Plagiarism Checker
Splits your text into sentences and generates exact-match Google searches — no database, fully private.
No database — honest originality helper
This tool does notcompare your text against any external source. It generates one Google search link per sentence so you can manually verify each one. The “uniqueness” percentage only reflects duplicate sentences within this document — it is not an authoritative plagiarism score.
Check text originality with Google searches
Paste any text and this tool splits it into individual sentences, then generates an exact-match Google search link for each one. Click any “Google” link to open a new tab and see whether that sentence appears verbatim on other websites.
The internal uniqueness percentage counts how many sentences are unique within your text. Repeated sentences lower the score. This is useful for spotting accidental repetition, but it is not a comparison against external sources — use the Google links for that. Your text is never sent to any server.

What this tool is used for
- Generating exact-match searches per sentence to check a passage's originality.
- Checking a submitted piece for text lifted verbatim.
- Verifying your own draft has not accidentally reproduced a source.
- Checking a quotation is attributed rather than absorbed.
- Auditing a page for content copied from elsewhere.
Frequently Asked Questions
- Does this compare my text against a database?
- No, and that is the honest limitation. It splits the text into sentences and builds a search link for each so you can check them yourself. A real plagiarism service maintains a licensed corpus of publications and student papers, which no client-side tool can have.
- Why search sentence by sentence?
- Because a quoted-phrase search on a distinctive sentence is the single most effective manual check there is. A whole paragraph rarely matches exactly, while one unusual sentence either returns the source immediately or returns nothing.
- What counts as plagiarism?
- Presenting someone else's words or ideas as your own — which includes paraphrasing without attribution, not only copying. That is why a clean search result is not proof of originality: reworded material is invisible to an exact-match search and is still plagiarism.
- Can it detect AI-generated text?
- No — that is a different question and a much less reliable one. Detectors for it produce both false positives and false negatives at rates that make them unsafe for consequential decisions, which several universities have concluded publicly.
- Is my text sent anywhere?
- Only when you click one of the generated search links, and then only that one sentence goes to the search engine. Nothing is uploaded in bulk, which matters if the document is unpublished — submitting a draft to a checking service means handing over a copy of it.
Common errors and gotchas
- Treating an exact-match search as proof, since paraphrase and translation both defeat it.
- Assuming no results means original, when the source may not be indexed.
- Reading a match as plagiarism when it is a correctly attributed quotation.
- Searching sentences so short that any match is coincidental.
- Using the result as an accusation rather than as a prompt to look properly.
