Does Duolingo Have Thai?

No. Duolingo has no Thai course for English speakers — checked against Duolingo's own course directory in July 2026. And the gap matters, because Thai is exactly the kind of language you can't absorb from tap-the-word-tiles anyway: มา (maa, mid tone) is "come", ม้า (máa, high tone) is "horse", หมา (mǎa, rising tone) is "dog" — one romanized syllable, three unrelated words, separated only by pitch. The only Thai on the platform runs in reverse: Thai speakers can use Duolingo to learn English, Japanese, and a handful of other languages. If you search "Thai" in the app as an English speaker, you'll find nothing to enrol in.

So this page does two things: explains why the world's biggest language app skips Thai, and gives you honest alternatives that fit how a Duolingo learner actually likes to study.

Why Duolingo doesn't teach Thai

The practical reason is pipeline economics. Duolingo's smaller-language courses historically came from its volunteer Incubator, which the company shut down in 2021 to focus staff resources on its highest-traffic courses. Since then, expansion has meant scaling the big languages to more audiences — its April 2025 announcement of 148 new courses was about teaching its seven most popular languages (Spanish, French, Japanese, Mandarin and friends) from more interface languages, including Thai. Good news if you're a Thai speaker learning Japanese; nothing at all if you're an English speaker learning Thai.

The deeper reason is that Thai is an awkward fit for Duolingo's format. The core Duolingo exercise — read a sentence, tap the translation tiles — assumes the writing system is a solved problem and that meaning lives in word choice. Thai breaks both assumptions. The script has 44 consonants, vowels that attach on four sides of a consonant, and consonant-class rules that determine tone. And the tones aren't decoration: as with มา/ม้า/หมา above, pitch is meaning. A course that let you pattern-match tiles without hearing and producing tones would produce learners who can "finish the tree" yet be genuinely unintelligible — the format would need rebuilding, not translating, and Duolingo has visibly chosen not to make that investment.

What a Duolingo-style learner actually needs for Thai

If Duolingo is how you like to learn, you probably want four things: bite-size daily sessions, a streak that keeps you honest, a game-like feel, and zero lesson-planning on your part. Keep all four — they're genuinely good habits. For Thai, add the three things no app should let you skip:

1. Native audio on everything. Tones are learned by ear first. Synthesised or missing audio is how learners end up ordering a horse.
2. Explicit tones, visible on the page. You shouldn't have to guess pitch from context. Tone marks — or better, tone colour-coding — turn an invisible feature into something you can see before you say it (here's why tone-marked romanization beats the official system for learners).
3. Real spaced repetition. Thai vocabulary shares almost no roots with English, so forgetting is brutal. A scheduler built on the forgetting curve — like FSRS — is the difference between 90% retention and re-learning the same 50 words all year.

The alternatives, honestly

We compared the full field — Ling, ThaiPod101, Pimsleur, Drops, Mondly, Speekeo and our own app — with verified 2026 pricing in our honest guide to the best apps to learn Thai. The short version, matched to a Duolingo-style learner:

• Ling ($16.99/mo or $89.99/yr) is the closest thing to "Duolingo, but with Thai": a gamified lesson tree, chatbot dialogues, and proper Thai script practice. Its review system is shallower than a true SRS, but the curriculum is the broadest in this style.
• Speekeo (free, no ads) is a speaking-only sprint built around spaced repetition — a genuinely great zero-cost start, with one big caveat: it's Latin-alphabet only, so you'll never see actual Thai script.
• ThaiPod101 ($8–$47/mo by tier) is a podcast-style lesson library rather than a game — enormous content depth, dated tooling.
• Pimsleur ($19.95/mo) is superb ear-first training but its Thai course stops at Level 1 — about a month of material.

If you liked Duolingo's habit, but want real Thai

EffortlessThai — full disclosure, that's us — is built for exactly this hand-off: the daily-reps-and-streaks habit you already have, pointed at real Thai instead of word tiles. Every card shows native Thai script with each syllable colour-coded by tone, plays native-speaker audio, and is scheduled by FSRS, the modern spaced-repetition algorithm, so each day's session is short because it's optimally timed. Study decks come ready-made from real phrase guides — the essential Thai phrases, hello, thank you — so, like Duolingo, there's nothing to plan; you open the app and clear your reviews.

The free tier is a real one, not a seven-day countdown: three curated starter decks plus your own deck of up to 10 cards, with script, tones and audio, free indefinitely. If it sticks, the paid plan is from $10/mo billed yearly ($120/yr), or $20 month-to-month — premium pricing, and we're upfront about why: every card carries native audio and per-syllable tone data, and we'd rather do that properly for fewer learners than cheaply for everyone.

Duolingo may add Thai one day. Your streak doesn't have to wait for it.
