sabaisabaiLearn Thai, the relaxed way.
sabaisabai is a calm place to actually learn the Thai script: letters, tones, vocabulary, classifiers and real reading. Built around short sessions, hearable letters, and games that make practice stick.
Three things you'll do every day
Short sessions, mixed practice. The app keeps each one a tap away.
Five tones, and a calculator that explains every one.
Pick a class, an ending and a tone mark to see the resulting tone, the contour shape and the rule that produced it. Then drill it with randomized syllables that build a streak.
- ✓Tone overview: five contour cards with native examples you can hear.
- ✓Class-by-class reference matrix: every combination, all in one place.
- ✓Practice mode with streaks and a celebration every five in a row.
Nine ways to practice
Mix it up so practice never feels like homework. Each game targets a different skill: sound recognition, vocabulary recall, class memory, hand-writing, speed. Three start unlocked, the rest open up as you earn XP.
Sabai Bangkok's Adventures.
A side-scrolling platformer that opens onto a Bangkok level map. Lumpini Park is playable today — Wat Arun, Wat Pho and Chatuchak are visible on the map as locked previews. Run, jump, dodge critters and pick up Thai words as you reach the sala.
- ✓Words you collect bank to your vocab on win, plus XP for new ones.
- ✓Pause to adjust sound and volume, or save & quit mid-run.
- ✓Plays right in the browser, no install or plugin.
Two faster ways to grow your vocabulary.
Adding words used to be one form at a time. Now you can let AI complete the entry or paste a whole spreadsheet at once.
AI fill the form
Type just the Thai, English or romanization. Tap AI fill and the rest — pronunciation, category, an example sentence and its translation — gets completed for you. Your typed values are never overwritten.
5 generations per UTC day per learner; the cap is admin-configurable.
Import from Excel
Got a vocab list in a spreadsheet? Drop the .xlsx or .csv into the importer and every row lands in your personal deck. Headers like thai / english / rtgs are detected automatically; duplicates are skipped, and there's a one-click template if you're starting from scratch.
Open the vocab tabYour name, in Thai script.
A small taste of what Thai writing feels like. Type a name, hear it spoken. No signup needed.
Your name in Thai will appear here.
Playful approximation. Real Thai transliteration of foreign names follows tone-mark and consonant-class rules we don't apply here. Use this for fun, not for paperwork.
The world of Sabai & Sabai.
Two durians, both named Sabai. She wears pink glasses and waters her flower garden, he wears blue glasses and never puts a book down. Their everyday moments are written in beginner-level Thai, complete with comprehension questions, so you can read along from day one.

Stories and dialogues highlight the words you know in red. Hover or tap an unknown word to see its romanization and translation, and add it to your vocabulary in one click.
- ✓11 short stories with side-by-side Thai and English.

Tap any consonant, vowel, vocab word, classifier or tone example to hear it spoken in Thai.
Word-level reading help
Words you've learned are highlighted; hover anything else to look it up, or save it to your vocabulary.
Tone calculator & trainer

Mastery & medals
Each letter tracks how often you get it right. Bronze, silver, gold appear as you improve.
