Free Thai language learning, built for English speakers.
ThaiLearn is a free web app and reference library for learning Thai. It combines two things that usually live apart: interactive practice — flashcards, audio quizzes, spaced review, and timed challenges across fifteen vocabulary modules — and a written library of in-depth guides covering Thai script, tones, grammar, and the cultural context behind the language.
Everything is free and works without an account. Signing in only adds cross-device progress syncing and streak tracking. The whole app also works offline once loaded, so you can practise on a plane or a train without a connection.
ThaiLearn is written for English speakers approaching Thai from scratch — travellers, expats, people with Thai partners or family, and self-studiers who want to get past phrasebook memorisation and actually read the script.
We assume no prior exposure to tonal languages or non-Latin writing systems. Where a concept has no English equivalent — classifiers, polite particles, the tone rules — our guides explain the underlying logic rather than asking you to memorise lists.
Our guides are researched and written in-house, then checked against standard references before publication. Every Thai word we print is verified for three things: correct spelling in Thai script, correct romanization, and a tone that we can derive from the consonant class, tone mark, and syllable type rather than one we assumed.
We use the Paiboon+ romanization system throughout, including its tone diacritics, and we apply it consistently across the guides, the app, and the audio. Romanization is a learning aid, not a destination — every entry shows the Thai script alongside it, because reading Thai is the actual goal.
When we find an error, we correct it. If you spot something wrong, please tell us — see the contact page. Corrections from readers who know Thai better than we do make the whole library better.
Vocabulary items and guide examples are paired with audio so you can hear the tone rather than infer it from a diacritic. Tones are extremely difficult to learn from text alone — the written system tells you which tone a syllable carries, but only listening teaches your ear to recognise it.
Questions, corrections, and feedback are all welcome at support@thailearn.app, or through our contact page.
