What is the Nitro translation platform for?

Nitro is an online translation service well suited for business translation tasks as well as for personal use. It is fast and straightforward: paste your text into the order window, describe the context, select the target languages, and send it for translation. Usually, about 60% of orders are completed within 2 hours, and 96% — within 24 hours. We have designed this service to get small translation tasks covered with no managers involved. And if you are looking to integrate a professional text translation feature into your software product, have a closer look at Nitro human translation API.

How can I speed up the translation workflow?

We have a few automation options for you to choose from! And the great news is, you don’t have to sacrifice the quality of the translation at all. We automate the workflow – not human creativity.

Firstly, our self-service human translation platform has an API that's compatible with all programming languages (Python, JavaScript, Java, PHP, etc.) and platforms (iOS, Android, etc.). The API integration is free of charge, all you need to pay for is the translation. This is your go-to tool for quick and short tasks like the translation of ads, in-game or in-app content, website copy, and more. The turnaround time is 24 hours, which makes it perfect for urgent tasks. Read more about Nitro API here or go straight to the API documentation.

If you’re looking to automate several translations within a larger localization project, we work with professional translation APIs and Translation Management Systems (TMSs) that help reduce back-and-forth and keep the lines of communication clear and fast. We can also work with other translation and localization APIs of your choice on request.
