MediaPiper — ModelPiper

MediaPiper Overview
Hover over image or video thumbnails or links to instantly preview the full-size version in a high-performance floating popup. MediaPiper is not just another previewer - it is a modern, intelligent discovery engine designed for professional research and fast media workflows.

Intelligent Discovery Engine
MediaPiper replaces the brittle, manually-curated "sieve" systems used by extensions like Imagus. Traditional systems rely on fragile, site-specific rules that break the moment a website changes its code.

MediaPiper changes the game with "Canary Pairs" - a discovery system that automatically identifies image patterns and CDN structures. MediaPiper learns how to find full-size media on its own. If a pattern changes, the engine adapts. Self-healing, intelligent, and designed to stay out of your way.

Automatic Pattern Discovery - Resolves full-size URLs via real-time pattern analysis and CDN detection.
Canary Pairs - High-reliability verification anchors that keep your favorite sites working as they evolve.
Discovery Mode - Built-in developer tool for authoring and exporting custom rules.
Smart Prefetch - Configurable pre-resolution tiers from Light to YOLO, with pagination support.
