The feature can be accessed using the memories icon at the bottom of Snapchat's home screen interface. Selecting "A Look Back at 2017" automatically generates a Story around your timeline of pictures, but the arrangement can be tweaked by selecting "Edit Story" and tapping the X on individual snaps to remove them from the collage. The Story can then be saved and shared with friends.
As The Verge notes, the "Look Back" feature may not appear if there isn't enough media from the last 12 months to create a story, so only avid Snapchat users are likely to see it.
Facebook continued its seemingly relentless trend of copying Snapchat features last month, when it began testing a new feature that plays on the latter's chat streak challenge, which encourages users to "keep your streak going" when messaging friends.
Prior to that, Facebook created a carbon copy of Snapchat's day-long, vanishing post idea in Facebook Messenger, WhatsApp, and Instagram, which gained 100 million users following the update last year. The company also previously aped Snapchat's face filters and rewinded video features for Instagram, which also proved a hit.
Today's feature debut follows news yesterday that Snapchat is testing a feature which will let users share stories outside of the mobile app, in an effort to boost sign-ups to the app.
