Edji is a versatile educational tool that combines reading and collaborative annotations to create a unique classroom discussion focused on a text, image, or PDF.

Try it out! Edji is free for any teacher to try, and students do not need an account to start reading and annotating.


Check out this video from our teacher co-founder to learn a little more about Edji!


Easy Reading Sharing

With Edji, it is super easy to get a reading in front of your students. To get a reading into Edji, all you need to do is copy and paste or upload your material it into the Edji new reading editor.

Note: You are able to have multiple groups reading the same text.

Every group has a unique, 4-character Lightning Code associated with it. Anybody can enter this code from the home page. Students can either log in with their own account or quickly create a temporary guest account. If they are accessing your reading as a guest, they will only need to enter their name.

With Edji, you can get your whole class reading in seconds!

Codes are short and easy to type. Enter this code into Edji and check out this reading!

Collaborative Annotation

Annotating and connecting to text is what helps us learn from what we are reading, and distributing standard digital PDFs doesn’t allow for any collaboration. Edji brings back the interaction with active annotations through emoji, text and audio. Adding annotations is easy as highlighting and allowing readers to choose the comment type that they feel would be best for expressing themselves. Each comment type has their own individual strengths. Try having your students analyze a passage and summarize the main idea with emoji, or have them pronounce foreign language words to the best of their ability with an audio comment.


Students can comment on the reading and reply to each other to encourage collaboration.

Heat Mapping

As annotations are made, you are able to see what is being highlighted and what is being said, not just by one student, but for your whole class, all at once. When a sentence or phrase gets commented on more than once, that area will generate ‘heat.’ The area will begin to change from the regular yellow of one highlight to orange for a few highlights, to a bright red when many students have commented on the area. This can bring your attention to the areas that students find the most important about what they are reading. If those areas are what you wanted your students to focus on, great! you can use their comments to generate discussion by asking specific ‘Why?’ questions about their comments. If your students aren’t commenting on what you thought they would, you can learn why they focused on where they did, and use this information when planning your lesson about the Reading.

This is what heat vision can look like in your classroom. Parts of the text with more comments glow red to show activity.

You can use the heat map to help your students scaffold each other’s reading experience. By clicking the Heat Vision button on your teacher toolbar, students will be able to see and interact with each other’s annotations. Heat Vision opens up so many opportunities for student collaboration that are not possible in standard annotating exercises.

Edji does have a premium version called Hero. With Hero, you’ll have the ability to have as many active readings as possible. You will also have access to additional student analysis tools. Learn more about Hero!
