Celtx
A Brief History
Celtx launched in 2008 as a free, open-source desktop app for Windows, Mac, and Linux. For nearly a decade it was the default "free Final Draft alternative" for film school students and indie writers. In 2017, parent company Backlight pivoted Celtx to a web-only, subscription-only product — the desktop app was deprecated and the free tier disappeared. Today, Celtx Studio costs $15/month ($180/year) with no free option.
Celtx File Formats
Two formats are commonly called "Celtx":
- .celtx — the legacy desktop package. A ZIP archive containing
script.html(the screenplay) plusproject.rdf(metadata) and any embedded media. Still in circulation among writers who held onto Celtx 2.x desktop installations. - .html — the modern export from Celtx Studio (the web app). A single HTML file where each screenplay element (scene heading, character, dialogue, parenthetical, action, transition) is a
<p>tagged with a class name.
Why Writers Leave Celtx
- The paywall pivot. A tool that was free for nine years suddenly cost $180/year. Many longtime users felt blindsided.
- Missing modern features. No AI voices for table reads, no per-line voice recording, no video auditions, no digital contract signing, no built-in professional email. See the full MyWriters.life vs Celtx comparison.
- Import friction. Moving Celtx files into other tools historically meant exporting to Final Draft, then importing — and Celtx's FDX export drops formatting on the way out.
Importing Celtx Files into MyWriters.life
MyWriters.life imports both .celtx packages and Celtx Studio .html exports natively — no conversion through Final Draft, no manual cleanup. Scene headings, characters, dialogue, parentheticals, and transitions all map cleanly into our editor, and the rest of the platform (AI voices, storyboard, casting, contracts) is yours from there.
