Instagram is once again cribbing from competitors like Snapchat and BeReal with a new photo-sharing format it calls “Instants,” which are ephemeral photos that you can’t edit and that you can only share with your close friends or followers that follow you back. Instants are available globally beginning on Wednesday as a feature in the inbox in the Instagram app and as a separate app that’s now in testing in select countries.

To access Instants from the Instagram app, go to your DM inbox and look in the bottom-right corner for an icon or a stack of photos. After you post a photo, your friends can emoji react to it and send a reply to your DMs, but after they see it, the photo disappears for them. Instants also disappear after 24 hours, and they can’t be captured in screenshots or screen recordings.

However, your Instants will remain in an archive for you for up to a year, and you can reshare them as a recap to your Instagram Stories if you’d like. You can also undo sending an Instant right after you post it or delete it from your archive.

The Instants mobile app, which popped up in Italy and Spain in April, gives you “immediate access to the camera” and only requires an Instagram account, Instagram says. “Instants you share on the separate app will show up for friends on Instagram and vice versa. We’re trying this separate app out to see how our community uses it, and we’ll continue to evolve it as we learn more.”

Instagram, in its testing, has seen that people “tend to use Instants to share much more casual, much more authentic moments about their day,” according to Instagram boss Adam Mosseri. “And we know that this type of sharing of personal moments with friends is a core part of what makes Instagram Instagram, but we also know that a lot of people don’t really share a lot to their profile grids anymore.”
