What is web annotation?

Web annotation is the practice of adding comments, highlights, and drawings directly on top of a live webpage so collaborators can see feedback in its real context. AnnotateWeb is a free, no-signup tool that does exactly this in real time: paste any public URL, mark it up with highlighters, shapes, and text, then share a permanent link that works on any device — or export the result as a PNG image. Sessions stay private, accessible only through their unique link, and annotations automatically delete after 2 minutes of inactivity. Designers, developers, educators, researchers, students, and marketing teams use AnnotateWeb to give precise visual feedback on websites and mockups without installing anything or creating an account.
