Sapere.ai: The Best Alternative to Duolingo and Babbel

Why so many learners are looking for an alternative

Our teachers hear the same frustration from language learners time and time again: "I practice every day, but I still can't speak the language." Duolingo and Babbel have made language learning accessible to millions, but their fixed, one-size-fits-all approach often leaves learners feeling stuck, unable to turn what they've learned into real-life conversations.

Sapere.ai takes a different approach: a learning path personalized by artificial intelligence, which you can also use together with a teacher. Here's why we believe it's the best alternative for anyone who truly wants to progress.

The 4 most common frustrations among learners

"I understand the exercises, but I can't speak"

This is the number one complaint. Apps mostly train you to recognize and match words; they rarely make you produce spontaneous sentences. Yet speaking means building your own sentences, under pressure, in front of someone. That takes practice, ideally with a real conversation partner.

"Am I learning, or just collecting points?"

Streaks, trophies, leaderboards: gamification motivates, but it measures consistency, not mastery. A 300-day streak says nothing about your ability to hold a ten-minute conversation.

"I understand the app, but not native speakers"

App voices speak slowly, articulate perfectly and use predictable sentences. Real life means accents, fast speech and slang. Without exposure to authentic language, the gap remains huge.

"How do I keep going without getting discouraged?"

Motivation drops when you no longer see the link between the lessons and your own life. Learning "the apple is red" won't help you succeed in Monday's meeting. Relevant content and a regular appointment with someone are the two best antidotes.

Sapere.ai: a learning path built for you, by AI

"Why don't the exercises match my needs?" The answer is simple: they weren't designed for you.

Sapere.ai starts from the learner, not from a curriculum. The platform uses AI to build a path that matches your goals, your field and your interests.

• Personalized vocabulary. You learn the vocabulary of your profession or discipline: legal, medical, technical or business terms.
• Tailored lesson plans. Each path is aligned with a specific goal: acing a job interview, presenting in a meeting, preparing for an exam.
• Dynamically generated material. Texts and exercises are created based on your profile, rather than pulled from a fixed bank.

The result: every minute you spend on the platform directly serves how you actually use the language.

This is especially true in a professional context. "How do I learn the vocabulary of my job?" is a question no mainstream app answers. For a company training its teams, Sapere.ai makes it possible to target the language of its industry directly: the language of clients, contracts and meetings.

The key advantage: learning together with a teacher

"Do I really need a teacher?" The question comes up often. Our answer: it's not one or the other, it's one with the other.

Duolingo and Babbel are designed for self-study. Sapere.ai works just as well for independent learning as for guided learning.

Working as a duo, each does what it does best:

• The AI generates the material, adapts the exercises and provides practice between sessions.
• The teacher corrects nuances, explains cultural context, keeps the learner motivated and gets them talking.

For teachers, it also saves time: fewer hours preparing material, more time for conversation. AI doesn't replace the teacher; it makes them more effective.

Is conversation with an AI enough?

Practicing with an AI is excellent training: available around the clock, patient and judgment-free. It's ideal for daring to say your first sentences. But it doesn't replace a human conversation partner, who reacts with emotion, accent, the unexpected and culture. The AI + teacher duo combines the sheer volume of practice of one with the human richness of the other.
