HOW IT WORKS
Less work beyond what you see.
Content remains in the document. Supported sections far from view can skip layout and painting until you approach them.
Skip offscreen rendering
Uses native content-visibility containment rather than deleting nodes or rewriting the website.
Restore content on approach
Viewport-aware observation and cached scan regions bring nearby elements back as you scroll.
BUILT FOR REAL PAGES
Quietly useful. Fully in control.
Long-form content
Designed for lengthy AI conversations, documents, tutorials and image-rich feeds.
Incremental scanning
Tracks structural changes in cached regions instead of rescanning the entire page after each update.
Live diagnostics
Inspect managed blocks, offscreen coverage estimates, scan counts and local scan work.
Your choice per website
One automatic optimization strategy, plus a global switch and a site-specific on/off control.
