Free screenwriting software formats your script to industry standard as you type, so scene headings, dialogue and action land in the right place automatically. Desktop apps suit writers who work offline, while online editors suit co-writing and notes. Before you share a script widely, understand what registration does and doesn't protect.
Script formatting looks simple until you try to do it in a normal word processor. Margins, character names and scene headings all have rules, and screenwriting software handles them for you.
Here are nine free screenwriting tools in no particular order, sorted alphabetically, from open-source desktop apps to online editors with free plans. Each description comes from the tool's own website, re-checked today. If you're scripting short videos for your business, my talking-head teleprompter script template is a quick way to start.
You don't have to be writing a feature film. The same tools work brilliantly for video ads, explainers, podcasts with sketches and YouTube series. A neatly formatted script also makes life easier for anyone you hire to film or voice it, because they can see at a glance who says what and where each scene happens.

What script registration does and doesn't protect
Here's a misunderstanding that trips up a lot of writers. The Writers Guild of America West Registry says registering your work documents the claim of authorship and does not take the place of registering with the US Copyright Office, which documents ownership. Both can be used as evidence, but they're not the same thing.
So if your script matters commercially, look at both. And keep dated drafts, emails and notes, because a clear paper trail helps whichever route you choose.
What to check in free screenwriting software
- Formatting: does it handle scene headings, dialogue and transitions automatically?
- Export: can you export a clean PDF and a file other apps can open?
- Free limits: how many scripts or pages can you write for free?
- Collaboration: can a co-writer or producer leave notes?
- Offline: can you write without an internet connection?
How to start a script the right way
- Write a one-sentence summary of the story before anything else.
- Outline the main scenes in a list.
- Draft quickly without stopping to edit.
- Read it aloud, or get friends to read the parts.
- Revise, then export a PDF with a title page.
Script mistakes new writers make
- Describing camera moves. Leave those to the director.
- Huge blocks of action. Keep paragraphs short and visual.
- Characters who all sound alike. Read the dialogue aloud.
- Never finishing. A rough complete draft beats a perfect first act.

My plain advice on free screenwriting software
Don't spend weeks choosing software. Formatting is the easy bit now, and every tool here gets it right. The hard part is finishing a draft, so pick the app that feels nicest to open every morning and get writing. If you co-write, choose together, because swapping files between different apps is where formatting goes wrong.
And save versions with dates in the file name. It's the simplest record of your work there is.
Frequently asked questions
Is there free screenwriting software?
Yes. Several open-source apps and online editors with free plans format scripts to industry standard.
Do I need special software to write a screenplay?
No, but it saves a lot of fiddling with margins and layout.

It's a plain-text way of writing scripts that apps can turn into formatted screenplays.
Can I co-write a script for free?
Some online editors let two people write together on a free plan.
Should I register my script?
Registration can help as evidence of authorship. Copyright registration is a separate step.

Lengths vary by genre, so check the expectations of whoever you're submitting to.

Some online editors work in a mobile browser or have apps.
What comes after the first draft?
Read it aloud, get feedback, then rewrite the scenes that drag.
Do I need a title page?

Can I import a script from Word?
Many screenwriting apps can import plain text or common script files, though you may need to tidy the formatting afterwards.
