Summary Generated by Built In

Kapwing is building the next generation prompt-to-edit platform for video creators. Our mission is to make content creation fast, accessible, and collaborative. In doing so, we enable everyone to share their story online. Kapwing has two products:

- Kapwing AI: A prompt-first AI editing companion that helps creators refine visual content. Instead of learning complex design software, users can chat with Kai to explore content ideas instantly in the browser. Kapwing AI launched in Fall 2025, and leverages the best LLMs and generative models to empower users to ideate, edit, and generate images, videos, and audio.

- Kapwing Studio: An online video editor that is collaborative, powerful, and easy to use. Millions of creators every month choose Kapwing to tell their story and bring their ideas to life.


Kapwing turns video editing, traditionally a heavyweight, time consuming workflow, into a joyful, collaborative experience. We believe that we can use technology to augment the video editing and content creation experience, and we've already started on this path with a wide array of templates, plugins, and new pipelines for combining tooling with the best AI models.

What We Do

Video editing is the final frontier of software tools moving to the cloud. We're making the next generation of modern creators tools to enable everyone to share their story online. Join us at Kapwing on our mission to make content creation fast, accessible, and collaborative. Everyone is a creator. The problem, however, is that today's tools get in the way of expressing our creativity fully. Especially when it comes to video, the gap between an idea and a video is wide enough that it's hard to even start. Our mission at Kapwing is to make content creation easier and more accessible. Our main product, Kapwing Studio, is an online video editor that is both powerful and easy to use. Millions of creators every month choose Kapwing to tell their story and bring their ideas to life. Our vision is to build a modern video editing platform that serves as the go-to tool for anyone creating video for Youtube, social media, or work. Being in the browser allows us to turn video editing, a traditionally heavyweight, time consuming workflow, into a joyful, collaborative, and fully-featured experience. We believe that we can use technology to augment the video editing and content creation experience, and we've already started on this path with a wide array of templates, applications of artificial intelligence, and new pipelines for exporting and video processing. While software is the core of our product, being creative is the core of our work. Every team at Kapwing, from engineering to content to customer success, values trying new things, moving quickly, and helping creators in new ways. Join us on our journey to democratize creative tools and invent the future stack of video creation.
