Feels like raising a child.(Dimage Share Inc., Mr. Fukuoka)

I use YarakuZen to translate Japanese articles into English and release them as news in our company's media site. Thanks to YarakuZen, it takes me up to an hour to translate texts that would otherwise take half a day. The more I use YarakuZen, the smarter it gets, so the amount of text I have to edit after using machine translation gradually decreases. Saving phrases feels like raising a child, and we believe it is a unique feature that sets this service apart from others.
