Markup Relay: Open-Source Visual Annotation Tool for AI Coding Agents
English summary
SUB&SUB studio has released Markup Relay, an open-source browser-based tool that lets users annotate images and videos to help AI coding agents understand visual context. Files can be dragged in and annotated with a selection tool; unselected areas are automatically blurred. For videos, keyframes are extracted to describe dynamic changes. Processed files are uploaded to Cloudflare R2 and automatically deleted after a set time. The team is seeking feedback via ProductHunt.
