Beyond Duolingo: language learning tools for serious learners
Duolingo is exceptional at one thing: making language learning feel like a game you want to open every day. The streak mechanic, the cheerful UI, the quick dopamine hit of completing a lesson — it's genuinely well-designed for habit formation.
It's less good at producing people who can actually speak a language. If you've been on Duolingo for six months and still can't hold a conversation, you're not doing it wrong. The app has a ceiling.
Preply is for people who've hit that ceiling.
The Duolingo ceiling
Duolingo teaches vocabulary and basic grammar through recognition and pattern matching. You'll learn to read simple sentences and pass beginner exercises. What it doesn't teach well:
- Spontaneous speaking. The app gives you controlled prompts. Conversation is unpredictable.
- Listening comprehension at native speed. Duolingo's audio is slow and careful. Real speakers aren't.
- Cultural context. The difference between formal and informal register, regional expressions, when to use which construction — that's almost entirely absent.
- Correcting your actual errors. If you're making the same grammar mistake repeatedly, Duolingo can't identify it as a pattern.
The result: many Duolingo users plateau at A2 (elementary) level and stay there indefinitely.
Preply — live tutors for real progress
Preply connects you with professional and community language tutors for live, one-on-one video lessons. It's a fundamentally different approach: instead of completing exercises, you're having actual conversations with a human who can correct you in real time.
What makes it work:
- Over 40,000 tutors across 50+ languages, with profiles, ratings, and trial lesson options
- Lessons scheduled around your availability — 30-minute conversation practice or 60-minute structured lessons
- Tutors specializing in specific goals: business language, travel prep, exam preparation (IELTS, DELF, DELE)
- The immediate feedback loop of a real conversation accelerates progress in ways no app can replicate
Honest weaknesses:
- It costs real money. Tutors range from $5 to $80+ per hour depending on credentials and language. Budget $50–$150/month for 2–3 sessions per week.
- Quality varies by tutor. Reading reviews and using trial lessons matters.
- You still need to do work outside sessions to retain vocabulary.
How to combine them
Duolingo and Preply aren't mutually exclusive. A practical approach:
- Use Duolingo for daily vocabulary review and keeping the language active in your brain between sessions.
- Use Preply for weekly conversation practice where a tutor pushes you past the patterns Duolingo has drilled in.
This combination is what most intermediate learners find effective: spaced repetition for vocabulary, live conversation for fluency.
Who should make the switch
Preply is the right call if:
- You're past beginner level and want to actually speak the language
- You have a specific goal: business meetings, an upcoming trip, an exam
- You've plateaued on apps and need accountability
- You want feedback, not just exposure
Duolingo is still worth keeping if you want daily vocabulary maintenance or are just getting started and need the habit to form first.
The bottom line
Duolingo is the best free tool for building a language habit. Preply is the best tool for building language ability. After a certain point, those are different things.
