Chrome extension 
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!?”
Duh! We wouldn’t write this article if there weren’t a better way to annotate content in your Chrome browser.
Let’s look into the best web annotation tools for Chrome and check out their features and pricing so you can say goodbye to doodled screenshots forever.

Best web annotation tools for Chrome: comparison table [features & pricing]
We’ve found nine of the best annotation tools available for the Chrome browser and developed a list to help you choose the best for your needs. Whether you’re marking up content for school, work, or personal research, we’ve included annotation tools in the form of Google Chrome extensions and standalone platforms.
Before getting into detail on each tool’s features and pricing, here’s an overview of everything we’ll cover.
We’re diving in head first with MarkUp.io.
Tool #1: MarkUp.io
MarkUp.io is an annotation tool for collecting contextual feedback on digital content the easy way.
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.

- Permissions for better control over who can do what
- Keeping track of changes that have been made, using screenshots that the Chrome extension automatically takes with each comment made
- Switching between the comment and browse mode, which allows users to leave comments throughout an entire website rather than one page at a time

To get the best out of MarkUp.io, we recommend you try the Pro plan, which starts at $25 per month. It includes:
- Unlimited MarkUps
- 500 GB of storage
