Paraphrase Distance Checker

Compare a source passage with a paraphrase and measure surface-level distance in wording and phrase order. The checker reports shared words, matching sequences, vocabulary overlap, and a sentence-level risk signal while ignoring common function words when requested. It can reveal patchwriting patterns, but only the writer can verify faithful meaning and provide the required citation.

What this tool does

The source and paraphrase are separated at the labeled divider, tokenized case-insensitively, optionally stripped of common function words, and compared with Jaccard overlap plus contiguous n-grams.

The source and paraphrase are separated at the labeled divider, tokenized case-insensitively, optionally stripped of common function words, and compared with Jaccard overlap plus contiguous n-grams.

Low wording overlap does not prove an accurate or ethical paraphrase. Preserve the source meaning, cite the source, and quote any distinctive wording that must remain exact.

Example

Sample input:

Processing details

Paste the source first, then a line containing --- PARAPHRASE ---, then the paraphrase. Punctuation and capitalization do not affect token matching.

This is not a plagiarism detector. It has no source database and cannot judge semantic accuracy, common terminology, citation completeness, or translated paraphrases.

Frequently asked questions

How different should a paraphrase be from the source?

The tool reports surface-level evidence related to paraphrase distance checker. Review the result in the context of your assignment, audience, and source material.

What is patchwriting in academic writing?

Use the finding as a revision prompt rather than an automatic verdict. Requirements and preferences can differ by discipline, publication, and individual context.

Does low word overlap mean my paraphrase is acceptable?

The analysis runs entirely in your browser and returns a transparent report. It does not contact external databases or certify correctness.

Why does the checker ignore common function words?

Yes. Edit the input, adjust the available option, and run the check again to compare how a specific revision changes the report.

Can this tool replace plagiarism detection software?

No. The tool cannot replace a subject expert, accessibility review, instructor, editor, or verified style guide; it is designed for focused first-pass review.
