Dear Shangyu, I use Anki, and I fill it with Hebrew!!! : ) It works beautifully. It is currently my main memorization card tool.
Tell me what you are doing, I might help you along. First of all, do you have Hebrew enabled on your computer? If not it is very easy to enable it, and then Anki should be happy then to receive Hebrew. If you want to activate Hebrew on your computer, it is easy, I put an explanation in a comment below the discussion:

If you are still having problems, ask me, or go to the help page for Anki and post a question. Maybe get also the newest Anki download. It's free.
