Instagram has unveiled a new feature named Instants, designed for sharing spontaneous and unfiltered photos with friends. This feature allows users to send photos that disappear after being viewed, adding a layer of privacy to sharing. Instants can be accessed through a dedicated companion app, which provides quicker camera access and is currently rolling out on iOS and Android in select countries. Users can choose their audience, and while the photos are ephemeral, they can be saved in an archive for up to one year. The feature also allows users to add captions and includes an Undo button for retracting shared content. Reactions and replies to Instants will be directed to the user's direct messages, enhancing interaction among friends.
