How is similarity calculated?

Using Jaccard similarity on unique word sets: shared words divided by total unique words across both documents, expressed as a percentage.

What are shared phrases?

Two-word sequences (bigrams) that appear in both documents. They indicate structural or content overlap beyond individual word matching.

Is this a plagiarism detector?

It measures content overlap, which is one indicator of plagiarism. However, it does not check against external sources -- only the two documents you provide.

Does it understand Markdown syntax?

Yes. Markdown formatting and code blocks are stripped before comparison, so only prose content is measured.

No. Both documents are processed entirely in your browser. Neither is ever sent to a server.
