Most Thai apps sound wrong. Ours doesn't.
A native-trained Thai voice on every word. 2297 hand-picked words, 262 phrases, eight grammar lessons, and the situations you'll actually be in — ordering food, taking a taxi, checking into a hotel. Free to start.
Built in Bangkok for learners tired of apps that don't sound Thai.

Most Thai words are made of other Thai words.
ThaiDai shows you the seams. A learner who knows น้ำ (water) and แข็ง (hard) can read น้ำแข็ง (ice) off the script the first time. We capture that structure in the schema and surface it on every card. Once you see the pattern, the lexicon stops being a memorisation pile and starts being a Lego set.
Pick how you learn.
There's no single right way in. Follow the journey for a guided route through real situations, or drop into any mode on its own — they all draw on the same corpus.

Study a thing first. Practise it after.
Most apps drop you straight into a quiz. You're guessing at words you've never met, tapping wrong, losing streak hearts, feeling stupid. We split it: read, listen, browse — then prove what you remember. No XP for studying. All XP for practice. The streak rewards both.
Why we built it this way →Read, listen, browse.
Cycle through dialogue lines, frame substitutions, scenario turns. Tap the audio. No pressure to be right.

Thai sounds like Thai.
Most Thai apps ship audio that sounds like an English speaker reading romanisation. The vowel lengths drift, the syllable-final consonants stay open. We tested every model. Only one closed ส to /t/, kept vowel lengths intact, and sounded like a real person.
Native-trained Thai voice on every word
Audio for every word and phrase in the corpus. Pre-cached for the free tier; generated and cached on first request for Pro.
Compositional pedagogy
Phrases unlock once you have learned the parts. The deck shows you the etymology — which words combined to make this one — so each new entry leans on what you already know.
Streaks and six levels
Six tiers from Novice to Native-adjacent. The streak is the teacher.
Put ThaiDai on your home screen.
It installs straight from the browser. No app store, nothing to update by hand, and the audio you practise keeps working on a weak signal.
In Chrome: open the browser menu and choose Install app. On iPhone: Share, then Add to Home Screen.
