Annotation Editor
Arrows, shapes, text, numbered callouts, freehand drawing, and a blur tool for sensitive info. Every tool has a single-key shortcut. Annotate, copy to clipboard, paste — all in one flow.
Draw anything directly on your screenshot. Circle something important, underline text, sketch an arrow by hand. Three stroke widths available.
Point at exactly what matters. Click the start point, drag to the end. Clean, straight arrows that make your point immediately clear.
Rectangles, ellipses, diamonds, and lines. Outline a region, highlight a section, or frame an important element. All shapes are stroke-only so they don't obscure content.
Click anywhere to add a text label. Type your note, pick a color, done. Useful for adding context, naming elements, or writing step numbers.
Auto-incrementing numbered markers. Click to place callout 1, 2, 3, and so on. Perfect for step-by-step instructions, labeling UI elements, or referencing specific areas.
Drag over sensitive information to blur it out. Personal data, API keys, email addresses — blur them before sharing. The original pixels are destroyed, not just hidden.
Pick from six predefined colors that stand out on any background. Switch colors between annotations to keep things organized.
Thin for subtle markups, medium for normal use, thick for emphasis. Each tool respects the current stroke width setting.
