Product summary

Review the store description, core capabilities, and common use cases.

MarkLayer turns any website into a visual review surface. Toggle the overlay and you can inspect the box model of any element, live-edit its text, colors, fonts and spacing, drop anchored comments, and draw arrows, boxes and highlights directly on the page — no code, no rebuilds.

When you're done, export everything to a single JSON file. A teammate picks "Import & open" from the toolbar, and MarkLayer opens the right site and re-applies your comments, edits and drawings automatically — even across multiple pages and single-page-app routes.

FEATURES

• Inspect — hover to see margin / border / padding, size, colors and fonts; click to copy a resilient CSS selector.

• Edit — change text, text/background/border color, font size & weight, alignment, spacing, radius, opacity, width/height, and an element's link (href) or image (src/alt). Every change is reversible.

• Comment — drop pins anchored to elements, with author names, threaded replies, and resolve.
