Frequently Asked Questions
How does this plagiarism checker work?
This tool analyzes your text for signs of non-original content by examining writing style consistency, sentence complexity variance, vocabulary shifts, tone and formality changes, and duplicated phrases. It assigns each sentence an originality likelihood and calculates an overall score.
Does this tool check against online sources?
No. This tool performs heuristic analysis entirely in your browser. It does not compare your text against any online database or external source. It detects plagiarism indicators such as inconsistent writing patterns that suggest text was copied from multiple sources.
Is my text sent to any server?
No. All processing happens client-side in your browser using JavaScript. Your text never leaves your device, making this tool completely private and secure.
What do the color highlights mean?
Green highlighted sentences appear to be original based on consistent writing patterns. Yellow sentences show some suspicious indicators such as moderate style shifts. Red sentences have strong plagiarism indicators like abrupt complexity changes or duplicated phrasing.
How accurate is the originality score?
The score is a heuristic estimate based on writing style analysis. It is useful for spotting inconsistencies that may indicate copied content, but it is not a substitute for database-backed plagiarism detection services. Use it as a first-pass screening tool.
