Does Duolingo have Thai?
No. As of 2026 Duolingo does not offer a Thai course for English speakers. If you search the app’s course list, Thai simply is not there.
The only Thai-related content goes in the opposite direction: Duolingo offers courses for Thai speakers who want to learn English and a few other languages. For an English speaker wanting to learn Thai, that does not help.
Will Duolingo add Thai?
It is unlikely in the near term. Duolingo built many of its smaller courses through a volunteer contributor program, and that program has been wound down as the company focuses on aligning existing courses with CEFR levels. With no contributor pipeline and no announcement, a Thai course is not on the horizon.
The best free Duolingo alternative for Thai
If what you liked about Duolingo was the free, gamified, do-a-little-every-day feel, ThaiLanguageSystem.com is the closest free stand-in for Thai. It runs in the browser, needs no account, and turns learning into short flashcard sessions with streak-style progress.
Crucially, it teaches what Duolingo never could here: the Thai script, vocabulary by theme with audio, spaced repetition and hundreds of short reading-and-listening articles.
The verdict
There is no Thai on Duolingo and probably will not be soon. The good news is you do not need to wait: ThaiLanguageSystem.com gives you a free, gamified way to learn Thai — script included — right now.
