The application does not work correctly and all its results are wrong. I used Claude in the application and all the results were failures and had no connection to the original site. The worst part is that I was subjected to fraud on my credit card and money was stolen from it, with an attempt to renew nine months before the end of the year. The strange thing is that when I stopped the card, they sent me an email asking me to enter the new card... blatant fraud. I subscribed and have not benefite

Merlin AI is incredibly frustrating. I bought Pro expecting a better experience, but sponsored links kept appearing—even links that weren’t relevant to my Android device. It feels more like an advertising platform than a useful AI assistant. It was also advertised as unlimited, but I found I only had a certain amount of credits. That felt misleading and disappointing. Overall, the experience has been annoying, and Pro hasn’t felt worth the money. I wouldn’t recommend buying it.

Don't waste money, even pennies. Just go to the model itself and ditch all middle men. Even at the HUGE discount at 2 eur/month, this is completely useless and acts close to a free service. I guess it can be usefull if you want to test Astra without paying OpenAI a whole month. The lack of a desktop agentic work is just mind blowing.
