L0 (5 units) is completely free with no time limit or credit card required. L1-L7 require a Pro subscription.

Duolingo doesn't offer Thai as of August 2026. StudyThai was built specifically for Thai — with full reading/writing instruction, tone-level pronunciation scoring, and a 136-unit structured curriculum that no general language platform can match.

With 20-30 minutes daily: L0-L1 in 2-3 weeks (survival Thai), L2 in 2-3 months (reading ability), L3-L4 in 4-6 months (daily conversation). Thai reading is the hardest part — once you're past L2, progress accelerates dramatically.

We strongly recommend learning Thai script (L2). Romanization is unreliable — there's no standard system, and it can't accurately represent Thai tones. Our 30-unit reading curriculum makes Thai script accessible, and it's the single biggest accelerator for long-term learning.

Each card type targets a specific cognitive skill in the learning process. Tone cards train your ear, writing cards teach stroke order, pattern trainers build sentence construction ability, Talk Time practices real conversation. You need different tools for different skills — a flashcard can't teach you to speak.

Yes. StudyThai is available on iOS and Android with full offline support. Your progress syncs across all devices.

Course content is available in 5 languages: Simplified Chinese, Traditional Chinese, English, Japanese, and Korean. The app interface is currently available in English and Simplified Chinese. Thai is taught as the target language in all versions.

Talk Time places you in a structured dialogue scenario based on what you just learned. You speak Thai, the AI responds naturally, and your pronunciation is scored tone-by-tone. The AI adapts difficulty to your level — L1-L4 difficulty guard rails ensure you're challenged but not overwhelmed.

No, and that's by design. Thai has strict learning dependencies — consonant classes before tone rules, tone rules before reading, reading before conversation. Skipping creates gaps that compound into confusion later. The progression is sequential for a reason.

Every word and phrase you learn in a course unit automatically enters your review queue. The system tracks your performance and schedules reviews at optimal intervals — just before you'd forget. This means 10 minutes of review daily is more effective than 2 hours of cramming weekly.

Every 4-5 regular units, a milestone unit reviews everything from that section. After you complete it, an AI generates a personalized learning report analyzing your vocabulary, grammar, pronunciation, and response patterns — with specific recommendations for improvement.

Thai has a different script, 5 tones, and unfamiliar sounds — but its grammar is surprisingly simple (no conjugation, no articles, no plurals). The key is learning in the right order: tones first, then script, then vocabulary and grammar. That's exactly what our 8-level progression is designed to do.
