Show HN: Mago, an open source AI video studio, runs locally with Comfy

Mago Studio is a local-first desktop AI video editor for Windows, macOS and Linux that keeps projects and videos on the user's machine, rendering on their own GPU through ComfyUI or in Mago Cloud when signed in. It offers script-to-video direction with cast, shot lists and storyboards, plus frame-accurate restyling of footage using masks, relighting and character replacement. The code is AGPL-3.0 and designed to be modified by AI agents; local rendering is free, while cloud models are paid and require a Mago account.
