When you paste your document into the Grammarly iPhone Editor, the formatting is automatically removed.
As a workaround to this issue, we suggest uploading the document to the desktop version of the Grammarly Editor. To learn more about preserving formatting on a desktop computer, check out this article.
Alternatively, if you are writing your text in any other text processor, you can take advantage of the Grammarly Keyboard and check the text directly in that text processor.
