Track your students’ progress and grade their responses in our easy-to-use gradebook.

FluentKey Live is an interactive classroom listening game. The teacher displays a video on a projector while students race to answer comprehension questions on their own devices and compete for the highest score.

It's like Kahoot for language learning. But instead of just answering trivia questions, students are also exposed to rich, authentic, and compelling language. Make listening fun and improve students' listening comprehension skills at the same time. Best of all? It's absolutely free!

It's super easy. Choose a video in our library, then click on "Watch Live" in the right panel.

After you pick the quiz you want to use, a 4-digit code will display on the screen. Have students enter the code on their devices to join the game, then press Play to get started!

First, the teacher needs to start the game and display the join code. Students can then join the game from the website on a computer or mobile device, or from the FluentKey app on iOS or Android.

On a computer or mobile browser, students should go to and type in the join code.

Students can also download the free FluentKey Live app from the iOS or Android app store. Just open the app and type in the join code--it's as fast as that.

FluentKey Live is designed to be played in a class setting. Students answer questions on their own devices while the video is displayed on a shared screen. Teachers need a computer or tablet connected to a projector, while students should have either a computer or mobile device.

Please note that FluentKey Live games must be started by the teacher from a computer or tablet (not a smartphone). However, students can play on their phones.

Nope! We already have a library of hundreds of ready-made videos and quizzes including TV shows, movies, music, news, commercials, and more. It's easy to find the right video for your class by filtering for difficulty, category, and themes. Just choose the video you like, and you're ready to go!

(And you can make or customize your own content, if you want. See the answer below.)

Yes! Live is 100% free for all teachers and students.

Whatever your class is learning, we’ve got you covered with authentic, fresh, and compelling content.

Most of our videos already include built-in comprehension quizzes. Assign the quiz to your class with the press of a button! Not only do they get to watch cool videos at home or in class, you can track their understanding afterwards.

Our quizzes are divided into three different types. Computer-graded quizzes include comprehension questions with fixed answers, like multiple choice, matching, and put in order. Written quizzes have questions that require students to produce short answer written responses. Spoken quizzes have questions that ask students to record audio or video responses.

Note: Quizzes with a range of different types of questions are labeled as mixed quizzes.

Absolutely. Spoken quizzes have questions that your students respond to by uploading audio or video recordings in the target language. When creating your own quiz, select “Audio Recording” or "Video Recording" to prompt your students with speaking questions.

Watch this short video tutorial.

Go to the “Classes” tab and copy the “Invite Link” for a class. You can then paste the invite link into an email or LMS (Google Classroom, etc.). When students click the link, they’re automatically directed to make an account and are added to your class.

You can also add students manually to a class by going to the “Students” tab and then clicking the gear icon next to their name. This method is useful if a student already has an account but needs to change classes.

You can manually add or drop students from a class by going to the “Students” tab and then clicking the gear icon next to their name.

Go to the “Classes” tab and click on the gear icon next to a class.

The best way is to send them an invite link directly (see the answer for "How do I add students to a class?"). We highly recommend that students use a Google or Facebook account if they have one.

Yes! Click on your profile picture in the upper right corner of the screen, then click on “Student View.” This will allow you to explore FluentKey just as if you were a student in your own class. Students can easily see their own assignments and classes. However, they don’t have access to the Video Library and can’t upload or edit videos.

When you want to end the preview, click on the “Switch to Teacher View” button in the green banner at the top of the screen.

This isn’t possible yet. They can reset their own password on the log-in screen, or you can email us at and we’ll reset it for you.


After you open up a video, click on “Assign to Class” in the right panel. You can assign a video in two ways: assign to watch and assign with quiz.

When you assign a video to watch, students complete the assignment by watching the entire video from start to finish.

When you assign a video with a quiz, students complete the assignment by watching the video and also answering embedded comprehension questions as they watch.

After you pick one of these two options, another panel will open up. Choose a due date and an assigned class for your video. Then click the save button!

Watch this short video tutorial.

FluentKey Pro subscribers have access to advanced assignment options.

When you create an assignment, you can control how students watch a video and what they can do in the video player. Navigate to the "Advanced" tab in the assignment creation panel for the following options:

•Allow students multiple attempts to answer a question (the default is 1 attempt)
Pause the video when students leave the window or tab (default on)
•Prevent students from skipping ahead in the video (default on)
•Allow students to increase or decrease video speed (default on)
•Allow students to view subtitles (default on)
•Allow students to view the transcript after an assignment has been completed (default on)

Multiple Choice, Matching, Put In Order, and Scramble questions are automatically graded and scored for you.

Short Answer, Video Recording, and Audio Recording questions must be manually graded. Click on a student’s name within an assignment to see and grade their responses.

Yep. Under the “Assignments” tab, click on the rocket icon next to the name of the assignment. This will take you directly to the video you assigned.


Yes! Become a FluentKey Affiliate and earn money just for talking about FluentKey. Here's how it works:

  1. Become an affiliate: Sign up under your Account Page!
  2. Spread the word: Share your affiliate link with other teachers.
  3. Get paid: When a teacher you invite upgrades to FluentKey Pro, you'll be paid 20% of the total purchase price.

Sounds like a great deal, right? Get started here!

Any teacher with a FluentKey account can become an affiliate. Just sign up here!

Our affiliate program works through Stripe Connect, which collects your name, email, phone number, and banking or debit card details. This is the same platform used by companies like Lyft and Kickstarter, and it's totally secure.

Once you become an Affiliate, you are provided with a unique affiliate link you can share with others.

When a user who clicks on your link makes a new FluentKey account, and signs up for Pro, you will receive 20% of the transaction amount.

On the Affiliate Dashboard, you can see how many teachers have 1) clicked your affiliate link, 2) signed up for an account, and 3) upgraded to FluentKey Pro.

The more teachers that click your affiliate link and upgrade to Pro subscriptions, the more you will earn.

For example, let's say 2 teachers click on your link, make accounts, and then subscribe to an annual Pro plan at $9.99 a month. The total transaction amount added together (for both subscriptions) is $239.75 total. You will personally earn 20% of this total amount, or $47.95.

Note: You will only receive money if the teacher accounts associated with you upgrade to a paid Pro subscription. Free trials do not count.

We partner with Stripe Connect to track and collect your affiliate payments.

Once you have some associated teachers who upgraded to Pro, go to the Affiliate Dashboard. You can see your "Pending" and "Available" balances on the Dashboard.

Your "Pending" balance consists of affiliate payments that have been processed through Stripe, but are not yet immediately available.

Your "Available" balance consists of payments that are immediately available. Click on the "Pay out now" button to immediately deposit your available balance into your bank account or your debit card (depending on the information you gave Stripe).
