🇹🇭 The best websites for learning Thai

A collaborative, Creative Commons-licensed corpus you can search for real usage of a word or download in bulk to build your own decks. It is the raw material behind Clozemaster and countless Anki decks rather than a study tool in itself. Sentences are contributed by volunteers, so quality and naturalness vary — prefer sentences from native contributors and cross-check anything surprising.

A long-running community reference with a large Thai–English dictionary, audio, per-word tone and phonemic analysis, sample sentences, grammar lessons and archived forum discussions that answer questions nothing else does. It is the site experienced learners keep open in a tab. The design is unapologetically from an earlier internet era and the site serves over plain HTTP, so expect a browser warning if you force HTTPS.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

Type a word or phrase and it plays back real YouTube clips of people saying it in context, across 25 languages plus sign languages, so you get natural intonation and regional variation rather than an isolated dictionary recording. Free, donation-supported, no account needed. Complements Forvo: Forvo for single words, YouGlish for phrases and prosody.

A browser extension plus web reader covering 100+ languages: click a word or drag across a phrase, get an inline translation, and it becomes a flashcard automatically. The free tier gives unlimited single-word translations but caps phrases and AI explanations at 10 a day; Premium is $6/month. Simpler and cheaper than LingQ or Migaku if all you want is frictionless reading of articles and ebooks.

A detailed staged roadmap for acquiring a language through massive comprehensible input — what to do at each stage, when to start output, how to mine sentences — with a free tracker, starter courses and an active Discord. The roadmap and community are free; vocabulary decks, advanced courses and coaching are paid. It is opinionated to the point of dogma about avoiding early output and translation, so take the framework and ignore the purity rules if they do not fit your goals.

Grace publishes a free ten-day absolute-beginner mini course, a beginner podcast, subtitled YouTube lessons and a free phrase ebook, then sells structured courses covering beginner-to-conversational Thai, practical reading and an advanced tier, plus a graded reader and vocabulary apps. The free layer is substantial enough to be worth using on its own. Materials are spread across several platforms, so it takes a moment to work out what belongs to what.

Khru Nan is a Thai university lecturer with a PhD in linguistics, and it shows in how carefully she handles tones, vowel length and the sounds learners systematically mishear. The podcast is free on Spotify, Apple Podcasts and YouTube, with transcripts and Quizlet flashcard sets on the site; extra episodes sit behind Patreon. Episodes are short and conversational rather than a structured syllabus, so use it alongside a course.

Brett Whiteside's course drills the writing system and tone rules first, then builds spoken Thai on top, which fixes the classic expat problem of years of transliterated Thai that natives struggle to understand. Five lessons are free by email, so you can judge the teaching style before paying for the full Inner Circle program. It is one of the pricier self-study options and the sales pages are heavy on testimonials — the underlying pedagogy, not the marketing, is the reason to consider it.
