How do we ensure translation quality?
Professional linguists only
All translators who apply to work with Nitro and/or on Alconost projects must first pass our examination. Only 2.5% of applicants pass the test and can work with Nitro or Alconost translations.
Glossary and translation memory
With Nitro, you can create your own glossary and translation memory, so that translators can be more accurate and have the opportunity to dive into the specifics of your project.
Comments and feedback
Nitro allows you to leave comments and attach images and/or interface screenshots for the translator within the order. After your order is assigned to the translator, you can leave extra comments and communicate with the translator directly.
Continuous quality control
We constantly monitor the quality of work done by our translators by reviewing customer feedback via our supervision system. Only translators with a consistently high standard of work are allowed to work in Nitro.

Text translation API example usage
Ordering text translation is easy with the Nitro API. Just insert your source text, specify the context, choose the languages you need, pay for professional translation, and get the finished product.
Case Study: One major client uses the Nitro API to translate search ads into 28 languages at once. Using the Nitro API lets them save time by not having to log into their account and go through the usual checkout process. The client has uploaded a glossary which they regularly maintain, guaranteeing them high-quality, consistent translations in less than 24 hours.
