Our annotation tools give you everything you need to mark up any website with ease.
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.
Simple yet powerful annotation tools to communicate your ideas clearly.
Highlight and draw on any webpage to emphasize important content.
