A simile draws a vivid comparison between two unlike things using like or as — as quiet as a held breath, she moved like a leaf caught in a current. The explicit comparison word is what sets a simile apart from a metaphor, which equates the two things outright. This free tool builds similes in two classic grammatical patterns so you have an instant source of comparisons for poetry, fiction, scripts, and lessons on figurative language.
How it works
The generator keeps a bank of descriptive qualities (each paired with several surprising comparators) and a separate set of subject/verb openers with like-comparators. Depending on the pattern you choose:
- as X as Y picks a quality such as cold and a matching comparator such as a banker’s smile, producing
as cold as a banker's smile. - subject verb like a… picks an opener such as She moved and a comparator such as like a leaf caught in a current.
Both patterns are assembled entirely in your browser with no network request.
The two patterns side by side
| Pattern | Example |
|---|---|
| as [quality] as [comparator] | as patient as old stone |
| as [quality] as [comparator] | as sudden as a door slammed in wind |
| [subject] [verb] like [comparator] | She spoke like a judge reading a verdict |
| [subject] [verb] like [comparator] | The city breathed like something alive |
What makes a simile land
The best similes do not just say something is like something else — they carry a secondary meaning. As cold as a banker’s smile describes temperature but also implies calculation and indifference. When reading generated results, ask whether the comparator adds a second layer of meaning or just describes the quality more vividly. Keep the ones that do both.
Avoid the obvious end of the spectrum. Comparisons like as fast as lightning or as cold as ice have been worn smooth by overuse. The tool deliberately weights away from these, but you may still want to reroll if the result feels too familiar.
Adapt, don’t just transplant. A generated simile is a starting structure. If the comparison almost works but the noun is wrong for your character’s voice, change it. As quiet as a held breath could become as quiet as the second before a question — same bones, more specific.
When to use this tool
Creative writing teachers use it to produce classroom examples of figurative language quickly, especially when they need a pair of fresh comparisons for a lesson on the as-X-as-Y form. Novelists use it as a warm-up exercise — generate ten, pick the best two, and the writing session starts with momentum. Poets use it when a line needs motion or texture but the right image is not coming.
