The most helpful feature of MarkUp.io is its ability to allow team members to leave comments and suggestions directly on a website, streamlining the design review process. The platform's intuitive interface makes it easy to use, and the real-time updates and notifications keep everyone on the same page. The ability to assign tasks and track progress is also a helpful feature for managing projects. Additionally, integrating with popular tools like Slack and Trello makes collaboration even more seamless, which is very helpful for remote teams.

Ease of use (especially for the clients)

I really like the pinned feedback commenting system in Markup.io, which is almost similar to other tools like XD, Figma, and Invision. The ability to leave feedback on desktop, tablet and mobile versions of a website without leaving the browser is a huge plus. I also appreciate the publicly sharable links feature, making it easy for my team to view and respond to feedback on a certain image or website.
