Why localization matters

Mr. Beast has over 150M subscribers on YouTube.

Whether you love him or hate him, we have to agree on one thing: he knows how to create content to reach millions of people.

One of the lesser-known facts about his business is his dubbed channels.

Jimmy understands the value of bringing his work to people's native languages. 

So he translates all his videos into multiple languages. 

In this interview, he showcases the impact this practice had on his channel.

The localization process for big projects like games or enterprise applications can be very painful.

Our goal is to streamline this process as much as possible.

This way you can focus on the product without worrying about translating strings.

The Tolgee Unreal integration

There are 2 main things we focused on when it comes to this plugin:

1. Runtime translation: updating translations in the Tolgee web interface will seamlessly update your running instance

2. Seamless integration: after you complete the localization setup for a project, you can upload all your keys in 2 clicks after enabling this plugin

The best part is: you can use this plugin on top of your existing setup

For instance, if your game is already running in English & German you can leverage Tolgee to add French without changing your current setup

The plugin has reached a stable enough state to share it with the public but we are actively working on improving this for you

We are happily waiting for your suggestions and your contributions
