Snapchat is a multimedia messaging and social media application for smartphones where users can send ephemeral photos and videos ("snaps") that disappear after being viewed. Key terms include Snaps, the temporary photos or videos users send; Stories, a collection of snaps visible to friends for 24 hours; and Streaks, a feature that tracks consecutive days of snapping between two users. The app also uses computer vision for features like filters and lenses and includes a "Snap Map" to see friends' locations and "Spotlight" for short-form videos.
