English-to-Japanese, how have you done it?

An alternative to KaniWani is KameSame. It basically does the same as KaniWani although it also has JLPT word lists that you can add to the SRS as well if you want. You can also copy and paste sentences into it and it will create cards for you based on the vocab in those sentences.

What I like about KameSame is that if you enter 女 and it was looking for 女の人 the system will tell you ‘yes you’re technically right but this isn’t the word we were looking for’. It doesn’t mark the answer you input as wrong and gives you another chance at it.
