You may have seen someone’s phone light up with a little green owl saying “practice today,” and that’s Duolingo. It’s arguably the world’s most talked about language learning app and truth be told, there’s a good reason for that.
But what does Duolingo really do? And it is free, right? And how many languages can you learn in it? We’ll answer all that and more in this guide in plain, simple words. No confusing tech talk, just the clear facts you can trust, verified against Duolingo’s own official information.
What Is Duolingo?
Duolingo is a language-learning app that offers interactive lessons designed to help users practice vocabulary, grammar, listening, reading, and speaking skills. To learn a language you download Duolingo onto your smartphone or open Duolingo in a web browser and take lessons that feel like a game. Instead of relying only on textbooks, you answer questions, match words, translate sentences, and listen to short audio exercises in a game-like format.
Luis von Ahn and Severin Hacker started Duolingo. The company is named Duolingo, Inc. Duolingo is a company whose shares are traded on the Nasdaq under the symbol DUOL. Today Duolingo has tens of millions of users each day. Duolingo considers itself a mobile learning platform.
"Is Duolingo for beginners?" Some of the Duolingo courses, such, as Spanish, French and Japanese now have levels that reach advanced proficiency. Duolingo is not limited to basic beginner phrases.
How Does Duolingo Work?
I open Duolingo then I pick a language I want to learn. Duolingo splits the language into parts called lessons. Each lesson focuses on one skill, like ordering food or asking for directions.
Duolingo uses a few smart tricks to keep you coming back every day:
- XP (Experience Points): You earn points for every lesson you finish. This keeps track of your daily progress.
- Streaks: If you practice every single day, your streak count goes up. Miss a day, and it can reset — this is one of the biggest reasons people keep coming back.
- Leagues and Leaderboards: You are put into a group with students every week. Earn experience points and you go up to a better level, like Bronze, Silver or Diamond.
- Friends Streak: You can also maintain a shared Friends Streak with another Duolingo user. This can help both people stay motivated and practice regularly.
And here's something real users notice quickly — Duolingo now uses an "Energy" system on many accounts instead of the older "Hearts" system. Basically, you get a limited number of energy points each day. Every question you answer, right or wrong, uses up a bit of that energy. When Energy runs out, the options available can depend on the account and current Duolingo setup. Paid plans may provide additional benefits, so check Duolingo's current subscription information for the latest details.
Main Features of Duolingo
Duolingo isn't just flashcards. Over the years, it added several tools to make learning feel more complete.
Stories
Short, interactive reading passages in your target language. You read along and answer questions, which helps you understand real sentences, not just single words.
Podcasts and DuoRadio
Audio content designed for learners, where you listen to real conversations at a pace that's easier to follow than native-speed media.
Duolingo Max (AI-Powered Features)
This is Duolingo's premium AI tier, built using OpenAI's technology. It adds two standout tools:
- Roleplay: You practice a real-life situation, like ordering coffee, by chatting with an AI character named Lily.
- Video Call: You can have a live, spoken conversation practice session with an AI character.
A useful note here — as of January 2026, the "Explain My Answer" feature, which used to be exclusive to Max, became free for everyone. So now, Max mainly stands out because of Roleplay and Video Call.
Duolingo English Test (DET)
This is a separate, official English proficiency test many universities accept, as an alternative to older tests. It's taken online, from home, and results usually come back quickly.
Widgets and Reminders
Duolingo has a home screen widget that you can put on your phone. It also sends reminder notifications. This helps you remember to do your lesson. Duolingo also offers widgets and reminder notifications that can help users remember to practice regularly.
How Many Languages Can You Learn on Duolingo?
Duolingo's official announcements have reported more than 40 languages and over 100 courses, although availability can vary by the user's starting language. The exact number of languages you personally see depends on which language you speak because not every course is available from every starting language.
In 2025, Duolingo announced that it had used AI-assisted course creation to expand its language offerings significantly, helping it launch many new courses in a much shorter time than traditional course development. This made languages like Japanese, Korean and Mandarin available to speakers of more languages, than before.
Some of the most popular languages on Duolingo include:
- Spanish
- French
- German
- Italian
- Japanese
- Korean
- Mandarin Chinese
- Portuguese
- English (for non-English speakers)
Since course availability keeps growing, the best way to check exactly which languages you can learn is to open the app, tap the flag icon, and look at "Add a Course."
Is Duolingo Free or Paid?
Both, actually. Duolingo has a genuinely free version that anyone can use without paying a single rupee, dollar, or euro. But it also offers paid plans if you want extra comfort and features.
Free Plan
- Access to Duolingo's core lessons and courses, with some features and usage limits depending on the current plan.
- Ads appear between lessons
- Limited daily "Energy" or "Hearts," so you may hit a wall if you make too many mistakes or do too many lessons in one sitting
Super Duolingo
Super Duolingo removes ads and provides additional benefits such as unlimited Hearts or other premium features, depending on Duolingo's current app setup. It also adds features like personalized practice and mistake review.
Duolingo Max
This includes everything in Super, plus the AI-powered Roleplay and Video Call features described above. It currently supports a limited number of languages, like Spanish and French, rather than every course on the app.
Family Plan
This lets a group of people, usually up to 6 members, share one subscription, which works out cheaper per person than buying individual plans.
Here's something worth being honest about: Duolingo does not publish one fixed global price list on its website. Prices vary based on where you live the device you use deals and sometimes student offers that come up now and then. Rather than giving a number that could be old by the time you see it the best way is to look at the price shown inside your Duolingo app or, on duolingo.com before you sign up.
Getting Duolingo on your device is simple and takes just a couple of minutes.
- On a smartphone open the Google Play Store if using Android or the Apple App Store if using iPhone. Search, for Duolingo. Tap. Get.
- On a computer go to duolingo.com in any web browser. No download is required. You can learn directly through the website.
- Create your Duolingo account. Create an account using one of the sign-in options currently offered by Duolingo.
- Pick your language. Choose the language you want to learn and the language that you already speak fluently.
- Take the placement test if you like. If you already know a bit of the language Duolingo can test your level. Skip you ahead. This lets you avoid starting from zero.
How to Use Duolingo: A Simple Step-by-Step Guide
Once your account is set up, here's how a normal day on Duolingo looks:
- Open the app. Look at your Home screen. You will see your lesson path, arranged like a game map.
- Select the lesson you want to complete. Most lessons take 5 to 10 minutes.
- Answer the questions. These might be matching words typing translations or talking into your microphone.
- Complete the lesson to get XP. This helps your streak grow. Improves your weekly league score.
- Look at your progress. Go to your profile to see how days in a row you have completed lessons, how much XP you have earned and any achievement badges you have gotten.
- Review your areas. Duolingo usually recommends a short practice session, for words or grammar points that you keep making mistakes with.
Honestly, the biggest tip for beginners is this: consistency matters more than long study sessions. Ten minutes daily on Duolingo usually works better than a two-hour session once a week.
