What it does

Capture anything on the web

A built-in browser lets you navigate to any page, then grab the whole tab or a single window. No browser extension, no second app.

Mark it up in seconds

Drop arrows, rectangles, highlights, and text callouts onto the canvas. Drag, resize, snap. The toolbar stays out of your way.

Export a clean PNG

⌘⇧E gives you a high-resolution image — perfect for sticking in a Slack thread, a design review, or a bug report.

  • Every breakpoint in one click. Pick your viewport sizes — widescreen, laptop, tablet, mobile — and grab the same page at each in a single capture run.
  • Full page or just what's visible. Toggle between snapshotting the whole scroll height or only the part you can see right now.
  • Tabbed browsing, captured. Open multiple URLs in the built-in browser, jump between them, and capture from whichever tab you're on.
  • Color-coded review cards. Critical, warning, and approval notes — pre-styled so feedback stays readable on any screenshot.
  • Crop without losing pixels. A floating crop tool trims images non-destructively — re-crop or restore the full image any time.
  • Pull URLs from your real browser. Grab the front-tab URL straight out of Safari, Chrome, or Arc — no copy-pasting addresses.
  • Capture a window from any browser. Already have the page open in Safari or Chrome? Pick its window and screenshot it directly, useful when you're already logged in elsewhere.
  • Two tabs, one document. Capture on the left, annotate on the right. ⌘1 and ⌘2 flip between them instantly.
