Film Logline Idea Generator
A film logline idea generator produces the hardest sentence in screenwriting: the one-line pitch that sells a movie by assembling a protagonist, a goal, an obstacle, and a hook of irony in your chosen genre. Pick Thriller, Drama, Sci-Fi, Comedy, or Horror and it returns a logline that implies the whole film — its stakes, emotional core, and central irony — in a single breath. The single input is genre, which sets the tonal register and the kind of stakes involved. Each logline is built so a producer reading it can picture the film without being told what happens on page 90. Results are unique and regenerate every run. Workflow tip: use the logline as a filter for every script decision. If a scene, character, or subplot does not serve the logline's promise, cut it. A strong logline is not just a pitch tool — it is the compass that keeps a hundred pages focused.

FAQ
what makes a strong logline
It names a protagonist, a clear goal, and a real obstacle, and implies the stakes — all in one sentence that makes a reader want to know what happens. The best loglines also carry a hook of irony that hints at the film's deeper conflict.
why practise writing loglines
The logline is the hardest and most useful sentence in screenwriting. If you can sell the whole film in a line, you understand its core; if you cannot, the story may not be focused yet. It is also what gets a script read.
how do i develop the logline
Tighten it to one clean sentence, then expand outward: who is the protagonist really, what is the world, and what ending does this conflict earn. The logline is the seed; the script is the execution.
how long should a logline actually be
One sentence — ideally under 35 words. That discipline forces you to identify what the film is actually about: who wants what, what stops them, and why the situation is ironic. If you need two sentences, the concept likely needs more focus before it is ready to pitch.
what's the difference between a logline and a synopsis
A logline is a one-sentence hook designed to make someone want to read the script — it names the protagonist, goal, and obstacle without revealing the ending. A synopsis is a full story summary that covers the entire plot. In a pitch meeting you lead with the logline; the synopsis only comes if they ask for more.
