Duolingo has helped millions of people start their language learning journey, and we have deep respect for what they've accomplished.
But we believed there was a different approach to language learning—one focused on reading, listening, and engaging with real content rather than completing exercises—so we built Bubblegum.
This post compares both approaches so you can understand the key differences and decide what works best for your learning style.
Duolingo vs Bubblegum Philosophies
Duolingo: Engagement First - Duolingo prioritizes keeping learners engaged through gamification, streaks, and gentle difficulty curves. Their approach focuses on maximum retention rather than maximum learning efficiency.
Bubblegum: Learners First - We're FOR language learners, BY language learners™. We believe adult learners can handle meaningful challenges and find deep satisfaction in reaching a flow state while engaging with real content.
Our philosophy: Focus on learning, and engagement follows naturally. The most sustainable engagement comes from genuine progress—understanding your first joke, reading a challenging news article, or having a real conversation in the language you're learning.
Philosophical Differences: The Full Details
If you want an even deeper understanding of the fundamental philosophical differences between Duolingo and Bubblegum, read this section.
Duolingo: Engagement First
Duolingo's founder Luis von Ahn has been remarkably candid about their approach: he doesn't enjoy learning languages, and neither did any of Duolingo's early team. This shaped their focus on making language learning engaging enough for people who don't naturally love the process.
Engagement Over Education
Duolingo's founder Luis von Ahn has been transparent about their approach: when engagement and learning outcomes conflict, they choose engagement.
According to an interview with the founder, their reasoning is practical—you can't teach someone who leaves the app. They prefer teaching material slowly with constant dopamine hits rather than allowing the natural challenges that come with language learning. They worry that the tiniest frustrations might send learners to other apps like TikTok.
What This Means for Their Product
This philosophy explains Duolingo's gamification, streak systems, and gentle difficulty curves. It's designed for maximum retention rather than maximum learning efficiency. This approach worked well for getting millions of people started and building habits, though many serious learners eventually seek more challenging and authentic content.
There's genuine value in Duolingo's approach—making language learning feel accessible and non-intimidating helps millions of people get started. Their gamification approach can indeed work for building initial habits and extrinsic motivation.
Bubblegum: Learners First
At Bubblegum, we come from a different starting point. We're FOR language learners, BY language learners™. We have developed a love for learning a language and believe that you, too, can experience the joy of making real progress.
We know that we'll never be the biggest language learning app, so that's why we're trying to make the BEST one.
Our team understands that language learning naturally involves productive struggle: ups and downs, moments of confusion, and breakthroughs that come after sustained and focused effort. These challenges make the journey rewarding and meaningful!
We also reject the idea that language learning apps need to operate in the attention economy, fighting for attention rather than creating valuable learning tools. That's why we commit to never adding ads to our app.
Adult language learners don't need constant stimulation or dopamine hits to stay engaged.
Instead, they can find deep value and meaning in reaching a flow state—that immersive experience you get when reading a captivating book or watching an engaging movie.
The Duolingo Approach: Bite-Sized Interactive Exercises
Duolingo has become synonymous with language learning through its distinctive approach of breaking language into small, interactive exercises. Let's examine the core components of their methodology:
Duolingo-Style Exercise Examples
🔄 Word Arrangement Exercise
Arrange these words to match: "I want to drink water"
Available words:
Your sentence:
⚠️ The Problem: This exercise forces you to think in English first ("I want to drink water"), then translate to your new language. You're not learning to think directly in the target language—you're just memorizing word-for-word translations.
Other types of exercises on Duolingo:
- Mark the correct meaning: Multiple choice questions testing translation accuracy
- Picture flashcard matching: Visual association between words and images
- Tap the pairs: Matching exercises connecting new language with native language
- Speak this sentence: Pronunciation practice with speech recognition
- Type what you hear: Transcription exercises testing listening skills
- Read and respond: Reading comprehension with highlighted vocabulary
- Select the missing word: Context-based vocabulary selection
- What do you hear?: Audio comprehension with multiple choice answers
Although it is exciting to get the exercises correct, each one encourages you to think in English first, then translate to your new language. We've all been there—understanding every word in an exercise but freezing up in real conversation. That's because these exercises train a different skill than natural communication.
See our full breakdown of why translation exercises slow you down and why to avoid apps that tell you that you can learn a language in five minutes a day.
The Bubblegum Approach: Take What Really Works and Make It Better
Instead of breaking language into mini exercises, we give you real content with all the support you need:
- Instant vocab lookups that understand context
- Grammar and cultural explanations when you need it
- Your interests first: Love food? Read about new foods and cultural practices surrounding food. Learning for work? Dive into dialogues or news in your industry
- 6 levels of difficulty with AI-powered adjustments to create the optimal ratio of known and unknown words that keeps you in that sweet spot—challenged but not overwhelmed
🚀 Coming Soon: We're starting with Korean and will add Japanese, Spanish, Chinese, and more languages once we perfect the Korean experience.
Choose Your Level
Why We Built Bubblegum
Apps That Showed Us What Was Possible
We found incredible inspiration in apps that moved beyond the traditional approach of finding content online, translating it manually, looking up words in separate dictionaries, and searching for grammar explanations. Each one solved real problems we'd experienced as language learners:
DuChinese (Mandarin): Seamless hover translations that don't break your reading flow—you could read a story and instantly understand new words without losing your place.
Satori Reader (Japanese): Engaging stories with professional voice recordings and grammar explanations perfectly tailored to the learner's level.
LingQ: Brilliant vocabulary tracking system where seeing your known words highlighted gives such a sense of progress. But looking for content suited to our exact level felt like finding a needle in a haystack.
ChatGPT and other AI tools: Instant, context-aware explanations for confusing sentences or grammar patterns. But we thought we could make it even more seamless to generate, read, and listen to content made specifically for language learners.
The Gap We Saw
While each of these apps excelled in their domain, none offered the comprehensive experience we were looking for. The language-specific ones (DuChinese, Satori Reader) had incredible depth and tailored tools, but only for one language. LingQ supports many languages, but without the specialized tools that make learning any particular language truly effective.
That's why we built Bubblegum—to bring that same level of thoughtful, language-specific design to one language at a time (starting with Korean), combining the best insights from each of these platforms.
We chose to focus deeply on only one language that we knew needed more love (and that we're all actively learning ourselves) because we believe in getting it right BEFORE expanding.
All the tools you need in one place, designed specifically for language learners.
How Learning Actually Happens
Exercise-Based Learning Downsides
Typically, micro-learning exercises train your brain to think... Korean word → think in English → English translation → ✓ Correct!
Many people find that this translation process works well for exercises, but real conversations happen much faster. When someone asks you a question, there's often not enough time to mentally translate each word before responding naturally.
What Actually Works
The linguist Stephen Krashen discovered something we all know intuitively: you learn language best when you're so engaged you forget you're learning. People who binge-watch shows in their new language often pick it up faster than textbook grinders because they're getting massive amounts of comprehensible input while enjoying themselves.
The difference: Instead of learning the word for "eat" through translation exercises, you read a story about friends sharing a meal. You discover how it's used in real social situations—the cultural nuances, expressions of hospitality, the way language connects to relationships and traditions. Words aren't just translations—they're wrapped up in culture, context, and human connection.
When Each Approach Works Best
Duolingo works well for:
- Absolute beginners building confidence with basic vocabulary
- Quick refreshers when returning to a language after a break
- Habit building for people establishing a learning routine
Bubblegum works well for:
- Learners ready for real content who want to move beyond basic exercises
- People who want to understand culture and context, not just vocabulary
- Anyone seeking sustainable engagement through genuine progress rather than streaks
Exercise-based learning works best as a foundation. Once you're comfortable with basics, reading real content accelerates your progress significantly.
The Bottom Line
Both approaches have value. Duolingo excels at building habits and teaching basics through gamified exercises. Bubblegum focuses on reading real content with integrated support—hover translations, AI explanations, vocabulary tracking, and follow-along audio, all in one place.
If you're ready to move beyond exercises and into real Korean content—stories that make you laugh, articles that teach you something new, conversations that prepare you for real-world interactions—Bubblegum combines the best tools from across the language learning ecosystem into one seamless experience.
