Since Wordtune's outputs are trained on a wide range of English texts, rather than from a single source, it is highly unlikely that our language model would suggest a plagiarized piece of text verbatim. However, we can't guarantee the suggestions not being flagged by a specific plagiarism checker.
Also, when using the Spices feature, factual outputs will include cited sources linked in the suggestion card (as seen below), which helps a lot in the effort to avoid plagiarizing.
