Want to make learning more visual and engaging with online annotation?

Harmonize makes it a cinch.
Promote social & inclusive learning

Encourage student collaboration

Increase opportunities for students to work with one another with video, image, and text annotation. From one-to-one peer reviews to group discussions, rich annotation features allow students to provide each other with richer feedback, identify key points for clarification, or highlight important details for discussion.

Online annotation helps better connect students and reduces the barriers that often hinder collaboration and discussion in online or blended learning courses.

Promote inclusive learning

Traditional online tools usually only allow students to contribute and receive feedback in one way. With online annotation included in your suite of multimedia discussion & collaboration tools, you can create a more effective online learning environment for diverse learners.

Fully accessible video, image, and document annotation features gives students an additional way to contribute to discussions. It also gives students a clear and visual way to receive seamless feedback from others and the instructor so they can improve.


Easily provide feedback

In addition to auto-grading participation and using rubrics to assess student performance, video, image, and even PDF annotation allows instructors to pinpoint key areas for improvement or praise. 

Detailed feedback pointing to specific examples in students’ work helps them better understand your evaluation and path toward improving. It also saves you hours of valuable time grading.

Online Annotation Tool

Technology has changed nearly every aspect of life over the past few decades, and education is no exception. One of the more recent developments in education is the expansion of online learning. While online learning is not a new concept, online or blended learning has become more common, leading to many exciting new tools and techniques for creating better online learning experiences.

One such tool is screen annotation software for higher education. An online annotation tool allows instructors and students to collaboratively highlight and comment on digital text, similar to using a highlighter marker and writing in the margins, only digitally.

Instructors can incorporate online annotation tools into their LMS-powered courses to encourage better discussions, improve student engagement and retention, and simplify facilitation and grading. While LMSs often power online learning, online instructors may find themselves wondering how to annotate within LMS software. Unfortunately, this capability is not built into every LMS.

However, instructors can still incorporate social annotation tools into their courses by integrating annotation software into their LMS environments. There are many kinds of online image annotation tools for education, like automatic image annotation tools. It’s also possible to find other kinds of annotation tools like a text annotation tool online.

Harmonize is an example of one of the best online tools for annotating text, images, and videos. As part of a comprehensive suite of discussion and collaboration tools, Harmonize’s online annotation features can help instructors improve student engagement in online courses. Let’s explore some of the specific ways annotation software can benefit students and instructors in a variety of remote education contexts.

Image Annotation Tool

In an ever-evolving, digital world, instructors who facilitate online or hybrid courses need an easy way to annotate images online? Without an image annotation tool, instructors have very little means to assess and provide students with real-time feedback to improve.

Online education introduces new opportunities for communication inefficiencies. When an instructor needs to share an image with students for them to discuss, comment on, or use as a visual aid to complete an assignment (to name just a few examples,), things can get confusing quickly. In online environments, students can’t simply point to the picture to refer to different details or write on a physical copy and hand it in. The same problem arises if the instructor needs to label images or provide feedback. Clearly, there needs to be a better way to annotate images.

Fortunately, tools like Harmonize exist that make it much easier for students and instructors to discuss images online. Using the best image annotation tool can go a long way towards improving engagement in your online courses.

Instructors can use an image annotation tool to easily label images or provide specific instructions, and students can write comments or questions directly on the image. Discussions can become more collaborative when everyone has access to image markup capabilities. As a more interactive approach, students may even enjoy the more dynamic method of communicating with classmates rather than dread sitting down to write their discussion posts for the week.

Online Text Annotation Tool

Higher education instructors can also use online text annotation tools to improve their courses. While images and videos are great for generating engagement from learners, there may still be times when it’s necessary to annotate text. It’s also important to cater to every learning style. Some students may feel most comfortable contributing to discussions with text — others may need to use text-only to accommodate their needs.

Harmonize offers many text-based features like text chat, auto-captioning, and Q&A boards. Features like these can make it easy to provide all kinds of learners with equal access to online materials, ensuring everyone is able to participate in discussions with instructors or classmates.

One of the goals of social annotation software for online education is to create a more comfortable and engaging learning environment for students. Many of Harmonize’s text annotation features mimic the feel of popular social media platforms to make the experience simpler and more engaging for students and instructors alike. For example, instructors (or classmates) can “tag” students in discussions to mention someone specifically and pull them into a relevant conversation they hadn’t joined yet.

There are also ways to automate text generation using an annotation tool like Harmonize. If an instructor is wondering how to annotate an article that’s read aloud in a video, for example, they could use a text annotation generator to automatically add captions to the video.

Video Annotation Tool

Effective online courses make good use of a wide variety of media — likewise, digital annotation tools cover many different kinds of content. A video annotation tool works very similarly to an image annotation tool, except, as the name suggests, it’s used to annotate videos online. Combining annotations with a dynamic educational medium like video is a great way to improve engagement and communication with students in online learning settings.

There are a lot of different ways students can benefit from a video annotation tool. Online classes frequently utilize videos, whether they’re supplementary materials or instructional videos recorded by the instructor themselves. However, discussing these videos remotely can be challenging. The best video annotation tools make it easy for students and instructors to collaboratively interact with videos as easily as if they were sitting in the same room.

For example, instructors can leave feedback with time-stamped comments on video presentations submitted by students, making feedback on a particular part of the video crystal clear. Instructors can also provide instructions directly within a video if the video is part of an assignment. Instructors can even add shapes or other indicators to videos for added visual aid when necessary.

Online Annotation Tool For Students

One of the most common problems online educators face is finding ways of increasing student engagement. Many elements of traditional classes are missing from online education environments, and this can make it more difficult for students to remain engaged. One way of making asynchronous discussions more engaging is by incorporating dynamic content like images and videos. However, images and videos sometimes introduce a new problem. It’s difficult to reference them directly in text form, making discussions tricky.

Without an online annotation tool for students, it’s hard for instructors and students to communicate effectively about details in videos or images. Online student retention and engagement in higher education is much more achievable with an effective annotation tool for Windows or whichever operating system you and your students use.

Here are a couple of the benefits of image, video, or text annotation tools for students:

Deeper discussions

When students can leave comments directly on images and videos, they can express themselves more clearly, which can lead to much better discussions. Rather than struggle to describe what they’re talking about in a separate post, students and instructors can collaboratively manipulate images and videos to highlight questions, comments, or insights about specific aspects of the learning material.

Improved retention

Everyone learns differently, but many learners find it easier to retain information they saw or heard than information they read in a long thread of text. Online annotation tools can make it easier for students to retain what they learn in discussions because they can associate the information with the image or video.

Annotation Tool For Teachers

The usefulness of annotation and image markup tools extends beyond student engagement strategies. Shared annotation tools also introduce a lot of benefits that make life easier for instructors. Here are a couple of standout examples:

Deeper connections with students

Digital learning tools like LMSs are great for a lot of reasons, but one drawback is that they sometimes make it harder to develop connections with students. Instructors can use annotation tools to provide better instructions and feedback, but they can also use them to encourage students to share their thoughts more often and connect with the material on a deeper level. By removing the barriers that clunky, text-only discussions create, online annotation tools make it easier for instructors to get familiar with every student’s viewpoint.

Lower chance of instructor burnout

Teaching is hard work. For instructors at higher education institutions, digital learning tools can sometimes feel overwhelming. Harmonize’s annotation tools can help teachers more easily manage grading and feedback by offering auto-grading and providing activity reports that streamline student feedback and assessment.

Annotate App

Online education continues to gain popularity, and digital learning tools are developing rapidly. It can be difficult to keep up and compare them, and knowing which tools are the best ones can seem impossible. When it comes to online annotation, there’s a wide range of options. You could use websites that annotate for you, but this kind of solution doesn’t provide many ways for students to add their own annotations. Combining a text annotation tool with an online discussion platform is usually a better solution.

Harmonize is one of the best text annotation tools for turning an LMS into a blended learning platform that combines traditional online discussion features with dynamic annotation capabilities. Some of Harmonize’s most notable benefits include:
