Fill in the protagonist, goal, and obstacle, then generate three logline variations built from proven structures.

A logline is a one- or two-sentence summary of your story: who the protagonist is, what they want, and what stands in their way. It's the first thing an agent, a producer, or an AI co-writer needs to understand your idea — and the sharpest tool for finding out if your concept actually has a spine.

Craft notes

What makes a logline work

Be specific, not vague

“A man tries to save his family” is generic. “A bankrupt accountant must launder money for the cartel that killed his partner, or lose his own family next” is specific — it names a role, a concrete goal, and a concrete threat.

Name the irony

The strongest loglines often contain a built-in contradiction — a peace-loving soldier, a claustrophobic astronaut. That tension is what makes a concept feel like a movie instead of a situation.

Skip the theme, keep the plot

A logline isn't the place to explain what your story is “about.” It's the place to explain what happens. Theme reveals itself once someone reads the script.

Cut adjectives, keep verbs

Loglines weaken under adjectives (“a brave, determined detective”) and strengthen under action (“a detective who frames her own partner”). Let what the character does show who they are.

FAQ

Logline generator, answered

What makes a good logline?
A strong logline names a protagonist, states a clear goal, and introduces the obstacle standing in the way — usually in one or two sentences. The best ones also imply stakes: what happens if the protagonist fails.
How long should a logline be?
One to two sentences, typically 25–50 words. If you need a paragraph to explain it, the concept usually needs to be sharpened, not the sentence lengthened.
Is this logline generator powered by AI?
No — it's a free, template-based tool that assembles your protagonist, goal, and obstacle into proven logline structures instantly, with no signup or AI credits required. For AI-assisted writing of full scenes from an idea, see the SceneCraft AI Script Generator.
Can I use the generated logline for free?
Yes. Loglines you generate here are yours to use however you like — in a pitch, a query letter, or as the seed for a full screenplay.
