Logline Generator
A logline generator creates a compelling one-to-two sentence story summary that captures your protagonist, their goal, the central conflict, and the stakes. Enter your story details in the panel and get a Hollywood-ready logline in seconds — no signup required.
What Is a Logline?
A logline is a one-sentence story summary used by screenwriters, novelists, and filmmakers to pitch their project to studios, agents, and producers. It is the Hollywood standard for capturing the essence of a story in under 50 words. A strong logline answers four questions at once: Who is the protagonist? What do they want? What stands in their way? What are the stakes if they fail?
Loglines are used in query letters, pitch decks, festival submissions, and development meetings. They are the first impression a story makes on any industry professional. If your logline does not hook someone immediately, your script rarely gets a second look. Need help writing the script itself? Try our Free AI Script Generator after you lock in your logline.
How the Logline Generator Works
Describe Your Story Concept
Enter a brief description of your story idea in the Story Concept field. Include the setting, situation, and what makes your story unique. The more specific you are, the more targeted your logline will be. Avoid generic descriptions — specificity is what separates a forgettable pitch from a compelling one.
Define Character and Conflict
The Main Character field asks for a brief description of your protagonist — their role, background, or defining characteristic. The Central Conflict field is optional but adds precision. Providing both gives the AI enough to craft a logline that reflects your actual story rather than a generic version of the genre. You can also use the generated logline as inspiration for your AI Character Description.
Get Polished Loglines
Choose 1, 3, or 5 logline variations. Multiple variations give you options with different angles, emphasis, or emotional hooks so you can select the one that resonates most with your vision. Each version follows the Hollywood-standard logline formula while exploring a different approach to framing the same story.
Logline Formula
Classic Logline Structure:
When [inciting incident], a [protagonist] must [objective] before [stakes/antagonist force].
This formula is the foundation of every effective logline. The inciting incident sets the story in motion. The protagonist is defined by their relationship to the problem. The objective is the clear goal they pursue. The stakes create urgency and emotional investment. Breaking any of these elements weakens the pitch.

Tips for Writing Effective Loglines
Keep It Under 30 Words
The best loglines are under 30 words. Every word must earn its place. If you need two sentences, make each one count. Cut adjectives, adverbs, and backstory. Industry readers skim hundreds of loglines — yours must land in the first read or it will not get a second one.
Include Irony or Conflict
The most memorable loglines contain an element of irony — a character forced into a situation that contradicts who they are, or two opposing forces that create unavoidable tension. Irony signals to producers that your story has built-in conflict and does not require manufactured drama. It is the difference between "a detective solves a murder" and "a detective must solve the murder of the only man who can clear his name."
Make the Stakes Clear
Stakes are what the protagonist loses if they fail. Without clear stakes, the audience has no reason to care. Stakes can be physical (life or death), emotional (love, identity, family), or societal (freedom, justice, survival of a community). The higher and more specific the stakes, the more compelling the logline. Once your logline is locked, use our Free AI Story Generator to expand it into a full narrative.
