The Crowdin application is an advanced but at the same time very intuitive tool available online. This is paid software, but there is a free demo version that allows you to use the application for 14 days free. If you plan to use the application once, you do not have to choose a paid plan. If you intend to perform translations regularly in a professional manner, we recommend choosing a paid plan. The application has built-in options to facilitate mass translation, such as: translation memory, machine memory, or autocorrect.

A single translation can be made in a demo version of any of the above-mentioned applications.
