Saving a video for personal viewing, or to send to a friend, is what this tool is built for. Reposting someone else’s content as your own, stripping their username in the process, is a different thing entirely — it’s a courtesy issue and, depending on the platform and the content, can be a real copyright issue too. If you’re reusing a clip publicly, the simple fix is to credit the original creator the same way you’d credit a quote: name them, and link back to the original post where you can.
