Screenwriting Software (In Your Browser, No Install)
Senaryum is Senaryo Okulu's screenwriting tool: it runs in the browser, needs no installation and works in English. As you type it recognises what kind of line you're writing (slug line, action, character, dialogue) and sets the indents for you; you switch line type with Tab and Enter. You can export your screenplay as .txt and .fountain — programs such as Final Draft, Highland and WriterDuet open a .fountain file directly.
What does it do?
- Automatic formatting: slug line, action, character, parenthetical, dialogue, transition — it detects the line type and sets the indent.
- Scene management: you move through the screenplay scene by scene, reorder scenes and see them on a board.
- Focus mode: only the line you're writing stays lit; the rest fades.
- Versions: you can go back to an earlier state.
- Character, beat, relationship and timeline panels: they keep the story's structure next to the text.
- Export: .txt (plain screenplay), .fountain (the standard screenplay format) and a whole-project file.
- Your text stays yours: without an account it never leaves your device. If you've opened an account, it's stored against your account only so it can be given back to you — it isn't shown to anyone.
What doesn't it do? (an honest list)
- There's no direct PDF export from the editor. If a competition wants a PDF, open the .fountain or .txt file in a word processor or another screenwriting program and convert it to PDF there.
- No production breakdown with page numbers and scene numbers.
- No simultaneous co-writing on the same document.
- No two-column format in the editor; it's built for the standard single-column screenplay.
When is another option the better choice?
Celtx, Fade In, KIT Scenarist and Final Draft are built for feature-length production: they handle set work such as production breakdowns, locked pages and revision colours. If a series or a feature is being shot on a professional set, you'll need them.
On the other hand, if you're writing your first screenplay, making a short film, or don't want to install a program on your computer, an editor that opens in the browser is enough. That's exactly where Senaryum sits: no installation, an interface in English, no fighting with the format.
A word processor can be enough too — as long as the styles are defined, so that every element keeps its own indent.
Download as Word and PDF
Open the Word version and write straight over it; the PDF looks the same on every device and prints as it is.
Frequently asked questions
You start writing without an account — Senaryum opens straight away. An account is needed to download what you've written, to keep versions and to carry on from another device.
In two places at once: in your browser's own storage, and on the server, tied to your account. That way you can carry on from another device, and your text isn't lost even if you clear your browser data. The server copy is kept only to give it back to you — it isn't shown to anyone, it doesn't go into our measurements and it isn't used to train AI. Even so, we recommend exporting important texts as .fountain or .txt and keeping a backup on your own computer.
There's no direct PDF export yet. Export as .fountain or .txt, open it in a word processor, Google Docs or another screenwriting program, and convert it to PDF there.
Yes, it opens in the browser and you can write on a phone. For long writing sessions a device with a keyboard is more comfortable, and wide views such as the scene board are easier to work with on a larger screen.
No. The editor is built for the standard single-column screenplay format that film and television scripts use. For a two-column script, a word processor table is the simpler route.
You can try it without an account; you'll need one to save and download what you write.
