What you get
You: a cautious accountant who gets pulled into a casino heist.
1 · Inciting incident first
When a casino heist crew mistakes him for their inside man, a timid accountant must fake his way through the job or lose the life he carefully built.
2 · Irony first
A man who has never broken a rule must rob the very vault he audits, but the crew he is helping trusts him less every hour.
3 · Tight cut
A timid accountant mistaken for a heist crew's inside man must bluff his way through the job, or lose everything.
My pick: 1. It starts the story with a clear mistake and a clear cost.

How to write a logline
A logline is one sentence that sells your film. It names a hero, the thing that disrupts their life, what they must do, who or what opposes them, and what happens if they fail.
The most reliable formula is: When [inciting incident], a [flawed hero] must [goal] against [opposing force], or [stakes]. Both the skill and the quick form fill it in three ways so you can see which version feels strongest.
Keep it to one sentence, leave out names, and describe the setup rather than the ending. The best loglines also carry a little irony: a hitman who wants to be a better father, a cautious accountant stuck in a heist.
Once your logline works, it becomes the spine for the rest of your script. Our screenplay guide shows where it fits, and the character development guide will help you sharpen the hero.
Logline FAQ
What is a logline?
A logline is a one or two sentence summary of a film that names the protagonist, what they want, what stands in their way and what is at stake. It is the pitch you can say in one breath.
How long should a logline be?
Aim for one sentence of roughly 25 to 50 words. Anything longer starts to read like a synopsis.
Should a logline include character names?
Usually not. Use a role and a defining trait, like "a disgraced ex-detective", so the reader pictures the character without remembering a name.
What makes a good logline?
A relatable protagonist, a clear goal, a strong opposing force, real stakes and a hint of irony or a fresh angle. It should describe the premise, not give away the ending.
Which AI tools does the logline skill work with?
Claude (as an installable skill), Cursor (as a rule file), and ChatGPT, Grok, Gemini or any other AI chat through the copy-and-paste prompt. It is the same set of instructions in each format.
Is the logline generator free?
Yes. The skill, the prompt and the quick form are all free. You only need an account with whichever AI tool you choose, and its usual plan limits apply.
Does the skill store my story?
No. Filmmaking Central never sees your story. The skill runs inside your own AI tool, so your privacy depends on that tool's settings. The quick form runs in your browser and sends nothing anywhere.
Is the quick form AI?
No. The form uses proven logline formulas to assemble your own answers into three structures. Use it if you do not want to download anything or use AI.
