How to Unblur Course Hero

Blurred document

4 ways you can unblur Course Hero documents.

Homework and assignments are a ubiquitous part of a student’s life. There’s no running away from it. But what you can do is run toward some kind of homework help. And Course Hero is one of the most popular websites when it comes to homework help.

With their repository of real assignment questions from real and tangible courses from top colleges and schools, the chances of you stumbling into the exact question you were looking for are pretty high. But the only problem that remains now is that bar a preview, the rest of the content in all documents is generally blurred and hence, not so helpful. Let’s have a look at all the ways you can unblur a Course Hero document, shall we?

The Official Methods

As is the case with most things on the internet these days, there’s an official way, and then there are the unofficial methods, i.e., the tips and tricks. There are two ways you can unblur Course Hero officially – by either buying a subscription or using the free method.

Upload Documents to Unblur Course Hero for Free

The official way to use Course Hero for free is pretty easy. All you need are copies of original notes or documents. The content should be original, i.e., either you own the copyright or have permission from the person who owns the copyright to upload them, and it should not be plagiarized either.

How this works is that after creating a free account, you have to upload your notes or documents to the Course Hero site. After you upload the original documents, you’d have to wait somewhere from a few hours to up to 3 days. When the Course Hero team approves your documents, you’d get free unlocks in an email.

For every 10 successfully approved documents, you get 5 unlocks. You can use 1 unlock to unblur one Course Hero document. It’s good practice to upload extra documents, just in case, as only the ones that’ll get accepted will count towards the number of free unlocks you’ll get. All unlocks you receive after uploading documents expire after 30 days.

Get a Course Hero Subscription

The second official way involves getting a Course Hero subscription. A Course Hero Premier subscription gives you 30 unlocks every month, along with access to textbook solutions and explanations and the ability to ask up to 40 tutor questions. With these 30 unlocks you get every month, you can unblur 30 Course Hero documents. These unlocks refresh every month. And if you have any unused ones, they won’t carry over to the next month.

It also saves you from having to spend time uploading any of your documents. But, hey, if you want to help other students with your notes, you can still go ahead and upload them by all means. It would just mean extra unlocks for you.

You can get a Course Hero subscription for $39.95/month for a month, $19.95/month for a 3-month subscription (one up-front payment of $59.85), or $9.95/month for a yearly subscription (an up-front payment of $119.40).

If you plan on using Course Hero often, a subscription might be the way you want to go. You can also pool some money with your friends and buy a subscription in partnership. But if you plan on using the site scarcely, it might not be the best thing for you.

There are also other official methods to get free unlocks for Course Hero, like making a quiz or rating documents.

You can make a quiz and submit it for any document on Course Hero, but this requires you to have an unblurred document initially. So, this method can be thought of as a way of getting additional unlocks as it isn’t particularly useful in the beginning when you don’t have any unlocks to unblur a document. Each quiz can earn you up to 3 unlocks.

You can also rate other documents on the website to earn additional unlocks. You get 1 unlock for every 5 documents you rate on Course Hero.

Other Methods to Unblur Course Hero

There are some “unofficial” methods you can use to unblur your Course Hero material. But the catch with these methods is that they are device particular and might not always work.

Unblur Course Hero on a PC using ‘Inspect Element’

This method is more of a trick, and if you’re lucky, it’d unblur your Course Hero documents within a matter of minutes. Go to the Course Hero website on the Google Chrome browser on your computer and open the document you want to see.

Highlight the part of the document that is blurred and right-click on it. Select ‘Inspect’ from the context menu that appears.

A window will open on the right that contains the code for the page. In the open window, you’ll find a ‘div’ tag with an anon-hide obscured parameter. You can also use ‘Ctrl + F’ and search for keywords “obscured” or “hide” if you don’t find the div tag right away.

Then, right-click on the tag and select ‘Edit Attribute’ from the menu. Type ‘none’ for the new ‘class’ element and press the ‘Enter’ key.

The blurred document from Course Hero should unblur. Now, remember that this is more of a bug, and Course Hero could fix it at any time. Even currently, it only works for documents that have been blurred without the use of an image.

Unblur Course Hero on an iOS/ Android Device

You can unblur Course Hero on your iOS or Android device for free by using a tweaked app. Before you get the app, you’ll have to change some settings on your device.

On your iPhone, go to the Settings app and tap the option for ‘Battery’.

Then, make sure that ‘Low Power Mode’ is turned off.

Now, go to the ‘General’ settings.

Tap the option for ‘Background App Refresh’.

You’ll see another option for ‘Background App Refresh’ in this menu; tap on it.

Then, make sure that the option ‘Wi-Fi & Mobile Data’ is selected. If it isn’t, tap on it to select it.

If you’re using an Android device, do the same for it, i.e., go to your device settings and make sure that the option for Battery Saver is not under the battery settings. Then, if your phone has the ‘Adaptive Battery’ setting, make sure it’s turned off too. If it doesn’t have it, there’s nothing for you to worry about.

Now that you have the settings in place, it’s time to get the app. As it is a tweaked app, it isn’t available on the App Store or Play Store. Open the browser on your phone and go to the website ‘ojapp.vip’

OJ Apps will open in your browser. Go to the search bar.

Search for ‘Course Hero++’ and tap the ‘Get’ button.

Then, tap the rectangular box with the arrow coming out of it at the bottom of the screen as instructed on the screen.

And finally, tap ‘Add to Home Screen’.

Give the app a suitable name, and tap the ‘Add’ button on the upper-right corner.

The app will appear on your Home screen. Open it and follow the instructions on the screen to complete the download. Once you do that, you’ll see that the tweaked Course Hero app is just the same as the Course Hero app, except for the part that the subscription literally costs you $0.00. And when you tap the purchase button, premier membership will be unlocked for free and you’ll be able to use it with all the benefits that come with it. While using this method, remember that it falls under a morally and possibly, legally gray area.


So, there you have it – several ways you can unblur Course Hero documents for your homework help. While using Course Hero, it’s best to remember that you cannot use exact answers for essays or literature; it’ll be considered plagiarism. You can, although, use the answers for mathematics and other stuff.
