Magic Guide ToolMagic Guide Tool
Chrome Extension · Web Design & QA

Do design review and QA
right on any live webpage —
like Photoshop, in your browser

Pull rulers & guides, box and annotate issues, draw vectors, capture full pages, and overlay your mockup on the real page — then export a tidy annotation report straight into your own Google Sheet. No sign-up, no login; your data stays local.

Available in 9 languages — Traditional/Simplified Chinese, English, 日本語, 한국어, Deutsch, Français, Español, Português

One side panel for your whole design review

No more screenshotting into another app — work right on the real page, WYSIWYG.

📐

Rulers & Guides

Drag horizontal/vertical guides from the rulers with live coordinates and spacing; remembered per URL automatically.

🔢

Region Annotations

Box any area, auto-number it, add notes; hide numbers, customize colors. The fastest way to flag bugs or design feedback.

✏️

Vector Drawing

Arrow, line, rectangle, ellipse, triangle, star, check, cross and freehand — with notes and aspect-ratio lock.

🖼️

Custom Image Stamps

Upload your own images as reusable stamps and build a thumbnail library.

📸

Full-Page Screenshot

Scroll-stitch the entire page into a single image.

🪟

Design Overlay

Lay your mockup semi-transparently over the live page to compare pixel accuracy.

📤

Export Report

Write region annotations (with screenshots) row by row into your own Google Sheet — delivery and tracking in one go.

🔒

Your data stays yours

Guides, annotations and images live only in your browser. The only outbound transfer is the report you export — and it goes only to a Google Apps Script you deploy yourself.

Start free, upgrade to PRO when you need it

Core tools — rulers/guides, region annotations, vector drawing and full-page screenshots — are free.
