Flip (formerly Flipgrid and originally Vidku[1]) was a free-to-use video discussion platform bought by Microsoft for use in classroom environments. The platform was available via a web browser,[2] or through a mobile app on iOS and Android devices. Both the website and apps were fully discontinued in October of 2024 to be implemented in Microsoft Teams for Education instead. The software allowed teachers to post topics arranged in a grid which contain videos and text-based information, and allowed students to submit their own videos in response.[3] Students and teachers were able to add items to the videos they upload including sticky notes and stickers,[4] and the videos uploaded could include automatically transcribed closed captioning.[5]
