Jasper AI logline

Artificial Intelligence (AI) has already disrupted many industries, and screenwriting and novel writing are no exceptions.

AI content generators are now being used to help writers create compelling loglines for their movies and books.

As a novelist, screenwriter, and filmmaker myself, I know how hard writing can be. I’ve been trying out different AI writing programs to see how they can be best used for creatives, and one use that stood out to me was the writing of loglines.

In this article, we will discuss how to use artificial intelligence writing programs (like ChatGPT or Jasper AI) to help you write a creative logline for your next creative project!

What Are AI Writing Programs?

AI writing programs can be an excellent tool for fiction writers.

There are many different kinds of AI writing software programs available, from grammar-checking programs (such as Grammarly) to AI writing assistants (such as Quillbot) to writing tone assistants (such as ProWritingAid), all the way to more creative AI story generators (such as Jasper).

Using artificial intelligence, these story generator programs can help you generate ideas, develop new plots, and even create characters, settings, and dialogue.

Of course, they can also help you organize your thoughts and get a better sense of your story’s direction.

AI writing programs can be valuable for any fiction (or non-fiction) writer.

What is a Logline for a Movie or Book?

A logline is a brief summary of a movie, short film, or book that tells the reader the plot and the central conflict.

It’s usually one or two sentences long, and it’s a great way to get a quick sense of what a story is about. It should be easy to understand and make the reader want to know more about the story.

Writers often use a logline to pitch their ideas to publishers or producers. It is also a valuable tool for marketing and advertising purposes.

In short, a logline is a concise way to summarize a complex story in just a few words.

How do I Write a Compelling Logline?

Overall, my best tips for writing a logline are:

  • Keep your logline short and to the point
  • Brainstorm your best movie ideas before you write the logline!
  • Think about the key ingredients of the story elements of your book or movie before writing the logline
  • Focus on the main conflict in your story (the central problem that moves the plot forward)
  • Don’t use character names in your logline
  • Don’t give away the entire script or the whole movie!
  • Avoid naming similar books or movies in the logline

Keep the following logline formula in mind as you use Jasper AI to help you write a logline:

How to Use AI Writing Programs to Create a Well-Written Logline: 5 Steps

Now that you know what a logline is and what an AI writing assistant can do let’s look at how AI can help you write a compelling logline.

Before we start, please note that I’m using the word “help”!

Artificial intelligence is a beneficial tool but does not replace the human writer. You will still need to understand story structure, character development, and the idea of conflict to write a great logline.

With that said, let’s look at how to use AI to help you quickly and easily write a movie or book logline!

Step 1: Decide on the parameters of your logline

The first step to creating a logline for a story is to decide on the parameters of your story.

A good logline distills the essential story elements of your screenplay – protagonist(s), antagonistic forceinciting incident, and objective – into a clear and concise teaser.

Reread your story or screenplay and make sure that you can specify the following aspects:

  • Protagonist(s) – The story’s main character(s).
  • Inciting Incident – The event that sets the protagonist(s) on their journey. This is the first turning point, where the main character’s ordinary world upends.
  • Objective – The main goal of the protagonist(s).
  • Antagonistic force – The character, force, or obstacle preventing the protagonist(s) from reaching the objective.

Try to add as much detail as possible about each aspect of your story.

Once you have written down these aspects of your story, you can start writing your logline!

Let’s look at an example from a famous movie (The Wizard of Oz):

  • Protagonist: lonely Kansas farm girl
  • Inciting Incident: a twister takes her to a magical land
  • Objective: find a wizard who has the power to send her home
  • Antagonistic Force: a dangerous journey

Step 2: Open a new document in your AI writing program

This step is where you’ll need to sign up for an AI writing program. While I’ve tried quite a few, the two I recommend to fiction writers most are Jasper and Rytr. However, for the purpose of writing a logline, I recommend Jasper!

Jasper is my favorite AI writing tool overall, and if you try it out through my affiliate link (below), you’ll get a five-day free trial of the software and 10,000 free credits to try it out!

If you are using Jasper AI:


In Jasper, you’ll want to click on Templates, Documents, and “Freeform With Any Template.”

Step 3: Use this prompt to generate your logline

In your opened document, copy and paste the following prompt. Make sure to type in your own parameters where it says, “state yours here.”

<write a logline for the following parameters: main character – state yours here, inciting incident – state yours here, objective – state yours here, antagonistic force – state yours here>

After you enter your own parameters, put your cursor after the final > and press “control J.”

Here’s what happened when I used this prompt in Jasper (the part in the red box was what I gave as a prompt, and the logline below was what Jasper generated for me):

Now, this logline that Jasper generated is not great. So, let’s go on to step 4!

Step 4: Try rerunning the AI program if you are not happy with your AI logline

Artificial Intelligence is far from perfect. You may need to adjust your parameters if the logline you get is not quite what you are looking for.

For example, you may need to add extra information about your protagonist (it may give a better logline if you say a “young cocky hockey player from Norway” than just a “hockey player”).

Or, you may need to rerun the AI program. It will often give slightly different loglines each time that you run the command, and you will likely prefer one option to the others.

When I re-ran the Jasper command, I liked the third logline the best (the one right under the red box)!

Step 5: Tweak the logline to make it your own!

Remember that AI is just an assistant to you, the human writer! Please ensure that you use your creative talents and skills to make the logline the best it can be.

Ensure that you add details or adjust the meaning of the logline so that it is true to the story you are writing it for.

I believe that this logline generation method can help make the process easier and faster, but you should not let AI do all the work for you!

In the end, I moved the elements around a bit and went with this logline:

After a twister carries her to a magical land, a lonely Kansas farm girl embarks on a dangerous journey to find a wizard with the power to send her home.

Using ChatGPT to Write a Logline

Here’s the output I got when I asked ChatGPT to write me an AI logline for the Wizard of Oz. It’s pretty good, but would benefit from some human tweaking!

chatGPT logline

The nice thing about ChatGPT is that you can ask the program to rewrite the logline in different ways.

Look what happens when I ask the program to rewrite the above logline with the prompt “write this more powerfully”. It is a fantastic logline!
