Frequently Asked Questions
- How does the plagiarism checker work?

- Is there a word limit?
- The free tier will support generous word limits per scan. Exact limits will be announced at launch.
- Will it detect paraphrased content?
- Yes. The detection engine uses semantic similarity, not just exact matching, so lightly paraphrased text is also flagged.
