Two drafts can look different and still share the same sentences. Plagiarisma’s free text comparison uses AI to line up two passages and highlight similar wording, changed phrases, and sections that do not match. Paste both texts or upload documents and review the overlap before you submit, edit, or merge a revision. It is a side-by-side check for students, editors, and writers — not a verdict that one text copied the other.

How to Read a Text Comparison Without Overreading It

An AI comparison shows where two texts sit close. Shared topic words and standard phrases can match even when neither text copied the other. Use the highlights as a map, then read the passages.

1. Separate exact overlap from similar meaning

A copied sentence is not the same as two texts describing the same fact. Look at the marked spans before you decide.

• Treat long identical stretches as the first places to rewrite or cite.

• Do not treat a shared keyword as proof of copying.

• Open both passages and read the sentences around the highlight.

2. Use it on a revision, not only on a suspicion

Comparing your new draft with the previous one shows what changed and what you left in place. That is useful before a final edit.

• Check that a paraphrase actually moved away from the source wording.

• Confirm that a deleted claim did not survive in another paragraph.

• Keep the version you mean to submit.

3. Cite when the overlap is a source

If one text is an article or a book passage, similar wording still needs a citation. Comparison does not replace a reference.

4. Pair the result with a plagiarism check when the text will be submitted

A two-text comparison only sees the files you gave it. For a paper, run the plagiarism checker as well so web sources are in the picture.

The goal is a clear view of what the two texts share, not a score that stands in for reading them.
