Source Overlap Checker
Compare a draft against reference text supplied by the user and flag exact phrase overlap for citation or quotation review. It does not search the internet, journals or institutional plagiarism databases.
Use the Plagiarism Checker
Compare a draft against reference text you supply and flag exact phrase overlap for citation/quotation review. This local tool does not search the internet or institutional databases.
Calculation, text generation and supported file processing happen locally in your browser; this batch does not require a new external processing service.
This local similarity check compares only the reference text you provide. A low result does not prove originality, and a high result does not by itself prove plagiarism; review quotation, citation and attribution in context.
How to use it
Start with the realistic worked example, replace it with your own verified values or files, inspect the result, and check the stated assumptions and limitations before using the output.
How the Source Overlap Checker works
Compare a draft against reference text you supply and flag exact phrase overlap for citation/quotation review. This local tool does not search the internet or institutional databases. The methodology documents the real Build 0216 production workflow, its verified QA fixture and the limits that prevent generated or transformed content from being represented as independently verified fact.

Worked example
Mia, a content and operations specialist, has a draft paragraph and the source text already cited in an assignment, and wants to find exact phrase overlap that may need quotation marks or closer attribution before submission.
Example inputs
- Draft text: The contractor will maintain the temporary bypass pump until the permanent pump is commissioned. Daily inspections will record flow vibration and seal condition.
- Reference/source text to compare: The contractor will maintain the temporary bypass pump until the permanent pump is commissioned. The operations manual separately requires daily checks.
- Exact phrase length (words): 5

Use the verified QA fixture: Draft text: The contractor will maintain the temporary bypass pump until the permanent pump is commissioned. Daily inspections will record flow vibration and seal condition.; Reference/source text to compare: The contractor will maintain the temporary bypass pump until the permanent pump is commissioned. The operations manual separately requires daily checks.; Exact phrase length (words): 5.Apply the production assemble or transform the requested content from explicit user inputs workflow exactly as described on this page.The production QA fixture reports: Local source-overlap check: 52.6% - 10/19 5-word phrases matched.
The result is the verified Build 0216 output for this exact scenario. It should be interpreted with the displayed inputs, assumptions and limitations rather than as context-free advice.
Assumptions
- The user has the right to use the supplied source material and provides the factual context required by the tool.
- Generated or transformed text is based on the explicit inputs and documented local/template rules; hidden factual verification is not assumed.
Limitations
- Generated text can be incomplete, awkward or unsuitable for a specific audience and must be reviewed by the user.
- For plagiarism, grammar, translation, career, academic, legal or professional use, this utility cannot guarantee originality, acceptance, semantic equivalence or compliance beyond its documented checks.

What should I verify before relying on the output?
Check the entered values, stated assumptions, support boundaries and any authoritative sources linked on the page; independently review high-stakes use.

A realistic way Mia could use this tool
Mia is a content and operations specialist.
Mia has a draft paragraph and the source text already cited in an assignment, and wants to find exact phrase overlap that may need quotation marks or closer attribution before submission.
Mia compares a 23-word draft about maintaining a temporary bypass pump with the supplied reference passage and chooses a 5-word phrase size. The checker creates rolling 5-word phrases locally and compares the draft phrases only against that supplied source text.
The test finds 10 matching phrases out of 19 draft phrases, or 52.6% exact 5-word overlap. Mia gets the matched phrases to review, while the page makes clear that it has not searched the web, journals or an institutional plagiarism database.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
