I use it a couple ways. I am learning Hindi and while it's the third most spoken language in the world there really isn't that many resources for learning it. Sites like Babel don't have a Hindi course. I started with Pimsleur which is by far the best resource out there. It's mix of vocab and conversation done in an incredibly effective way. They only have two levels for Hindi so it's not a lot. With that base I use ChatGPT in the following ways.

- With the new GPT Voice, I have basic, planned conversations. Let's go to a restaurant. Let's say we're friends who ran into each other. etc...

- I use it for quizzes. "Let's work on these verbs in these tenses. Come up with a quiz randomly selecting a verb and a tense and ask me to say real world sentences." "Quiz me on the numbers one through twenty".

- I am using it to help learn the Hindi script. I ask it to write childrens stories for me, but I ask it to write each line in the hindi script, then phonetic spelling of the hindi script, and then in english so I can scroll down and see only the hindi first, then if I have issues I can see the phonetic spelling of the hindi. Then I can try to translate it and then check the english translation on the third line.

Those are the main things I'm doing. I don't know if I'll ever be fluent, but I find if you work on these basic ever day conversations you can have a conversation with someone. If you speak a language for the first time around a native speaker it's usually very predictable. They'll ask how long you've been learning, where did you learn, have you been to <country>, and you can direct the conversation by saying things about where you live and your family, etc... That's the base I'm building and it's fun. If you're not doing at least 30 minutes a day you're never going to learn a language, you probably need an hour more a day to really get fluent.
