Check a single piece of text online free - no signup. Flags about 10 common clichéd phrases and measures word repetition within your own text. This does not check against the web or any database, and cannot detect real plagiarism.

This tool is a quick, superficial self-check for a small set of clichéd filler phrases and for how repetitive your own word choice is - useful as a very first pass, not as plagiarism detection. Since it never compares your text to anything outside itself, it cannot tell you whether your writing matches another source.
For genuine plagiarism or originality checking, use a dedicated plagiarism-detection service that scans against a real database.
Paste your text and this tool checks it for two things: whether it contains any of a small, fixed list of about 10 common clichéd phrases (like "in conclusion" or "it is important to note"), and how much of its own vocabulary repeats within itself. It does not check your text against the web, any database, or another document, and it cannot detect real plagiarism - for that, use a dedicated plagiarism-detection service.
Enter a single piece of text - there's no second text field to compare against.

Best For
Input
A 200-word text containing 1 of the 10 fixed cliché phrases, with a 30% word-repetition rateResult
Score = 100 - (1 × 15) - (30 × 0.5) = 70% ("Moderate")The score is 100 minus 15 points per cliché phrase found, minus half the word-repetition percentage - it's an arbitrary formula based only on these two internal checks, not a measure of whether your text matches any other source.
Input
A short text that repeats the same few words often (e.g., a list of similar short sentences), containing none of the 10 fixed phrasesResult
A low-to-moderate "Originality Score," despite being 100% original writingBecause the score penalizes word repetition regardless of whether the text is copied from anywhere, genuinely original but repetitive writing (like simple, short sentences) can score lower than more varied but equally original writing.
Input
Text copied verbatim from another source, but with varied vocabulary and no matches to the 10 fixed phrasesResult
A high "Originality Score"Since the tool never compares your text to any external source, directly copied text scores exactly the same as original writing, as long as it avoids the 10 fixed phrases and has low internal word repetition - this tool cannot detect actual plagiarism.
Quickly see if your text contains filler phrases like "in conclusion" or "due to the fact" from the tool's fixed 10-phrase list.
See what percentage of your text's words are repeats of other words in the same piece.
Use the result as a small editing signal, not as evidence of originality or plagiarism.
Problem
Solution
The score only reflects two internal checks (a 10-phrase cliché list and self-repetition) - it never compares your text to the web, a database, or any other document, so it cannot detect actual plagiarism.
Problem
Solution
A high score here only means your text avoided 10 specific phrases and doesn't repeat its own words much - it says nothing about whether the content matches another source. Use a dedicated plagiarism-detection service for that.
Problem
Solution
There's only one text input field - this tool doesn't compare your text against a second document or any other source.
Problem
Solution
None exist - the result is for on-screen review only.
This tool cannot compare your text to the web or any database - it only checks your text against itself.
It's a simple formula based on cliché-phrase count and word repetition, not a similarity-to-other-sources measurement.
Short or repetitive-by-design text (lists, simple instructions) will naturally show higher word-repetition rates, lowering the score for reasons unrelated to originality.
There's no copy, download, or export button - select and copy the on-screen text yourself if needed.
The tool never compares your text to the web, a database, or another document - directly copied text and 100% original text can both score identically.
The "common phrases" check looks for exactly ten hardcoded clichés (like "in conclusion" or "once upon a time") - not a database or search of any kind.
It's calculated as 100 minus 15 points per matched phrase minus half the word-repetition percentage - a self-referential number, not a similarity-to-source score.
There's only one text field - this tool cannot compare two pieces of writing against each other.
The result is displayed on-screen only, with no way to save or export it from the tool itself.
The 1.5-second wait doesn't reflect real processing time - the underlying check runs instantly; the delay is a fixed timer.
This tool doesn't detect AI-generated text - only the fixed phrase list and word-repetition rate.
The 10 hardcoded phrases are English-only; the word-repetition check works on any language's word-splitting but has no cliché-phrase data for non-English text.
Both produce a score, but only one actually compares your text to other sources.

Visitors most often expect this tool to check their text against the web or an academic database, the way a real plagiarism checker does - it doesn't. This tool only checks your text against itself: a small fixed list of clichéd phrases, and how often your own words repeat. The FAQ below explains exactly what the "Originality Score" measures, and what it doesn't.
No. This tool only checks your text against itself - a fixed list of about 10 common clichéd phrases, and how much your own text's vocabulary repeats. There's no web search, no database, and no comparison to any other document.
It's calculated as 100 minus 15 points for each of the 10 fixed cliché phrases found in your text, minus half your text's word-repetition percentage. It does not measure whether your text matches any other source - a fully original piece of writing and a directly copied piece of writing can score identically, since neither is ever compared to anything outside itself.
No. Detecting plagiarism requires comparing your text against other documents or a database, and this tool never does that - it only analyzes the text you paste against itself. Use a dedicated plagiarism-detection service if you need to check whether your text matches another source.
No. There's only one text field - you paste a single piece of text, and the tool analyzes that text alone. It doesn't accept or compare a second document.
No. There's no copy, download, print, or export feature - the result is for on-screen review only.
It's a fixed 1.5-second simulated delay, not real processing time - the underlying check itself runs instantly.
Plagiarism includes: copying text directly without quotation marks and citation, paraphrasing another person's ideas without attribution, presenting someone else's argument or finding as your own, reusing your own previously submitted work without disclosure (self-plagiarism, in academic contexts), and using AI-generated text without disclosure where such disclosure is required. The common thread: claiming credit for work that originated elsewhere. This tool doesn't detect any of the above - see the FAQs above for what it actually checks.
This is general guidance for real plagiarism-checker reports (like Turnitin), not this tool's own Originality Score, which is a different, unrelated calculation (see above) - there is no universal standard for real similarity reports either. Most universities set thresholds of 10–25% overall similarity (excluding properly cited quotes and references sections). A 15% score that is all properly cited quotations is fine; a 5% score from an uncited paragraph is plagiarism regardless of the total. Check your institution's specific plagiarism policy for the threshold that applies to your submission.
