“Too bad I don’t know anyone outside of the country, because this would be a no-brainer for a native speaker.” This is the exact problem that HiNative solves. How do you say this word in Japanese? What are some foreign dramas you can recommend? From language to culture, you can easily find the answer on this global Q&A platform. Over 110 languages are supported, including English, Spanish, Chinese, Japanese, French, German, Portuguese, Korean, and more. Over 4.2 million users have registered, posting over 11 million questions with 40 million answers and counting.
