How to Choose the Best Translation Tool For You

A lot of services on the Internet can translate text and documents for you. And most use the same Google backend API to convert documents from one language to another. However, good tools add artificial intelligence, machine learning, and a personal touch to make your documents extra precise.

Here are some key features that a good automatic translator will have.

Lots of Languages

Language is worldwide and your smart translation service should support all the specific languages you need it to.

Good Accuracy

Ideally, you should have a native tongue speaker verify that your translation is correct. Or, compare different tools by running the same text through multiple tools.

This will help you understand which tool fits your needs best.


Good smart AI translation tools will consider SEO and other good search practices in your translation. Unlike English, lots of other languages can be expressive in multiple ways. A good tool will understand which context to you.

This process of translating, localizing, and SEO optimizing is called Translation Management.

Free Translation Tools

You will find free services at your disposal. But in that case, we recommend Google Translate (featured below). Translate is a free offering from Google that does free language translation. It is fast, generally reliable, and supports over 90 languages. The end quality is average or better.
