Looking for a free screenplay editor online? We compare the best browser-based and free screenwriting tools available in 2026 no downloads, no subscriptions, just write.
Finding a free screenplay editor online is easier than it used to be. A few years ago, serious screenwriting software meant buying Final Draft or pirating something. Today there are genuinely good browser-based tools that format your script to industry standards at no cost.
This guide covers the best free online screenplay editors available in 2026 what they offer, where they fall short, and which one is right for you depending on how you work
Before comparing tools, it helps to know what actually matters. A good free screenplay editor should:
The CineFormat AI web app is a dedicated browser-based screenplay editor with live formatting built in from the first keystroke. Open it in any browser — no account, no installation, no sign-up and your script is formatted automatically as you type.
It recognizes all standard screenplay elements: scene headings (INT./EXT.), action lines, character cues, dialogue, parentheticals, and transitions. Each element gets the correct industry-standard style applied immediately.
When you're ready, export a properly formatted PDF (Courier Prime 12pt, correct margins, page numbers) or a Final Draft .fdx file.
What makes it stand out: Most free online editors either require an account or restrict exports to paid tiers. CineFormat AI lets you write and export without either barrier.

WriterDuet is a cloud-based screenwriting tool with a strong free tier and genuine real-time collaboration. Two or more writers can work on the same script simultaneously, with changes syncing instantly. It works in the browser and has dedicated apps for desktop and mobile.
The free tier limits the number of scripts you can keep active, but for a single project it works well.

Trelby is a free, open-source screenwriting application for Windows and Linux. It is not browser-based — it requires a download — but it is completely free with no feature restrictions and no paid tier. It supports PDF export and .fdx export, and has a clean distraction-free interface.
If you prefer a desktop application and don't want to pay anything, Trelby is a solid choice. The trade-off is that it is no longer actively developed and the interface feels dated.

Google Docs alone cannot format a screenplay correctly. But with the CineFormat AI add-on installed, it becomes a capable free screenplay editor. Write your draft in Google Docs as normal, open the CineFormat AI sidebar, and apply industry-standard formatting in one click.
This combination gives you Google Docs' familiar interface, real-time Drive collaboration, and proper screenplay formatting all for free.

Cons:
Celtx started as a free desktop screenwriting app and has evolved into a cloud-based production suite. The free tier allows basic screenplay writing in the browser with automatic formatting. It also includes tools for pre-production planning, storyboarding, and scheduling useful if you're thinking beyond just writing the script.
The free tier is more limited than it used to be, and some export features require a paid subscription.
Pros:
Cons:
Best for: Beginners who want to explore the full production pipeline, not just writing.
