Pricing Policy

MK-TTS offers two main payment options: a subscription plan where users pay monthly and continue to use the service, and a Pay as you go plan where users only pay for the services they use.

Subscription Plan

The subscription plan is for users who already have an OpenAI API key. Users can register their API key and use the service.

The type and amount of API calls made to OpenAI's servers are charged according to OpenAI's pricing policy, and our company does not intervene in these charges. Therefore, we do not bill any charges for your API calls.

However, our service provides a user-friendly GUI (Graphic User Interface) that makes it easy and convenient to use your API KEY to utilize OpenAI's AI technologies. Therefore, we charge a nominal subscription fee for using the GUI service.

BASIC MODEL: $1.0/month

The BASIC MODEL is a Standard Model that outputs natural speech from the text you enter, regardless of the language of the text, and provides it as an MP3 file.

PLUS MODEL: $1.9/month

Subscribers to the Plus model can use an enhanced model that includes an AI automatic translation feature in addition to the Basic model. Using the GPT 4 model, it naturally translates the language you input into the language you want and provides the voice.

Pay As You Go Plan

Light users can use the service by purchasing Credits and then using these credits. Users are only charged for the amount of service they use, deducted from their Credits, and can continue to use the service by recharging if they run out of Credits. PAYG users can use both Basic and Plus models.

AI Automatic Translation Usage is Measured in Tokens

When using "PLUS MODEL," in addition to charges based on the number of characters for TTS, additional costs may be incurred for AI-based translation or analyzing translation sources uploaded by users. Usage is calculated in tokens, and your available credits will be deducted based on the amount of tokens used.

The AI model analyzes videos (including URLs), document files, and image files uploaded by users for translation. It then translates the returned results into the desired language. The input and output text generated during this process are measured in tokens.
The relationship between credits and tokens is as follows:

Token Usage Credits Used for Input Credits Used for Output
1 token 0.000006 Credits 0.000024 Credits
100 tokens 0.0006 Credits 0.0024 Credits
10,000 tokens 0.06 Credits 0.24 Credits
100,000 tokens 0.6 Credits 2.4 Credits
1,000,000 tokens 6 Credits 24 Credits

Refund Policy

  1. Refunds due to simple change of mind after payment are not allowed.
  2. Refunds for unused portions due to no longer having plans to use the service after payment are not allowed.
  3. Upon membership cancellation, all user data, including remaining Credit information, is deleted, and refunds are not possible.
  4. Users cannot request refunds or compensation for temporary server problems or other computer malfunctions that are not permanent computer failures.
  5. Purchased credits cannot be transferred between users.
  6. In cases of permanent cessation of service, or closure, and it is no longer possible to provide the service, refunds for the remaining credit amount can be made upon the user's request. If payment was made through a payment platform, the remaining amount will be refunded after deducting all fees from the payment platform. In such cases, the user’s refund request period is within one year from the service termination date.

Tokens: Tokens are the smallest units of meaning for a language model, used to calculate the cost of processing text. Each token can be as short as one character or as long as one word. For example, the word "hello" is considered one token, while the sentence "Hello, world!" is considered four tokens.
