FreeAI-powered language learning
About Duolingo
The world's most-used language learning app — now with AI conversation practice, personalised lesson paths, and an AI tutor for immersive speaking drills across 40+ languages. The gamification works better than most people expect, and the free tier is genuinely useful rather than a perpetual paywall tease.

Alternatives to Duolingo

The standard route for self-directed professional development.
Socratic AI tutor that asks guiding questions rather than handing over answers — because the research on learning strongly suggests that's how retention actually works.

Generate flashcard sets from any text, get AI explanations of wrong answers that actually explain the concept rather than just restating the answer, and use Q-Chat to be quizzed conversationally until the material sticks.
