When copying text from a webpage or Word document, there may be many styles present in the text. Using a plain text editor can clear all styles, leaving only the text characters themselves.
If you're just looking for a lightweight editor to do simple formatting and editing on small amounts of text, without all the heavy features of a rich text editor, then a plain text editor will be your best choice.
You can also use a plain text editor to convert a piece of text and download it as a plain text file, save it to your local device, as a text-to-file converter.
Of course, if you want to use it to temporarily store a piece of text, that's also fine. When you input content into the plain text editor, it will save the text to the browser's database. Even if you refresh the page, the saved content will not be lost.
