Not good for beginners

You can use it for practising but Not to learn it When you can read and speak korean It’s Perfect When Not dont try it!

BEST AI Korean app I know

So I’ve been using the Seyo app for a few months now and originally I was using jump speak and was trying to do some other things and I ended up getting a refund for that and investing into this. So I trust their reputation and figured I’d give it a try.
And honestly have to say that it has to be one of the best AI apps for Korean specifically since obviously that’s all it’s for, but the best AI speaking app that there is. Jump speak was cool but it just was too AI if you know what I mean in that it would be more generic its responses, but with this app, the amount of memory it holds, remembering your past conversations sounding like a real person and having different emotions to be able to speak and practice with is honestly so amazing. I would highly highly highly recommend TTMIK Seyo app for the AI call feature alone just because when you don’t have a lot of other people to speak Korean to like me since now I’m back in America after being in Korea, it’s very valuable to be able to have something reliable enough to speak to. Again it’s not perfect perfect, AI just can’t be that perfect but ultimately if you have good enough pronunciation, it will be able to pick up what you can say. I think that is the only downside to AI apps is that if your pronunciation isn’t good it doesn’t hear you correctly and ends up throwing something in there that you didn’t quite say and so in that way, it can be a little frustrating but to be honest with you it’s something I’m willing to work past. Simply highly recommend especially if you don’t have anybody else to speak. Korean with 10 minutes a day goes a long ways!!!

Best app for learning Korean

As a Korean language teacher, author, and native Korean speaker, I've tried many Korean-learning resources over the years. Seyo genuinely stands out.

I especially appreciate that it brings together grammar practice, pronunciation training, and open-ended conversation in a single app. The characters’ voices are remarkably natural. They don't sound robotic or like typical TTS voices. The conversations feel surprisingly close to talking with a real Korean speaker, which makes the practice much more immersive.

Another feature I really like is the ability to hide or reveal the English translations of the example sentences. It's a thoughtful design choice that encourages learners to think in Korean first and check their understanding only when needed. ⭐️⭐️⭐️⭐️⭐️ Highly recommended!

Still buggy

This app has a great concept and design, but it simply doesn’t have the ai intuition to pick up what speakers are saying. I spend most of the time yelling at the app and repeating myself over and over because the buttons don’t record on the first press or it autocorrects to nonsense. It becomes so frustrating to use, I always give up. The tools and lessons are useful but a bit short sighted, lacking application for the grammar points. I think with more development it could be a highly recommended app.

Trouble picking up speech

I really want to love this app. The interface is smooth, the lessons are helpful. But the biggest problem for me is that it only picks up half of what I say. I wait until it’s listening, then speak, and it will catch only the last word of my sentence, no matter how slow or fast I talk, or how close or far from the mic I am. I’ve tried from different devices multiple times, and it just doesn’t perform well enough to be useable. I wish it were different, because this app concept and the leveling of the lessons would be a wonderful addition to my learning.

Always having to pay

It is like this with other apps too, but at least with Duolingo you don’t have to pay for a monthly trial. They just give you the option, but with Seyo you have to pay for trial before you can do any other lessons I can’t even get to the next lesson because they want me to pay and I hate this if they can at least make you not have to pay. I will download this app again, but overall this app is pretty good. I just don’t like how you have to pay because there’s no way I’m paying that much money just to speak Korean when I can go and get Korean lessons myself…

Great But Voice Recognition Could Improve

This is by far the best app to help in my studying so far, thus why I’m giving five stars. As someone who is terrified to speak with a native speaker until I have more confidence this has been a great outlet to build my confidence. My ONLY complaint is that Seyo will clearly hear me because the AI transcribes my words and yet will give me a low grade. I can usually expect this because Seyo always takes longer to register that I’ve finished speaking in these instances. It’s fine because you still have the option to listen and compare your pronounciation to the example which reaffirms that my pronounciation was close, Seyo just could not catch it.

Love it!

This is exactly what I need for enhancing my Korean speaking skills. I love that it corrects and rates my pronunciation. I know so many words and grammar but my speaking and pronunciation skills are terrible. This app is just perfect for me so I can go back to South Korea and speak to locals with confidence. I’m so glad they have so many units and levels. Thanks!

needs some technical work

Conceptually this app is perfect, but in many areas the AI models used are not sophisticated enough. The AI conversations are nonsense or worse; one asked to borrow my phone, and when I asked why, it threatened to borrow my wallet. Pronunciation feedback doesn’t exist.

Despite that it is still pretty good, compared to your average language app

I can't access the app

Sooo I didn't even test the app cuz it wouldn't let me try it?? Like I installed it and then I clicked on it to get on Seyo and the app instantly went off so ? Idk if it's a bug or smth cuz i have the right version and enough storage i just want to know what happening because it kept happening with other apps sometimes i will redo a review once i test it if I can

A solid comprehensive course

This app is a solid platform to improve any level of Korean; the structured conversations help reinforce grammar and pronunciation without making one feel self conscious; Korean isn’t easy but Seyo makes it fun!!

PAYING

Great learning app but after your first lesson you would have to pay to go on with Seyo! Recommended unless you wanna pay.

French please

I really like Seyo but this is in English, if Seyo can as a French version I’m sur my korean become best !

So close to amazing

I love the ttmik resources, and I want to love this app and service so much, but it’s not quite there. The pronunciation help is amazing, but like other reviewers have said, it sometimes has issues with recognizing that i have spoken at all.

My real complaint is the order of the lessons. I know it’s technically a separate service from the others in the ttmik family, but I wish the lessons were in the same order as they occur in the book and video lesson series. Seyo is an amazing resource, but with the very brief explanations of grammar concepts and minimal vocabulary, it feels like a supplement rather than a whole learning plan on its own. And when I have to rote memorize large chunks of vocabulary to make it through a speaking lesson I won’t be doing the textbook written and listening work for until weeks later it’s frustrating. For a premium app with a subscription, I won’t be renewing until it is more cohesive with the rest of the company’s resources. PLEASE CONSIDER FIXING THIS. I would be a subscriber for life if this were the case.

Not good at all

I bought a year subscription because it was recommended by TTMIK which I like a lot but unfortunately I do not like this app. at all. The voice recognition is very glitchy and frequently leaves parts out or doesn’t register what I am saying at all. It’s also extremely slow to respond so getting through one lesson is very painful and frustrating.
I find the lessons do not help much with speaking as nothing is repeated so I will just forget what I learned as I hear it as a one time thing.
I’m disappointed as I really like the TTMIK website and materials. I have bought many of their books and their content is great. I’m very disappointed this app is not useful and I’ve wasted a lot of money on it.

App is having issues where it can’t hear me properly when i speak

Like the title says

Call option

The voice recognition keeps mishearing me. The microphone works, but the app doesn’t pick up or recognise what I say even if I speak in my native language. It is very frustrating

First time Use

I’m still very new to the Korean language so getting to use something that could build up my confidence in speaking and enforcing knowledge is a very big must. I see a lot of potential with the app, especially with the pronunciation registry that helps build tone and clarity with words.
On the other hand, I can also see where it can use a little more detail. For example the way the app tries to catch my voice isn’t often very good. It seems to pause too long, almost glitching, and sometimes even disappearing all together with the little green face. Also it’d probably be good to make the little green face more apparent to when it is recording the voice as it’s rather hard to tell when it is and isn’t. This is just the coding so it can be fixed.
The other thing I’d like to see is a little more connection with other things. The simplicity of the app is very nice but I don’t see a lot of correlation with what we’re being taught with the Seyo conversation starters/role play given to us. And what is being taught isn’t really being enforced past the initial lesson.
Still, it’s a new app so there is plenty of room for development!

Love it but

I love it but it keeps lagging like when I repeat something it will lag or freeze and I have to go in and out of the app and then telling me I didn’t say something correctly (when I know I did) 이건 is not hard to say. I talk to my Korean friend on hello talk who also confirm I said it correctly. The speech recognition needs to be updated or something. I changed my tone to make it lighter, I moved the phone away from being too close to my mouth and it still isn’t recognizing
