No tracking.Zero telemetry, zero analytics, no server that sees your browsing. See the architecture.
Works across the open web.Optimized plugins for image search, social, shopping, photography, and news sites — plus generic hover-zoom anywhere else. Browse the catalogue.
AI upscaling, on-device.Pro reconstructs detail in low-res photos as you hover — Real-ESRGAN runs locally, no image leaves your browser. See the release.
Installs without the scary warning.No host access is requested at install time — Chrome never shows “read and change all your data on the websites you visit.” Broad access is optional, and only for Pro features that need cross-origin pixels. How that works.
