What professionals say

How professionals put Nico to work every day.

I've used it for both Japanese-to-English and English-to-Japanese. It's a great service that lets you pick up keywords and word meanings while you translate. I get to learn the words and phrases I use most often and put them into practice in real conversations and at work, so I'm learning English very efficiently.
Translation & language learning
Translation in both directions is fast, smooth, and easy to use. I used to rely on AI tools like ChatGPT to write emails in English, but typing out prompts was a hassle. With this app, I just write what I want to say in Japanese and it instantly produces natural English โ€” it makes everything so much easier. I'd recommend it to anyone who writes emails in English or switches between Japanese and English every day.
