Opening Line Generator

Generate a random opening line — a starting sentence to build a scene or story around.

What this generator does

Builds a first sentence for a piece of fiction, combining sentence patterns with slot banks so the output is a usable line rather than a topic to write about.

What it builds, and how many ways

Each result is assembled to this shape: [subject] + [action] — one of 5 sentence patterns this generator uses.

  • action: 20 options
  • subject: 20 options
  • surprise: 18 options

Taken together those banks can be assembled 1,880 different ways, repeating after about 54.

Some results it can produce:

  • she hadn't meant to sign the form, but by then it was too late.
  • The last thing the new tenant expected was the train never stopped at that station.
  • Nobody warned my sister that the mirror showed yesterday.
  • the man who owned the field would remember it as the day the field had been ploughed overnight.

A fixed sample so this page stays the same between visits. Your own results are assembled at random, each slot filled independently and each press independent of the last, so the same result can come up twice — past the repeat figure above, seeing one twice is more likely than not.

How to use this tool

  1. Press generate for a new opening line.
  2. Generate again any time for a new one.

Common use cases

  • Overcoming a blank page
  • Classroom writing warm-ups
  • Flash-fiction exercises

How this generator works

An opening sentence is assembled from a situation, a voice and a turn — the three things an opening line has to do at once. Assembling rather than drawing whole lines is deliberate: a stored opening line is somebody else's, while a combination of ingredients is a prompt the writer still has to finish.

Limitations and good to know

  • A line to react to, not a line to keep. Most writers find its value is in provoking a better first sentence of their own.
  • A prompt, not a sentence to publish. The value is in what it makes you write next.
  • The parts are drawn independently, so a combination can be tonally incoherent — which is often the more interesting prompt.
  • Nothing checks the result against published work, and a short common phrase can coincide with one.

Each part of the result is chosen independently with your browser's cryptographic random number generator, so every option in a bank is equally likely. How Generate Random works.
