The Logline Formula

Screenwriters and novelists use loglines to test whether a story has an engine before they write it. A strong logline answers five questions: who is the hero, what starts the story, what do they want, what happens if they fail in time, and what stands in the way. Every idea here follows that structure:

When [inciting incident], [protagonist] must [goal] before [deadline], but [obstacle].

Worked example: "When a guest vanishes from a snowbound inn, a hotel concierge must find the real culprit before the storm clears and the suspects leave, but every suspect has an alibi." In one sentence you know the hero, the mystery, the ticking clock and the central problem.

How Many Ideas Are There?

Each genre has 8 protagonists, 8 incidents, 8 goals, 8 deadlines and 8 obstacles, written to fit together. That gives 85 = 32,768 loglines per genre, or 262,144 across all eight genres. Adding one of 6 settings, 14 themes and 6 formats raises the total to 132,120,576 full concepts. Parts are picked with your browser's secure random source, and a batch never repeats an idea.

How to Develop a Story Idea

  • Ask why. Why is this hero the one who must act? The answer usually becomes the character's backstory.
  • Raise the stakes. Decide what the hero loses if the deadline passes, both in the world and personally.
  • Connect the theme. Let the theme shape the ending. A story about forgiveness should end with someone forgiving, or failing to.
  • Swap freely. Keep the parts that excite you and replace the rest. A mystery logline can become a comedy with a new obstacle.
  • Outline three turning points: the incident, a midpoint surprise and a final choice. That is enough to start drafting.

Picking a Format

The suggested format is a nudge, not a rule. A short story suits a single, sharp twist and a few scenes. A novella has room for one main plot and a subplot. A novel can follow several characters. A screenplay depends on visual action and dialogue, and a graphic novel or web serial rewards strong images and cliffhangers.

What Each Genre Brings

The parts in each genre are written to fit that genre's promise to the reader. Fantasy ideas lean on curses, prophecies and invented places. Science fiction ideas follow one technology or discovery to its consequences. Mystery ideas always hide a culprit and give the hero a reason to investigate, while romance ideas put two people in each other's way and give them a reason to stay apart.

Horror ideas build dread around a place or a presence, adventure ideas send the hero somewhere dangerous with a clear prize, comedy ideas start from an embarrassing mistake that keeps snowballing, and drama ideas focus on family, work and the choices that change a life. Mixing genres is a classic way to find something fresh: try keeping a mystery hero and swapping in a horror obstacle.

Which genres can I choose?

Fantasy, science fiction, mystery, romance, horror, adventure, comedy and drama. Choose Any genre to mix them, and each idea is labeled with the genre it came from.

Can I use these story ideas for a book or film?

A prompt gives a starting situation. A logline gives a whole story engine: the goal, the deadline and the obstacle, which tell you where the story is going and how it might end.
