Account & Payment

Is there a free trial?

Yes, when you sign up for a free Mirinae account, you’ll receive 14 day trial of unrestricted, Pro access to all of our learning features at no cost or obligation.


You can use the trial period to fully explore our offerings and decide if they meet your needs. At the end of the trial, your account will automatically revert to a regular Free account, still with unlimited sentence explorations, but with limited details and feature access.   Or, you can subscribe at any time to keep using all the Pro features and lessons by clicking on one of the “Subscribe to Pro now” buttons.

Do I need to cancel the trial

No, it will automatically cancel itself after 14 days and revert your account to a regular Free account.    You will not be subscribed or charged anything, the trial is completely free, and requires no credit card or commitment to purchase a subscription.


When you account reverts to a Free account, you will continue to be able to use the Mirinae analyzer to get summary sentence explanations, but you will not be able to access Mirinae Lessons or some of our advanced tools, such as the OCR image reader or Listening Practice Tool.


You can subscribed to a Pro account at anytime, during or after the trial, just by clicking on any of the Subscribe to Pro buttons that will appear if you attempt to access a Pro level service.


Why did you adopt this subscription model?

Mirinae Beta has been free for quite some time, and we are very pleased that so many learners have found it a unique and valuable learning aid. It has taken a lot of effort and resources to make this service available, and we now need a viable way for us to be able to continue to do so and to add more useful learning tools.


The most direct and cleanest way for us to do this is to establish a subscription model. We have tried to price it modestly, so it is in reach of most of our users, and we continue to provide free, unlimited access to the analyzer and its top-level explanations.


Perhaps the most valuable asset and the one that has taken the most time and effort to build is the grammar and idiom pattern library that underlies the analyzer and its reference results. It is, as far as we know, quite unique, and although we were reluctant to put some of the deeper reference material into the Pro plan, we felt we had to account in the subscription model for its uniqueness and the effort it has taken to build it.


We hope you will understand this move and will consider helping us keep the service going and continue the development of our services. We have plans to add many more learning resources and they will, of course, all be accessible under the paid plans.


And if you have any ideas for additional tools or services that will make a paid plan more palatable to you, please let us know!!

What comes with Mirinae Pro?

Do I need a separate Mirinae login account for every device?

No!!  A single Mirinae account is all you need!


Since we allow signups via multiple login services, people sometimes create multiple accounts and login in different ways at different times. We recommend you create one account and use it on all devices and desktops, so that your history and lesson tracking and any Pro subscription you have is active and available across all your devices and desktops.

My Pro account has disappeared!

This should only happen if you cancel your account, and even the, only at the end of the subscription period in which you canceled.


Sometimes, your Pro status might seem to disappear, but please ensure you are logged into the Mirinae Account you were logged into when you subscribed. Since we allow signups via multiple login services, people sometimes create multiple accounts and login with one of the alternate accounts. Any Pro subscription is tied *only* to the single Mirinae account you subscribed under, and you may login under that Mirinae account on any supported device or desktop.


If you have followed the above advice and still seem to have lost your Pro status, please contact us on and we will assist you.

How was Mirinae created?

John Wainwright who is an Australian computer scientist and CTO of Mirinae became interested in Korean culture and started to learn Korean some years ago.


He was intrigued by how difficult the Korean language is for English speakers and yet how beautifully simple and elegant Hangul is.  He learned Hangul in a weekend, but he is still struggling with Korean!


A particularly difficult aspect for Korean learners when they encounter written Korean is to understand the structure of the text.


From his background in programming language design and machine learning, he realized it would be possible to build an automated analyzer that could break down encountered Korean into all these components and explain this complex structure in detail.


This would allow any encountered Korean to become “comprehensible input”, a crucial component in acquiring a language.
