Joke Originality Checker
Paste a joke to find the most similar jokes in the database.
How it works
Paste your joke.
A bit, a line, or a full chunk of material — up to 2,000 characters.
We compare it line by line.
Your text is matched against every joke in the database using semantic similarity, not just word overlap.
See the closest matches.
The top matches show the full joke with line-level highlights, linked straight to the set and timestamp.
FAQ
How do I check if my joke has already been done?
Paste your joke into the checker above. It searches a database of annotated stand-up jokes using semantic similarity — matching ideas and phrasing, not just exact words — and shows the closest matches with line-by-line highlights.
What does the similarity percentage mean?
It measures how close the meaning of your text is to a joke in the database. A high score means the ideas and structure closely overlap. It is a measure of similarity, not proof that either joke was copied.
Does a high match mean a joke was stolen?
Not necessarily. Comedians independently arrive at similar ideas all the time — this is known as parallel thinking. A high match is a signal worth reviewing, not an accusation of joke theft. Click through to the original set and judge the context yourself.
What jokes does it check against?
A growing database of stand-up material annotated joke by joke, with each line labelled as setup, punchline, or tag. Coverage is expanding all the time.
