Learn Thai with Surang

I'm an AI language teacher built specifically for Thai. My lessons adapt to your skill level and cater to your specific goals — whether that's a two-week vacation, or fluency for a lifetime.

Why is Thai so hard?

Most language apps treat every language the same way: drill vocabulary, gamify the streak, call it teaching. That works for languages where vocabulary is the main lift. Thai isn't one of those languages.

Tones change meaning.

Five tones — mid, low, falling, high, rising. The same syllable can mean horse, come, scold, dog, or mother depending on pitch.

The script encodes information.

Thai script carries tonal and phonemic information that romanization loses. Skip the script and you build on an unstable foundation.

Classifiers structure how you count.

Every countable noun has a conventional classifier — "a sheet of paper" applied to everything. Not optional. Not learnable from flashcards.

Politeness register isn't optional.

ครับ and ค่ะ aren't decorations — they signal respect, gender, and social context. Native speakers notice their absence immediately.

Why use an AI teacher?

Surang does what no human teacher can.

She tracks what you've learned.

Words you study together, she remembers. Words that are fading come back at the right moment. Words you've mastered stay in the background. No human tutor tracks 200 words across 60 lessons.

She builds your lesson live.

Not a rotation of pre-made content. Every lesson is generated for you, based on what your brain needs to practice.

She's there at 3am.

No off days.
No cancelled lessons.
When you're ready, she's ready.

How I teach

See it. Hear it. Say it.

Real language learning isn't one channel — it's three. You have to recognize what you're looking at, hear how it sounds, and produce it with your own voice. Most apps pick one and call it teaching. Every word I introduce hits all three.

See

Thai script, always visible

Romanization shows you how to pronounce it. Script shows you what's actually there. Tone marks, vowel length, consonant class — all encoded in the writing.

Hear

Audio on every word

Five Thai tones, and they change meaning. Hearing the difference is the only way to learn it. I play every word, every example, every time.

Say

Speak it aloud

Even without speech recognition, saying it activates muscle memory that recognition alone can't reach. After key moments, I prompt: "Now you try — say it aloud."

Fluency Level

Market Regular

Honest measurement

See real progress — not points.

No XP, no leagues, no streaks-as-progress — just real skill, measured the way languages actually are.

A real benchmark. Your overall level on the CEFR scale — the international A1–C2 standard for language proficiency.
Five skills beneath it. Tones, listening, vocabulary, reading and grammar — each measured on its own.
No fake confidence. Unproven skills show as "needs evidence," never inflated.

Why I built Surang

I fell for Thailand as a traveler — a few trips that turned into "I have to live here someday." So I tried to learn Thai, but the competitors either didn't offer it, felt confusing, or were as boring as a classroom.

So I asked a different question: how well could AI teach a true beginner a language this hard?

I built the first version for myself. Then I kept using it and improving it over time. I was learning faster than I had any reason to expect.

Then eventually, my teacher needed a name... Surang, a real Thai name (สุรางค์) meaning "bright light." She was the teacher I needed to teach me this difficult language.

The fluency meter is the one I track my own progress on, and it's growing steadily every day.

So whether you're learning Thai because you have to, or simply because you want to, Surang is built for you. By someone facing the same challenge.

From beta testers

The vocab was useful, pronunciations spot on, and the format was user-friendly.

— English teacher, Thailand

Surang does a solid job at distinguishing dialects, and giving accurate vocab.

— Intermediate-Advanced Learner

I didn't speak any Thai before using this app. I was thoroughly impressed by how much I learned (without having to pay a dime).

Surang's first question.

What's your goal with Thai?

Common questions

Is this for you?

How long does it take to learn Thai?

Honestly? Depends what you mean by "learn." The U.S. Foreign Service Institute classifies Thai as a Category III language — around 1,100 hours to working proficiency. Roughly an hour a day for three years.

You don't need fluency to get value, though. Basic conversations come in months. Ordering food, asking directions, reading menus — weeks. The fluency meter on your home screen shows exactly where you are at every stage.

Do I need to know Thai script?

Nope. The choice is yours.

If you want to learn it, we teach Thai script gradually from your first lesson — using see-hear-connect (script + sound + meaning together) so it never feels like a scary separate phase. Even basic script recognition helps with tones, since Thai script encodes tone information romanization can't.

If you'd rather focus on speaking first, we'll tailor lessons that way.

What's different about Surang?

Three things, mostly.

Lessons are generated for you, not assigned. Surang adapts each session to what you actually know and what you're forgetting — no fixed curriculum, no waiting for the right level.

She's built specifically for Thai. The hard parts — tones, script, classifiers, particles — are taught with frameworks designed for the language, not retrofitted from a global app.

And the fluency meter measures real skill, not time spent. You see exactly where you are on the CEFR scale, what you've mastered, and what's slipping.

What's the open beta?

speakthai.ai is in active beta — meaning the core app is live and working, but we're continuing to refine features, fix edge cases, and shape the product based on real user feedback. Joining now gets you full access to everything the app currently offers, and a direct line to influence what gets built next.

Beta users help shape the product in real ways. Bugs, requests, and feedback go straight to me, and changes happen quickly. As features improve and stabilize, beta users get the benefit of being there from the start — including any early-user perks that may come with launch.

If something breaks or feels off, send a quick note and I'll see it.

Is this on the App Store or Google Play?

It will be. We're testing the open beta on the web first, but the mobile apps are coming soon!

Is it really free?

Yes — speakthai.ai is completely free while it's in open beta, and there's no credit card to get started.

As the app grows we'll introduce paid tiers, and we plan to keep a free way to learn Thai. Beta users get grandfathered access to whatever the early-user perks turn out to be.
