Make feedback visible. Highlight the problem, draw the change, add a note, and share an annotated capture. Mark brings desktop annotation to Mac and webpage annotation to Safari on iPhone, iPad, and Mac. DESKTOP TOOLS ON MAC Keep a compact floating palette beside your work. Mark up app interfaces, designs, documents, and webpages on your screen. Use colored highlights, shapes, freehand drawing, and notes. Inspect small details with the desktop magnifier, then capture your annotated screen. Choose a palette layout and appearance that fit your workspace. Desktop annotation and magnification are Mac features. SAFARI EXTENSION INCLUDED Annotate webpages directly in Safari on iPhone, iPad, and Mac. Highlight text and regions, draw squares and circles, sketch arrows and underlines, and add sticky notes beside the content you are reviewing. CAPTURE, ORGANIZE, SHARE Keep saved images in Library, organize them into folders, open previews, and share through the system share sheet. On iPhone and iPad, new Safari captures are also available in the native Mark Library. Saved captures remain accessible after tool access ends. VISUAL CONTEXT FOR YOUR WORKFLOW Use annotated screenshots for design reviews, bug reports, writing feedback, and visual context in an AI-assisted workflow. Share an image with the app or person you choose. Mark does not include an integrated chatbot or generative service, and the personal release does not include live team collaboration.
