is there any way to test claude for free?

i want to use claude, but i don’t know where i can try it for free. i live in brazil, and 20 dollars is a significant amount here. i tried using antigravity, but the quota ran out very quickly and now i have to wait 7 days for it to renew, even though i didn’t manage to get much done. is there anything similar to antigravity, or any kind of student plan available? i’m not sure what options exist.
