Kozy: an online tool for quickly editing short videos with text descriptions

General Introduction

Kozy is a quick video editing program that uses text descriptions to create short videos. At its core, it allows users to generate professional-looking short videos in seconds with simple verbal inputs, such as "cut a funny pet video". Developed by Tunde Alao and launching in April 2025, the site was inspired by his own tedious experience of editing videos manually. He hopes Kozy will save users time and effort. Currently it's especially suited to short-form video platforms such as TikTok, but it can also handle YouTube videos and advertorials.
