Magic Guide ToolDo 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.
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.
