As the name suggests, a multilingual website is a website that has content in more than one language.
An AI-based multilingual website allows you, purely through editing in your native language, to make it available in all common languages. Without additional effort, fully automatically, at native language level.
While it is true that the English language is still dominating the internet (statistics show that 25.2% of internet users speak English), there are other languages that are used widely, such as Chinese, Spanish, Arabic, Portugese and others. Take a look at this super useful chart from Statista from 2019.
The top 10 languages count for 76.3% of the global internet users, which is a significant number.
Now, imagine if you added Chinese and Spanish to your English-only website. This would give you the opportunity to reach 27.2% more of the internet users, which is exactly why multilingual websites are important.
