fdx delivery into a studio pipeline, keep Final Draft for the last mile: that is what it is for. If you run productions and want planning tools attached to your script, Celtx earns its subscription.

For everyone who mostly needs to WRITE, alone or with a co-writer, Screenplay Editor gives you professional formatting inside the tool you already use, with real-time collaboration Google Docs invented, for a fraction of the price. And because it exports .fdx, choosing it does not close any door.
