"The Choppity team have been shipping new updates to the product which I am quite happy about. It's getting faster and they are also giving us the features we've been asking for!"
Amy L.
Finance creator
"In the past I've tried to get my YouTube video editor to create mass amount of short form content, but they struggled. Economically it didn't make sense and the quality wasn't great. Choppity has been an INCREDIBLE asset in scaling up my short-form video reach. Having ALL the clips automatically clipped, styled and ready to publish has been the biggest lever to growing my businesses."
