3+ Free Language Learning Platforms

Duolingo's free plan is unlimited and includes its full lesson set, though a paid Duolingo Plus plan at $6.99 a month removes ads. Memrise offers a free tier and a Pro plan at $9.99 a month, with the AI speaking coach sitting behind the paid plan. Busuu has a free tier but lists its Premium plan as contact-sales only, so you cannot see that price without reaching out. Babbel's free option covers only a handful of lessons; the full subscription price is hidden until you create an account. If seeing the price before signing up matters to you, Duolingo and Memrise are the straightforward choices.

Rosetta Stone uses its own speech recognition to give instant feedback on how closely your sounds match a native speaker. Mondly also uses voice recognition and adds real conversation exercises. Memrise takes a different approach: an AI coach listens and responds in a low-pressure setting, with no human on the other end. LingoLooper puts you in a conversation with a 3D avatar across different virtual settings. Its price is not shown on its website and must be found inside the app. Rosetta Stone is the only tool here that pairs speech recognition with live coaching from a real person.

Showing you a word again just before you are likely to forget it is more productive than reviewing everything at once. Duolingo, Memrise, LingQ, and Mondly all use this method. LingQ pairs it with content you import yourself, such as articles or podcasts, and tracks every word you have seen. Mondly builds it into daily lessons. Rosetta Stone, Busuu, and Babbel do not list this method among their features. If that approach is central to how you study, the four tools above are the ones to look at.
