Vizard.ai is an online AI video editing platform designed to convert long podcasts, webinars, and interviews into bite-sized, social-ready short clips.

It also provides built-in brand kits, social media auto-scheduling, and direct publishing capabilities. Vizard operates on a credit-based system where usage is determined by the total minutes of source footage uploaded.
