I invested 500 rubles. I tried Claude at the basic level. I asked a question and received the response "provider error." The same thing happened during my second and third inquiries. In the end, I lost 200 rubles. There is no support. I received an email saying: your request has been registered. Just like at the housing office. Then I got a notification about insufficient funds. According to the site's rules, one should be polite. I follow this rule. I do not recommend it.
