MediaPiper
Hover any image or video to instantly preview the full-size version. MediaPiper automatically discovers full-resolution URLs, upscales with on-device AI, and gives you professional-grade media controls — all inside a floating popup.
Intelligent Discovery
Traditional image-preview extensions rely on fragile, hand-maintained site rules that break whenever a website changes its code. MediaPiper replaces that with an adaptive discovery engine that learns patterns on its own.
Canary Pairs
The engine samples page images, identifies thumbnail-to-full-size URL patterns, and verifies them. If a pattern changes, it re-discovers automatically.
4 Resolution Strategies
Substitution (template URLs), Mutation (regex/param/host transforms), Fetch (HTTP + extraction), and Pipeline (chained steps). All declarative — no JS eval, no sandbox.
Bundled Sieves
Pre-configured rules for Imgur, Reddit, Flickr, Twitter/X, Pinterest, and other popular sites. Eliminates cold-start delay while flowing through the same verify-and-resolve path as discovered rules.
Smart Prefetch
Configurable pre-resolution tiers — Off, Light, Moderate, Aggressive, YOLO, or Custom — with per-domain probe limits, delays, and timeouts.
