Facebook isn’t ready to let go of how last summer’s viral ALS Ice Bucket Challenge sent its video views through the roof.
The social media giant launched on Wednesday the standalone app Riff, a collaborative video platform that allows you to invite your friends to stitch together clips under a certain topic, Facebook said in a statement. Since the video is viewable by your participating friends, their friends start can adding videos as well.
“The potential pool of creative collaborators can grow exponentially from there, so a short video can become an inventive project between circles of friends that you can share to Facebook, or anywhere on the Internet, at any time,” product manager Josh Miller said.
Miller told TechCrunch that Riff’s collaborative nature was inspired by how people tagged one another to film and post ALS Ice Bucket Challenge videos, 17 million of which were shared on the site between June 1 and Sept. 1.
Riff also appears to be inspired by how so many Ice Bucket Challenge videos were stitched together—including celebrity and “fail” compilations—similar to the viral “Harlem Shake” videos in 2013, or the never-ending compilations of funny Vines. Riff’s social element will put it in competition with similar apps like Vyclone, MixBit and Snapchat’s Stories.
Riff is available now for iOS and Android.
