15 best image annotation tools to use in 2024

How would life change if you could get feedback without the usual email/Slack merry-go-round?

Imagine never needing one more Zoom meeting just to align with stakeholders. Instead of long-winded messages, your teammates could just tag you in a comment.

Alright, alright, enough suspense. You came here to level up your design workflow, not listen to a long-winded spiel.

So you need an image annotation tool. Simple as that.

But what the heck does “image annotation” even mean?

This blog will break it down for you!

Table of contents

What are image annotation tools & why do they rule?

Image annotation tools are like that friend who makes your life way easier, but you didn’t know you needed. They let you leave comments right on designs instead of resorting to the dreaded email/meeting shuffle.

We’ve all been there–banging our heads trying to decipher cryptic client feedback like, “I don’t like the button.” Ummm, which button?! 🤦

Cue the back and forth.

With image annotation tools, comments are placed directly on the design, so there’s no confusion.

Not only do they help decode feedback, but these tools also streamline collaboration for all kinds of workflows. For example, these use cases:

  • Agencies can simplify tedious reviews
  • Marketers can centralize feedback
  • Students and teachers can easily share and grade assignments
  • Remote teams can minimize meetings and chat pings

The benefits don’t stop there. Image annotation tools also:

  • Enable real-time collaboration on designs
  • Shorten feedback loops so everyone stays aligned
  • Streamline the quality control process via real-time feedback
  • Reduce the back-and-forth of email and messages
  • Provide one centralized place to communicate

So, to wrap it all up, these tools can help users at all levels, whether you’re a designer, marketer, student, or remote team. They cut down on wasted time and keep stakeholders aligned.

With all those perks, it’s no wonder image annotation is critical for streamlined workflows. There are two main types you should know about…

Types of image annotation tools

There are two kinds of image annotation tools out there.

First up are image annotation tools for reviewing creative content. These let you collaborate, annotate images, and get feedback on designs right on the platform. 

With MarkUp.io, it’s as easy as uploading your work and inviting reviewers.

The other type of annotation tool is for training AI assistants.

These tools let you label images to create datasets that teach the AI models. It’s how chatbots learn to schedule your meetings, and self-driving cars avoid pedestrians.

Remember how we wondered how AI can tell a pole from a person? It’s trained through image classification to identify objects without human help.

Data scientists use annotation tools to make datasets that show examples of different labels. More labeled data = smarter AI.

So machine learning engineers can use these datasets to train artificial intelligence to label images, drive cars, schedule meetings–you name it.

Specific types of annotation data scientists create include

  • Image classification – labeling objects in images
  • Boundary recognition – drawing boxes around objects so AI can detect edges
  • Semantic segmentation – helping AI identify different but similar objects

Some open source data annotation platforms are VGG, LabelMe, COCO, and more.

But enough tech talk–you came here for simplified image reviews!

Now that the two main categories are nice and defined, here’s a spotlight on some top creative content annotation tools.

The top contenders for simplifying image reviews have been rounded up. Their prices, features, and capabilities are compared side-by-side, so you can see how they stack up.
