SenaryumSenaryo Okulu's screenwriting tool

Screenwriting Software (In Your Browser, No Install)

Senaryum is Senaryo Okulu's screenwriting tool: it runs in the browser and needs no installation. As you type it recognises what kind of line you're writing (slug line, action, character, dialogue) and sets the indents for you. When you're done, you get a PDF with a title page, ready to send.

What Senaryum gives you

You write without fighting the format

It recognises slug lines, action, characters and dialogue as you type and sets the indents itself. It remembers your locations and character names and suggests them next time. You see page breaks as you write, so you always know how long the script runs. On a computer you can leave yourself a note: the note line stays on screen and never goes into the PDF.

You read your script the way a reader will

In Review, scenes are numbered and you find what you're looking for straight away. Save a version, and later you see what you changed without hunting for it.

You get a PDF ready to send

Choose where the script is going (competition copy or reading copy), fill in the title page and download the PDF. You can also see the same text in a two-column layout. After a rewrite, the lines changed since your saved version are marked with an asterisk, and the revision PDF carries only the changed pages.

In the competition copy your name and contact details stay off the title page and scenes come out unnumbered. You enter the page limit of the call you're applying to; Senaryum shows whether the script fits it and reminds you that your name shouldn't appear in the text.

• Scene board: see your whole film as cards and move scenes around.
• Focus mode: only the line you're writing stays on screen, so nothing pulls you away.
• The line's lesson: if you've finished the lesson on a line type, you can open it again from the type menu.
• On your phone too: write a scene the moment it comes to you, then carry on at your computer with your account.
• Your writing stays yours: it isn't shown to anyone.

You build your film before the script, too

Senaryum isn't only a script page; the whole preparation of the film sits in the same project. While you write, you check what a character wants or which act a scene falls in without opening another file.

• Project documents: idea, logline, theme, synopsis, treatment and notes.
• Characters: a card for every character. On the Relationship Map you lay characters out on a board and draw the ties between them; in Character Arcs you write where a character starts, what changes them and where they end up.
• World: rules of the world, locations, research notes and references.
• Structure: Act View, a Beat Sheet where you line up the story's turning points, and a Timeline that covers the backstory too.
• Scenes: on the Scene Board you see the whole film as cards and move scenes around; in Sequences you group them. The Character and Location Report shows which characters speak in which scenes, and lists every location, on a single page.
• Film design: director's statement and notes on visual and sound design.

You write together and talk while you work

With Write together you open your script to one person: you send the link and they join with their account. They read while you write, and it changes on their screen as you type. Hand them the pen and they write; you take it back whenever you like. Only one person writes at a time, so two people's sentences never overwrite each other, and a version is saved at every handover.

While you work you can talk by voice or video: the call opens without leaving Senaryum, with the page in front of both of you. Calls have a monthly time limit, and you see the minutes you have left in the room. You can close the link whenever you like.

It stays fast on long scripts

It doesn't lag on a feature or a TV episode. Senaryum was tested with a 240-scene script: the letter is on screen the moment you press the key. You jump to any scene from the scene strip or the search. There's no limit on pages, scenes or projects.

A screenwriting app: on your phone, on your computer, offline

Senaryum is online screenwriting software: it opens in the browser and you install nothing on your computer, so it works the same on Windows, Mac and Linux. On your phone it lives inside the Senaryo Okulu app, which is on the App Store and Google Play.

On a train, on a plane or when the connection drops, you keep writing. If you've opened Senaryum once while online, it opens without a connection too; your writing is saved on the device and, if you have an account, moves there when you're back online. You can get a PDF ready to send while offline as well. Only importing a script from a PDF file needs a connection.

Using Senaryum: what's included

• You can start writing without an account. Your writing is saved in the browser you're using.
• With an account you download your work, keep versions, open more than one project and pick up where you left off on another device.
• No watermark on the PDF. No limit on pages or projects.
• Besides PDF, you can export your script as Final Draft (.fdx), Fountain and plain text. You can import Final Draft, Fountain and PDF files; your script isn't locked into Senaryum.

What's next for Senaryum

We work on Senaryum every day. We keep updating it with feedback from writers and what we learn from how it's used, and we aim to meet industry standards. We're working on the following and they'll open soon; they aren't available yet.

• Standalone Senaryum apps: desktop and mobile apps for people who only want to write, without the lessons. Senaryum inside Senaryo Okulu will carry on as it is.
• An AI assistant: instant feedback, suggestions and analysis on the scene you've written. It won't write the script for you; it will read what you wrote and show you where it's strong and where it slips.
• Mentoring from professional screenwriters: we're building the groundwork for you to work on your script with an experienced screenwriter.

What is screenwriting software, and what does it do?

Screenwriting software is an editor that lets you write in screenplay format. Every line in a screenplay has a type: slug line, action, character name, parenthetical, dialogue, transition. Each type has its own indent and its own rules. The software knows the line type and sets the indent for you; you only write the story.

In a word processor you do the same job by hand: you set the margins for every line of dialogue, capitalise every character name and watch that a speech doesn't split badly at the bottom of a page. In a short scene that's no problem; in a ninety-page script you spend more time on layout than on writing.

• Format: it lays lines out by type and sets the indents and capitals.
• Pages and running time: in the standard layout one page is roughly one minute of film; because the software shows page breaks, you see the script's length as you write.
• Scene structure: it lists your scenes, lets you move between them and makes reordering easier.
• Versions: it keeps the earlier draft while you rewrite and shows what changed.
• Delivery: it produces a PDF with a title page, in the layout a competition or a producer expects.

What kinds of screenwriting software are there?

Screenwriting programs fall into four groups by the way they work. The difference between them is where your script lives and how you reach the program.

• Desktop programs: Final Draft, Fade In, Highland, Trelby and KIT Scenarist are in this group. The program is installed on your computer and your file stays there; to write on another device you move the file.
• Browser-based programs: WriterDuet, Celtx, Arc Studio and Senaryum are in this group. Nothing to install; whichever device you sign in from, your script is there.
• Word processors: Word and Google Docs aren't screenwriting software, but with a template whose styles are defined you can write in screenplay format.
• Plain-text formats: with a format such as Fountain the script is written as a simple text file, and a program that reads it lays it out.

Paid and free screenwriting software

Screenwriting programs come in four models. The model decides for how long, and on what terms, you can use your script, so it's worth looking at the model before the price.

• One-time licence: you buy the program once and use that version for good. Major upgrades may be charged separately.
• Subscription: you pay monthly or yearly; while it runs the program stays current, and when it ends use may be restricted.
• Free tier plus a paid version: you can start writing, but with limits such as the number of projects, a watermark on the PDF or locked features.
• Open source: programs whose code is public; they're developed by a community and given away free.

Which software do you need at each stage?

A screenplay isn't written in one sitting; it goes through several stages from idea to set, and each stage asks something different of the software.

• Idea and preparation: logline, synopsis, characters. You don't need the format yet; what you need is to pull the idea together. Senaryo Okulu's Film Lab builds your film from these pieces, step by step.
• First draft: you need speed — writing without thinking about the format, getting a scene onto the page before you lose it. In Senaryum the format sets itself as you type, and you can write on your phone too.
• Rewriting: you move scenes around, keep the earlier draft and see what you changed. In Senaryum the scene board and versions are there for this.
• Delivery: the file going to a competition, a fund or a producer should be in the standard page layout, with a title page. Senaryum's Deliver mode produces the PDF for where it's going.
• Set and production: once the film goes into production, the script becomes the crew's working document with scene numbers, breakdowns and revision pages. Senaryum's character and location report shows which characters speak in which scenes, and lists every location, in a single report.
