How to make a fake Messenger chat
Name the two people, then add messages for each side with the plus buttons under the messages. Already wrote the story somewhere else? Open Paste a conversation, put each message on its own line like "Emma: Did you find it?" and press Use conversation. The tool sets up both people for you.
The preview redraws as you type, in a white Messenger-style layout with light grey bubbles for the other person and blue ones for you. The header is a circle with the contact’s first letter and their name, so you never need a profile photo.
