Writing
Story Logline Generator
A story logline generator gives you one-sentence summaries that capture the heart of a story. A logline distils a whole narrative into a single sentence — protagonist, goal, and obstacle — and it is the tool writers use to test whether an idea has a strong spine before committing to writing it. This tool randomly assembles a character type, a mission, and a complicating condition into ready-made loglines. Choose how many you want (up to 8) and use the strongest as a starting point. All generated loglines share the same opening clause — "When disaster strikes, [character] must [do X] [under condition Y]" — so treat them as structural templates, not finished copy. If the output sounds flat, it is a signal the premise needs sharpening. Substitute your own specific character, goal, and complication to make it truly yours.

FAQ
What exactly does this generator produce?
Each output is a one-sentence logline built from three randomised components: a character type (e.g. "a reluctant heir"), a mission (e.g. "must expose a powerful enemy"), and a condition (e.g. "even if it costs everything"). All outputs use the same opening clause, so they are templates to adapt rather than finished loglines.
What makes a strong logline?
A strong logline names a specific protagonist, states a concrete goal, identifies the central obstacle, and implies the stakes — all in one sentence. Vague terms like "disaster" or generic characters are placeholders; replace them with the specific people and events from your actual story.
Why write a logline before drafting a story?
A logline tests whether an idea has a clear, compelling spine. If you cannot state protagonist, goal, and conflict in one sentence, the premise may be too diffuse to sustain a full narrative. Writing the logline first often reveals structural weaknesses before you have invested thousands of words.
Who uses loglines beyond screenwriters?
Novelists use them to test premises and pitch to agents. Game writers use them to anchor branching narratives. Short-story writers use them to focus a piece before drafting. Anywhere a story needs to be pitched or planned, a sharp logline is the most efficient tool for checking the idea holds together.
