I have been reading Deep Sea Embers. It is one of the best ongoing novels, so I just couldn’t stop myself from wanting more. What are my options? Go to machine translation sites like Novelhi or Wuxiamtl and read there or use the Google Translate extension.

The below texts are just my ranting. Go to the method to translate directly.

It’s one option but the texts are so bad, that there’s honestly no different reading from LNMTL. Fast forward, I reached 700 chapters of Deep Sea Embers. It was a painful read.

Then it hit me to use LLMs like ChatGPT and Claude. But the thing is they sometimes translate incorrectly and sometimes, they start to produce nonsense text. You need to learn prompt engineering to get good results.

Let’s not forget the pain of copying and pasting text chapters every time.

Finally, I decided to make a Python script that scrapes the chapter and uses OpenAI API to translate the text. So I went ahead and learned web scraping…. Fast forward, this method doesn’t work. Though it was easier as I didn’t need to copy and paste but output was not as expected. Sometimes I got a summary or sometimes gibberish. Let’s not mention that not everyone can get API access and the cost associated with it.

Finally, Today everything clicked together and Now I present you the new method of machine translating Webnovels FOR FREE.

Step 2: Get the API

I will tell you two methods of getting free API. First, Let’s get Google’s Gemini API.

Gemini API is on par with ChatGPT, so the translations will be better.

You can follow this YouTube video on how to get the API key.

Warning and Errors While MTLING Novels

This method is not perfect. There will be translation mistakes as we are not translating the whole text but only translating one paragraph at a time, so there will be many mistakes with the names especially in Korean novels.

The next problem is that Gemini only allows 600 requests per minute. This generally won’t pose any problems but in some cases, you may get Response Error Window from Immersive Translate. If you get this error, just wait for some time and retranslate. This is sometimes the case for Korean Webnovel as they have short paragraphs and high word count.

Gemini API limits

If you feel the above problem is significant, you can use OpenAI API. GPT 3.5 will be enough and it generally costs very very low (around $0.001 for a thousand words)

Translating NSFW novels will not be possible with Gemini or OPEN API as it will either show an error or refuse to translate. (sometimes it does translate NSFW but it will be heavily censored.)

However, fear not. I have a method.
