Duolingo Thai: Why There Isn’t One
The short answer is no. Duolingo does not offer a Thai course, it isn’t in beta, and there has never been a public one. If you came here to find out whether you missed it somewhere in the app, you didn’t. Here’s what’s actually known, and what people use instead.
Dublo is a Thai learning app, and Dublo is listed below alongside the others rather than above them. We use no affiliate links, we receive no commission or payment from any product mentioned, and we have no commercial relationship with any of them. Availability and features were checked in July 2026 and products change, so treat each company’s own site as the authority. Prices are deliberately not listed, see the note at the end. All product names and trademarks are the property of their respective owners, and are used here for identification only.
Key facts
- Duolingo does not offer Thai, in any direction, as of July 2026.
- It is not in the incubator or in beta. Duolingo closed its volunteer-run Incubator programme in 2021.
- Tone is not the barrier: Duolingo teaches Mandarin and Vietnamese, both tonal.
- Babbel, Rosetta Stone and Busuu also do not offer Thai. Thai-specialist products and a handful of multi-language platforms do.
The direct answer
There is no Duolingo Thai course. Not for English speakers, not for any other base language, and not hidden behind a setting. Learners searching for one usually find third-party pages that rank for the term without answering it, which is why this page answers it in the first line.
Why there isn’t one
Duolingo has not published a specific explanation for Thai, so anyone claiming to know the internal reason is guessing. What is on the record is the structural change that made new languages far rarer:
Duolingo originally added many languages through its Incubator, a programme in which volunteer bilingual contributors built courses. Duolingo wound the Incubator down in 2021 and moved course creation in-house, stating that it would concentrate on improving its existing courses with professional linguists rather than adding new languages. Thai never had a course completed under the volunteer model, and the in-house model has since prioritised widening the most popular languages to more base languages rather than adding new target languages.
Beyond that, the plausible commercial reading, and it is a reading rather than a fact, is straightforward. Thai has a smaller global learner base than Spanish, French, Japanese or Korean. It also needs specialist production: a non-Latin script, five tones, and audio that has to be checked tone by tone, since tone errors in teaching audio are far more damaging than in a non-tonal language.
What can be ruled out is the assumption people most often make. Tone is not the obstacle in itself, because Duolingo teaches Mandarin Chinese and Vietnamese, both tonal languages with large courses.
Duolingo isn’t the only one
If you widen the search to the other household names, the pattern holds. As of July 2026:
| Platform | Thai? | Note |
|---|---|---|
| Duolingo | No | No public Thai course has existed |
| Babbel | No | Catalogue concentrated on European languages |
| Rosetta Stone | No | Thai not among the languages offered |
| Busuu | No | Published catalogue of around 14 languages excludes Thai |
| Pimsleur | Yes | Audio course format |
| Mondly | Yes | Gamified app format |
Which is the practical takeaway: learning Thai means using either a Thai-specialist product or one of the smaller number of multi-language platforms that cover it.
What people use instead
The realistic options, described in full in our objective comparison of Thai apps:
- Closest to the Duolingo format, short gamified lessons with streaks and daily targets: Ling and Mondly. Dublo also uses short daily units, though it follows one continuous journey rather than a skill tree.
- If you want depth and a large library: ThaiPod101, a Thai-specialist catalogue of audio and video lessons.
- If you learn by listening: Pimsleur for spoken courses, Glossika once you are past the beginner stage.
- If you want a person correcting you: tutor marketplaces such as italki and Preply, or an in-person school.
- For free reference: thai-language.com.
If it was specifically Duolingo’s format you liked
It’s worth separating what you liked, because different products replicate different parts of it. The daily streak and short-session habit is the part most Thai apps reproduce. The gamified skill tree is reproduced by Ling and Mondly. The free tier is the hardest to replace: Duolingo’s advertising-supported free model is unusual, and Thai products generally use free trials or a limited number of free lessons instead, because the Thai learner market is too small to support the same economics.
Will Duolingo add Thai?
There is no announcement, no beta and no publicly stated plan. Course additions since the Incubator closed have not included Thai. Treat any page promising a launch date with scepticism, and note that this page states a date it was checked precisely because claims like this expire.

Dublo, stated plainly
Dublo is the product we make: a Thai-only spoken course in short daily units, listed alongside the alternatives above rather than above them. Audio is text-to-speech rather than native-speaker recordings. Your first payment is refundable for 14 days.
Frequently asked questions
Is Thai on Duolingo?
No. As of July 2026 Duolingo does not offer a Thai course in any direction, it is not in beta, and no public Duolingo Thai course has ever existed.
Why doesn't Duolingo have Thai?
Duolingo has not published a reason specific to Thai. What is on the record is that it closed its volunteer-run Incubator programme in 2021 and moved course development in-house, focusing on improving existing courses rather than adding new languages. Thai's smaller learner base and the specialist production a tonal, non-Latin-script language requires are plausible commercial factors, but that is an inference rather than a statement from the company.
Is Thai too tonal for Duolingo's format?
Tone alone cannot be the explanation, because Duolingo teaches Mandarin Chinese and Vietnamese, both tonal languages. The gamified translation-drill format does handle pronunciation weakly in any language, which matters more in a tonal one, but that applies to its existing tonal courses too.
What is the closest thing to Duolingo for Thai?
In format, Ling and Mondly are the closest, both use short gamified lessons with daily targets. For a Thai-specialist alternative with a large lesson library, ThaiPod101. For audio-led study, Pimsleur. Dublo, which we make, also uses short daily units but follows a single continuous journey rather than a skill tree.
Will Duolingo add a Thai course?
There is no announcement, beta or publicly stated plan as of July 2026. Course additions since the Incubator closed in 2021 have not included Thai.
