MarkUp.io is a visual collaboration platform designed to simplify the feedback and review process for digital content. It lets teams and clients comment directly on websites, images, PDFs, and videos, making communication clear, fast, and contextual.
Users can upload any file or link, drop comments anywhere on the screen, and instantly share it for review — eliminating endless email threads and scattered feedback. With support for over 30 file types, MarkUp.io is used by design, marketing, and development teams to streamline creative workflows.
Its Chrome extension allows users to create MarkUps directly from their browser, automatically attaching screenshots for better context. The platform scales with teams of any size — collaborators can join as registered members or as guests without needing an account.
By centralizing all feedback in one place, MarkUp.io cuts review cycles by up to 80%, helping teams move from design to launch faster. Companies like Getty Images, Rosetta Stone, and Toptal use it to coordinate feedback across departments and clients.
In essence, MarkUp.io is the “Google Docs for websites” — a fast, intuitive, and frictionless way to review digital projects visually, save time, and keep every stakeholder aligned.
