Are you looking to improve review and approval processes? Wondering what’s the best content approval software to use?

FACT: Collaborating on content gets so messy sometimes. Great ideas get lost in endless email chains. Feedback and comments often lack context, making them impossible to act on. And even when you’re trying to explain them better, there’s still something missing.
But it all changes when you can add comments directly on the piece of content. When you can annotate an image or video, leave comments beside a paragraph of text, mark elements on web pages that need changing, etc.
Enter annotation tools, software that allows content creators to do just that.
In this guide, you’ll discover 13 of the best annotation tools today and learn how they can improve your feedback and approval workflows.
So, let’s get to it.
What Exactly is Annotation Software?
The term – annotation software – refers to tools that allow you to mark and draw on other files – images, videos, text files, PDFs, and more – to provide precise comments and instructions.
Different annotation tools use different types of annotation, from simple text comments and notes to allowing users to color-code and label elements of a document, add signatures, and more.
When to use the annotation software?
Organizations use annotation tools in a variety of situations. Here are just some examples:
- Many companies implement annotation software to comment and provide contextual feedback on content assets across the entire content production process. Such platforms help team members provide more meaningful feedback that can be acted on quickly.
- Annotation tools help teachers highlight important passages in text files submitted by students.
- Many organizations use annotations to add suggestions for improvements to various assets they work on and data and other file formats.
- Teachers and educational institutions often use collaborative annotation to help students develop their reading, writing, and critical thinking skills.
Overall, annotation tools are ideal when you need to provide meaningful feedback and leave comments directly on a file or a data set.
But there’s a problem, right? Search for annotation tools in Google, and you’re immediately overwhelmed by the number of options available.
How do you decide which software to use?
Here are some suggestions for how to evaluate the tool. And further down in this guide, you can review 13 of the best annotation tools today to evaluate for your annotation process.
What to Consider When Selecting an Annotation Tool
Most annotation tools focus on specific uses or use cases. Some help with annotating files. For others, annotation features are only part of a larger project management platform that helps companies deliver content more efficiently.
For that reason alone, you should evaluate each tool against these three criteria:
Consider what you will be using the tool for. Do you need it just to annotate files? Or does your team struggle with creating content efficiently? Some annotation tools will help you improve feedback; others will also provide features to scale content production.
Each of the tools on our list has its distinct set of features. So, as the first thing, check whether the software’s key features match what you’ll be using it for.
#2. Annotation capabilities
Secondly, different tools focus on different file formats. Most allow marking up text or PDFs. Many offer image annotation options, and some also allow you to annotate videos or databases.
When evaluating annotation tools, also pay attention to what file types the tool works with.
Annotating files seems simple to do. But from the software point of view, it’s a complex process that requires adding more information to an existing file. Some tools handle this better than others. They work slower on certain file types and may even struggle to process more complex assets.
So, if you find tools you like, take them for a trial. See how well the tool performs tasks and if you’re happy with the speed and efficiency.
With all that in mind, here are the best annotation tools to consider.
