Read full descriptionHide full description
StudyThai.ai teaches Thai to English and Chinese speakers. 136 units and thousands of exercises take you from your first sound to real conversation. STRUCTURED COURSES (L0-L7) 8 levels, 136 units, 672 sub-lessons, and over 10,000 exercises. From the alphabet to fluency, the path is already mapped out — no guessing what to study next. Each lesson includes vocabulary cards with 3D illustrations, IPA pronunciation, example sentences, and grammar tips, with a quiz closing every unit. 17 EXERCISE TYPES Far more than multiple choice. Listen-and-choose, picture matching, sentence cloze, Thai script assembly, tone identification, syllable segmentation, handwriting practice, and speaking repetition. The two hardest parts of Thai — five tones and text written without spaces between words — each get their own dedicated drill. MASTER THAI PRONUNCIATION 44 consonants, 32 vowels, 5 tones, all organized in an interactive grammar center. Use the tone calculator, IPA transcriber, and pronunciation comparison tools to nail every sound. Native-quality audio for every consonant and vowel. AI THAI TUTOR Open the chat and type — English, Chinese, or even broken Thai. Every Thai reply arrives with translation, native audio playback, and tappable vocabulary cards on the words you are learning. Type "let me practice ordering coffee" and the AI starts the scene in Thai. Want something specific, like a hospital check-in or a rent negotiation? Just ask and it builds the scenario. Send a photo and the AI describes what is in front of you in Thai. Pick a style — Free Chat, Learning, or Teaching — to tune how much help you get. SNAP & LEARN See something you don't know the Thai word for? Snap a photo. The app recognizes the object and returns the Thai word, IPA, translation, example sentences, and cultural notes in seconds. Every capture is saved to your album, auto-organized by category. 100,000-WORD DICTIONARY Look up any Thai word for accurate meanings, multiple senses, IPA, audio, and natural example sentences. Over 100,000 Thai words, curated from a learner's perspective. LEARN BY PLAYING Five free games: Syllable Match, Consonant 2048, Word Pair Match, Word Triple Match, and Memory Match. Reinforce what you've learned without the pressure of a test. SMART VOCABULARY Spaced repetition adapts to you — words you struggle with come back more often, words you know fade into review. The wordbook is free for everyone, with 15 new words per day. Pro unlocks unlimited collection, CEFR-level wordbooks, and six topic collections: food, travel, medical, business, education, and nature. 8 THAI FONTS Switch how Thai script renders across the app, from standard text faces to display styles. Pro unlocks six additional typefaces for more comfortable long-form reading. BILINGUAL SUPPORT Full English and Chinese interface, with side-by-side translations, cross-language grammar notes, and cultural context. FREE TO START 15 units are completely free: all five Level 0 units, four in Level 1, and the first unit of every level from Level 2 to Level 7. The wordbook, the dictionary, and all five games are free for everyone. Upgrade to Pro for all 136 units, unlimited AI tutor conversations, Pro wordbooks, and display fonts.

Verdict
The clearest difference is update cadence: Sawasdee at weekly against StudyThai.ai's fortnightly. StudyThai.ai's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
