“When we uploaded a video to chopcast, it created auto-clips that overlapped 70-80% with ones we manually picked before, except this was done in minutes!"

“I'm paying and love the tool. It has saved so much time editing shot clips from the High Tech Sales Podcast”

"I've tried a few different tools for video clips, but nothing has been as seamless as Chopcast. I use it to create short clips out of long form podcast videos for YouTube, Instagram, Facebook, Twitter, and TikTok."

"Chopcast helped me to identify tips I was sharing with clients anyway and to repurpose those on social media. I've had a couple of clients connect back in with me because I have been sharing videos."

"We do so many webinars. Before, we were taking our webinars and slicing them ourselves, and that wasn't efficient. I would say we get a better output faster and time back working with chopcast."

“Game changer. We just upload our longer videos and turn them into social media-savvy content in just a few clicks. Subtitles and all!”

"Working with chopcast we could post-produce microcontent of the highlights from sessions we've recorded. It saved us so much time. They can self-select the best highlights to be distributed on social. They'll see opportunities in what you're creating that you don't see. It's been a great partnership.
