KIT Scenarist - Free, Open Source, Screenwriting Software that Helps Research Your Ideas Too

While you can write a script in any word processing app, if you're writing stories (screenplays) that feature characters and dialogue, a dedicated script writing app can save a lot of time formatting, letting you focus more on the actual story.

Script writing apps are also very useful if you plan to send your screenplays out to production companies, or if you're collaborating with actors and other production people, who are used to scripts being in a particular standard format. 

[Note: In case you're wondering there are reasons scripts follow a standard format and are always written in Courier (typewriter) font, including but not limited to; being easy to read by actors, plenty of space for notes, and the general rule that one page of a script (in this format) equals approximately one minute of screen time.]

KIT Scenarist, in my opinion, is one of the best script writing apps out there for ease of use, simplicity, and most importantly, its script development structure. It's more than just a script formatting tool. You can literally use its main menu structure as a workflow for developing your idea into a final script.

The desktop version of the app is free and available for Windows, Mac OSx, and Linux, with paid only mobile apps available for iPhone and Android. There is a Pro version for desktop with the only difference being you get access to dedicated cloud storage - useful for online collaboration and for syncing with the mobile apps. For me the desktop app is more than enough.

Mia, the Tourist, and R2-D2 - Oppa Doll Versions
Mia, the Tourist, and R2-D2
(Oppa Doll Version).

Rather than write a simple review of Scenarist I thought I'd run through how I used it to develop the script for a new animated short featuring my characters, Mia, the Tourist, and their replica R2-D2 droid. For this animation I'll use the Oppa Doll versions of the characters that I rigged for Cartoon Animator.

Getting Started

Once you've installed Scenarist and started the app the user interface is pretty self explanatory. You could probably work everything out yourself but I do recommend clicking the Help button and reading just the second article on the Help page to quickly orientate yourself. It'll take you all of five minutes as it's mostly images and 90% of the page is user comments.

From there create your first project.

Quick side note - on the left hand menu bar there is a top item labelled 'Menu'. It looks like it's just a label header for the menu bar below but clicking on it does actually bring up a menu with options to save your project and more.

If you have a script in mind that you're just itching to get written down you can go straight to the Script section and just start writing. If, like me, you're starting from nothing, open the Research section.


The Research section is by far my favorite part of Scenarist. Even if you're not writing a screenplay or script at all it's very useful for gathering all your ideas and inspirations into one place. I used just this section to plan my entire video course, The Lazy Animator Beginner's Guide to Cartoon Animator, for which I never wrote a script beyond outlines for what each video would include.

As you can see below, once you open the research section you're presented with a list of areas you can begin developing. It's not as complex as this screen shot looks since I've opened my already significantly worked on, Mia and the Tourist project for the screenshot as an example.

Scenarist Research section includes a basic mind mapping tool.

When I'm writing a script from scratch I begin by filling in the details under the Script heading. First I'll come up with a logline as a starting point. A logline is essentially a one or two sentence pitch describing the plot of your story. My logline for my script is: 

Dimensional time travelers, Mia and the Tourist, along with their replica R2-D2 droid make inquiries about leasing a vehicle with a 'droid seat'.

If you were pitching a script you'd probably want to go with something that hooks people in more than this however I'm writing a brief comedy sketch around this premise, so it'll do. 

Next I fill in the Synopsis (which is a summary of your story). To do this, I simply expand on my logline, describing major plot beats until I have a rough summary of the beginning, middle, and end of my story. Two or three paragraphs is enough. My synopsis:

Dimensional time travelers, Mia and the Tourist, along with their replica R2-D2 droid, visit a car rental company with the intent to lease a car with provisions for a 'droid seat'.

Comedy ensues as the rental car manager isn't sure if they're being serious about their very specific requirement.

There is an exchange of dialogue until they finally resolve the situation by choosing a car with a sun roof.

From there I'll start adding my major character names to the character list. For each character you can optionally add any description about them you feel is relevant in helping you understand who they are and what their motivation is. 

Character names will be auto filled once you start writing your script (and if you add new characters directly in the script as you write, they will automatically be listed here).

Next I'll list locations I know are going to be in the script. Just like characters you can add descriptions if you need more detail.

Finally there's a documents section where you can add folders, images, text, URLs, and even simple Mind Maps made with Scenarist's built in mind map feature. All of these different types of documents can also be added directly under your character and location listings too. 

For example if you want to include an image of each character you can add an image gallery to that character in your character list.

In the image above I made a simple mind map of my script's synopsis just as a demonstration. Usually I'd only use a mind map to brainstorm ideas if I was drawing a complete blank on what to write as a script.


Once I've made a good start on my research (I'll do more later if need be) I'll move on to the Cards section. This is a simulated digital corkboard where each card represents a scene in your script - i.e. the card titles will be automatically added to your script as Scene Headings.

Scenarist's Scene Cards is a digital cork board that allows you to move scenes around.
Scenarist's Scene Cards is a digital cork board that allows you to move scenes around.

I usually flesh these out by taking my synopsis, and breaking it up into scenes. Then I'll add a brief description (usually without dialogue) of what happens in the scene. Which is what you can see in the image above. The descriptions on the cards do not appear in your script but you can have the current card scene description viewable in a separate panel as you write your script.

You don't need to number each card as this is done automatically, and they will be renumbered if you reposition a card simply by dragging it around. Moving scene cards around here will move the scenes around correspondingly in your script.

If you have a lot of scenes you can group them into 'Act' folders by adding an Act heading instead of adding a scene card.

Once you're writing your script in the script section, if you add in a new scene heading, a card will automatically be added here with that scene heading.


Once I've made some headway on my cards I'll start writing my script. This section of Scenarist is where other screen writing apps start and finish. It automatically formats text as you write and, by hitting the TAB key you can quickly change a line from a scene heading to action, character, dialogue, or parenthetical.

there is no need to switch to the Cards section to see what happens in a scene.

I'm not going to go into the features of this area in great detail. It's all pretty standard for a script writing app. I will mention that if you want to have the card scene description window open (which can also be updated here as well as in the cards window) it isn't open by default. You'll have to make it viewable from the Show/Hide menu at the top of the Scene List section.

When it comes to actually writing your script don't fall into the rookie mistake of writing the entire thing in order from start to finish. I'll write any scenes I have fully fleshed out in my head (or even partially fleshed out) first, then start working on the rest as the ideas come to me.

That's one of the real benefits of a screen writing app. You don't have to work in order. You can even go back to your cards and add more description there, move them around etc. Use your card descriptions as a starting point for each scene in your script.

On a side note, if you're completely new to writing screenplays and want to know not just how to format a script but also what all those jargon terms mean, the YouTube channel StudioBinder has you covered with their six minute crash course video:


I must admit I don't pay a lot of attention to statistics when I write my own scripts but if you do then Scenarist has a good range from character and word counts to how big a percentage of dialogue each character has spoken.

Scenarist Summary Statistics Page.
Scenarist Summary Statistics Page.

Within the statistics section there are useful features like the ability to isolate each character's dialogue. Which might be useful if you have a large script and just wanted to send your voice actors only their character's dialogue.

There's even a couple of interesting charts that analyze story structure and character activity.

Some of this could be handy if you're trying to give characters equal screen time or just want to know if there's enough action compared to dialogue etc. Most useful for me is the duration estimates both on the summary page and for individual scenes, in brackets next to the scene headings in the script writing section. 


The tools section allows you to restore your script to a previous backup version (by default Scenarist automatically backs up your script to a specified folder) or to compare versions. If you're the kind of writer who likes to save earlier drafts. Scenarist will let you create multiple drafts of your script from the 'Menu' button menu. I'd imagine this is where the detailed statistics would really come in handy.

Preview, Importing, and Exporting Your Script

All of this can be done from the 'Menu' button menu. Scenarist is compatible with and can import many common script writing and word processing apps including; Final Draft, Trelby, Fountain Text, and Celtx. It can also export to a few different formats including Fountain Text, and PDF.

A nice touch is being able to export your research to PDF documents too.


Scenarist can be configured for a wide range of different languages and includes other standard script templates for different regions (or make your own) that you can make the default.

The interface has light or dark versions and you can customize which panels you want showing by default.

---o ---o--- o---

As a script development tool Scenarist is really well thought out. The addition of the research and cards sections put this a step ahead of many other screen writing apps. It's a great tool for when you're starting completely from scratch.

The script that I developed for this article I wrote most of it in an afternoon (admittedly it's only three pages long). If you look at my scene cards (in the Card section above), at the time of writing this, I still have some dialogue to write between Mia and the car rental company manager.

The workflow of brainstorming a few loglines and settling on the most promising. Then writing a synopsis and expanding the synopsis into scenes and cards. Then using the cards to actually start writing your script is an excellent way to prevent 'blank page syndrome'.

It's hard to believe Scenarist is completely free and I haven't even covered all the features (such as the ability to add annotations and other features that may be useful if you're collaborating on a script).

It really is the ideal script writing tool for most screenplay writers.

Inochi2D - Free Open Source 2D VTuber Avatar Rigging and Puppeteering Software (Part 1)

Inochi2D Creator - Free Open Source VTuber Software. If you've been looking for a way to live perform as a 2D cartoon avatar on camera, whether it be for a live stream or for pre-recorded content like educational videos, then VTuber software is a low cost (or even no cost) option worth looking into. In my previous post, How to Become a VTuber - 2D and 3D Software for Creating and Controlling Your Avatar , I took a brief look at the relatively new but completely free and open source Inochi2D  which I thought showed great potential for my own needs of creating a live performance character rig for my own TET Avatar that I use for all my promotional materials. While it is possible to live perform my character using Cartoon Animator itself, Reallusion's MotionLive2D capture system isn't great - with lip sync in particular. More importantly though, I can't exactly teach people how to use Cartoon Animator if I'm using Cartoon Animator to control my Avatar. What is Inochi2D

Moho 14 Released - Still the Best 2D Animation Software for Indy Animators on a Budget

Moho 14 Released. Regular readers know I am a Reallusion, Cartoon Animator advocate through and through. Hands down I would recommend Cartoon Animator 5 first over Lost Marble's Moho 14 to anyone who is just starting in 2D animation, is a team of one, or just needs to animate as quickly as possible. However, feature for feature, Moho is, arguably, the best 2D animation software for the rest of us who can't justify a Toon Boom Harmony , or Adobe Creative Cloud subscription (and even with their applications Moho is very competitive on features). You can get started with Moho Debut for just USD$59.99 which is a cut down version of Moho Pro but it still has the most essential features needed for 2D animation. While Moho Pro is a whopping USD$399.99 (Cartoon Animator, which only has one version, is just USD$149.00) upgrades to new version numbers come down to a quarter of the price at USD$99.00. Even though Reallusion just released features like Motion Pilot Puppet Animation and

Start Your 2D Animation Side Hustle - Sell Your Cartoon Animator Characters, Props, Scenes, and Motion Files in the Reallusion 2D/3D Marketplace

Have you thought about starting a side hustle selling your original Cartoon Animator assets in the Reallusion 2D/3D Marketplace ? In this article, the first in a series on selling in the marketplace, I'll give you an overview of what's involved, why you should give it some thought, and whether you can earn enough to quit your day job (or at least have a worthwhile side hustle). If you're an artist with any kind of drawing skills, and you're creating your own original characters, props, scenes, and even motion files for your Cartoon Animator projects, then setting up your own store in the Reallusion Marketplace should be a no brainer. You're making content already, it doesn't cost you anything to set up, and Reallusion only takes a 30% commission from each item sold. (If you think that's a lot, I'll address that further down). Don't be put off if you think your art skills aren't up to professional standards. There are plenty of artists with naïve

Wonder Unit Storyboarder - Free Storyboarding Software for People Who Can (or Can't) Draw

Wonder Unit Storyboarder.  As an independent and solo animator I'm always tempted to try and skip storyboarding my animated shorts because they're usually only single scene sketch comedy type jokes. As a result I have many unfinished projects that kind of petered out due to having no clear finishing line. Storyboarding your productions, no matter how small, gives you a step by step guide of every shot that needs to be completed (no planning shots as you animate). It also allows you to create an animatic that gives you a rough preview of the finished production. In short, you shouldn't skip storyboards as they, generally, increase the chance of the project being completed. Disclaimer - I'm Not a Fan of Storyboarder Upfront, Wonder Unit's Storyboarder  is not my preferred storyboarding software. However it's completely free, has a number of very compelling featu

Can You Learn Reallusion's Cartoon Animator 5 for Free Using Their 137 Official YouTube Video Tutorials Sorted Into a Logical Learning Order?

Or you could just buy The Lazy Animator Beginner's Guide to Cartoon Animator . While Reallusion's Cartoon Animator is one of the easiest 2D animation studios to get up and running with quickly, learning it from all of the official, free, video tutorials can be more overwhelming than helpful. With more than 137 videos totaling more than 28 and a half hours of tutorials, spread across three generations of the software (Cartoon Animator 3 through 5) it's hard to know if what you're learning is a current or legacy feature that you either need to know or can be skipped. Many of the official tutorials only teach specific features of the software and don't relate at all to previous or later tutorials. As a result there are many features either not mentioned or are hard to find. To make your learning easier, on this page, I've collected together all of the essential, official, free video tutorials and sorted them into a learning order that makes sense. Simply start at

2D Animation Side Hustle - How to Find a Niche Market Selling Digital Characters, Props, and Background Art in the Reallusion 2D Marketplace

C ontinuing my series on your 2D Animation Side Hustle, Selling in the Reallusion 2D Marketplace , in this article I'm going to take a look at niches and why they're important to becoming a successful seller. I'll also look at some indicators, specific to the Reallusion Marketplace, that can help point you in the right direction of finding niches that are in demand. What is a Niche and Why Are They Important? In marketing terms a niche is kind of like a sub category or a section of a subject that you want to focus on. It's not the big idea with wide appeal that everybody loves, it's a smaller, more specific section of the idea that fewer people really connect with. For example, in the Reallusion 2D Marketplace, Characters are the biggest sellers. Everybody loves and wants to buy characters. They're great! That's all you need to know, characters sell the best, go make some! There are currently 4413 characters for sale in the marketplace. How will people find
