If you see someone’s story on Snapchat and want to edit it and send it back, you can do so with Snapchat’s remix feature. This lets you take a photo or video of yourself with your friend’s story also on the screen, and then send it to them.
How to Send a Snap to Everyone at Once
You can resend a snap from a friend’s story, as long as you’re replying to the story itself. You can’t remix snaps that people send you directly, but you can remix snaps in your Memories. Here’s how to remix a snap from someone’s story.
Tap and hold anywhere on the Snap in the story you want to remix.
When the menu appears, tap Remix Snap.
