Thai Tea Suit — Learn Thai

Thai, taught the way field linguists actually learn languages.

Comprehension first. Listening before speaking. No streaks, no guilt, no confetti — just a quiet, expert path from your first word to real fluency, built for people who'll be in Thailand a year or more, not a two-week trip.

THE METHOD • Picture-first lessons — understand before you translate • Tone-colored romanization you can fade out as Thai script takes over • Train your ear: minimal-pair sound drills and a tone lab that scores your pronunciation on-device • Spaced-repetition reviews that come first on heavy days, so memory never silently decays • A placement check that starts you where you actually are

ONE CALM PATH The app always knows your next step. One recommended lesson, your reviews, and nothing shouting at you. A daily practice contract sized to real life — some days that's one review session, and that's enough.

GOES DEEP • A deep everyday-Thai course — hand-finished lessons from your first words to advanced, growing every week • Your own decks for the vocabulary your life actually needs • Conversation scenes, memory palace, and study kits when you want more ways in • Register-aware: polite particles, street Thai, and when to use which

FREE AND PREMIUM The everyday starter lessons are free, and reviews of everything you've learned stay free forever — your memory is never held hostage. Premium opens every lesson in every track, with monthly, yearly, or pay-once lifetime options.

Built in Chiang Mai by a long-term learner, for the next one.
