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.
