The link to verify email doesn't work. I get the link in my email, i click and i get to the login page. I login, it asks me to verify email that sends the link again. Over and over (3 times) and nothing happens. Then I get blocked and told to try again. Then I checked the reviews and their experiences are even worse than mine. So, I uninstalled it.

It's not exactly unlimited. Sure, by subscribing, you get access to all the models, but there are daily limits and monthly limits. If you go past that, then you have to wait until the daily limit goes back to 0% or wait the month when it goes back to 0%. If you want to get more usage, you have to buy more. So, it's up to you.

The best "All in one AI suite" I've tried several apps and web apps of this type and I Merlin AI is the one I ended up choosing. Both their website and their app are very well designed. They look smart and clean. Nothing of those extra bells and whistles you see on other sites that overwhelms the user and makes it look cheap. Merlin has this great feature "Merlin Magic" that selects the best model for your promp. This is very handy when you're not sure which one is the best model to choose.
