9 best web annotation tools for Chrome (w/features & pricing)

You’re reviewing the final version of a new website your team has built for a client when you spot a mistake. You take a screenshot, open it in Microsoft Paint, circle the part of the design that looks off, and save the marked-up screenshot to your device. Next, you attach it to an email and send it to the designer, along with a wall of text that explains what you want them to change.

You hit send, sigh and wonder out loud:

“Isn’t there a better way to annotate content!?”

We included MarkUp.io in our Chrome tools list because of its powerful Chrome extension. This enables users to mark up web pages with the click of a button.

With MarkUp.io, users drag and drop deliverables onto their workspace to create MarkUps, link-enabled shareable copies of their content.

MarkUps can then be shared via link or email with anyone. Once the invitee accesses the MarkUp link, they can click anywhere on the deliverable to leave contextual comments, called pins. There is no need to download any additional software. All reviews take place online and are accessible to all project members.

Similarly, the MarkUp.io Chrome extension allows professionals to create MarkUps of entire web pages just like they’d bookmark an interesting blog article.

Who is MarkUp.io for?

  • Permissions for better control over who can do what
