The most intuitive way to read, annotate and collaborate on PDFs. Replace your red pen with a natural, paper-like markup experience built for real work — not just filling in forms.

• Natural markup — ink, highlights, shapes, text, stamps and measurement tools
• Document storage & sharing — keep your files together and share with a link
• Live Sync — your markups follow you across every device, in real time
• Quick Tools — merge, split, compress, convert and sign without leaving the app
• Works everywhere — Windows, macOS, iOS, Android and the browser

A shared workspace for design and construction teams to review drawings and drive work to completion. Turn markups into tracked, accountable tasks — and keep everyone, including external collaborators, on the same page.

• Tasks on the drawing — drop a pin, assign an owner, set a due date
• Custom statuses & threaded conversations — track work and resolve it in context
• Centralised task management — see every open item across the project at a glance
• Unlimited guest access — bring in consultants and clients at no extra seat cost
• Built for AEC — architecture, engineering and construction workflows, end to end
