Wanna have a more enjoyable experience when reading VN. Over the course of the years, I have tried many different apps to improve my quality of life when it comes to reading visual novels. In this article, I will showcase all the free apps and their function that I have found useful.
Wanting to read VN but don’t have localization yet, or you want to learn Japanese by reading VN. Luna Translator has you covered. This app will hook the text from VN and translate it with an online translator such as Deepl. However, if you have a powerful GPU and a sufficient amount of VRAM, you can also use Local LLM (AKA “AI”) to do the translation locally. Wait, there is more, it can also grab the hiragana from kanji too. Below are some examples of how the app can be used, and “here” is the details setup tutorial for Windows. If you are interested in running this app on Linux, please check out “here”.
Example 1: On-screen translation
Example 2: It can replace the original Japanese text with English
Note: Not all games work and may experience crashes

A tech giant like Microsoft can’t even figure out on building a brightness slider for an external monitor. However, twinkle tray figure it out, and it is simple to use as well. Just install it, and you are ready to go.

Example 2: You can also set a shortcut key to do the brightness adjustment
