Hello Magdalena. I'm glad you like Italki! I love it too. It's really nice to practice languages. Italki has a credit-function, which allows you to teach other people in order to obtain ITC (Italki credits) that you can use later to get lessons from someone else in the language that you are learning. Other than that, it's completely free to use this website, which is the reason why it's so amazing! :) Good luck with your language learning & teaching.

hi, thanks for your answer. I wondering if this portal is absolutely free (without lesson with teachers of course)

Hello, this website is very nice, you practice and you make friends :D
