I just tried it - didnt wanna stay with it, because there is so much like that out there.
But it convinced me, because:
- the discord-channel is very response and fast
- the number of models are quite perfect for me
- the credit system is fair
- the option for a knowlededatabase, KI with search, KI with deep search and so on is quite good
- the prompt-safer, prompt-optimier, creative tools and a lot of this stuff is something you need often and so its quite awesome
- the roadmap: i am very happy when voice mode is live and also the ability to create custom chatbots (right now only something very similar to that is possible)

I used it very succesfull for: programming, copywriting, creating quizzes, create a learning-chatbot for my new field that i wanna learn, simple tasks, proofread and more. in all cases i was very happy with it :)

not so nice:
sometimes (espaciall claude 3.7) does not work for a short period of time.

all in all i am very happy with it.
