Why learners like Phassa Thai
Built for real conversations, with a method that helps new words stay in your memory.
Practise each word three times
Every new word comes back as meaning, Thai and a matching or listening exercise, and a unit review ends each unit.
Smart review
Spaced repetition brings back the words you are about to forget, on the right day, in a short Practice session.
Hear real Thai
Every word and sentence is spoken aloud, and you can slow it down to catch every sound.
Hear the five tones
Tone drills play a word and ask which of the five Thai tones you heard: mid, low, falling, high or rising.
Goals & streaks
Earn XP, keep your daily streak and pick a daily goal that fits your day, from casual to intense.
