KA Polyglott is a free web browser extension developed by KA Deutsch for foreign language speakers who want to learn on Khan Academy. This unique tool aims to bridge the language gap by providing translations of texts and videos in multiple languages.

With KA Polyglott, users can easily access translations of video titles and descriptions with just a mouse click. The extension also includes a text-to-speech engine, allowing users to listen to the translations audibly.

One of the standout features of KA Polyglott is the ability to switch between videos in different languages using flags displayed on the right side of the screen. This feature is especially useful for learners who may not fully understand a video in the default language and prefer to watch it in their native language or any other language they are comfortable with.

It's important to note that KA Polyglott is not an official Khan Academy application. However, it serves as a valuable tool for foreign language speakers looking to enhance their learning experience on Khan Academy.
