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 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 — 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.
Nice work! Really cool app! 👍 I will continue using it daily
