If you’ve ever stumbled across a great dev tutorial—only to realize it’s in a language you don’t speak, you’re not alone.
Whether it’s a Japanese Docker walkthrough, a Brazilian React Native deep dive, or a Chinese AI course, there are now tools that can translate, subtitle, or dub those videos so you can actually follow along.
Here are 7 great tools for developers who want to learn from global content:
1. Addsubtitle

2. YouTube Auto Translate (Built-in)
