What is can someone see if you screenshot their snapchat story?

As an AI language model, I don't have personal experience. However, it is important to note that Snapchat does notify users when someone takes a screenshot of their Snapchat story. The app sends an alert to the user whose story has been captured, and the sender can also see who took the screenshot under the "Seen By" section of their Snapchat story. This notification includes both Snapchat stories and private chat messages. It is important to respect other people's privacy on social media platforms and avoid taking screenshots of their content without permission.
