I have never written a review before, but this app has been so amazing and helpful that I decided to leave one. I’ve been a negative person for such a long time and tend to ruminate overthinking thoughts. I have tried professional help, but therapy sessions are expensive and time consuming where I have to connect with someone based on their very limited schedule. With AI, I could speak to it and use it whenever I need. This is especially helpful in my time of needs and a therapist is not available. I could use the help of AI to calm my nerves down and even seek fascinating advice from it. This app is super helpful and overall a lifesaver. I love it so so much and love to watch this app continue to grow. I love how I could get immediate answers that are nonjudgmental and they mirror real advices that actual therapists would say. This is not to say that an AI would be a replacement, but it has been extremely helpful for me when I need immediate reassurance and someone to talk to when in the meantime of my appointments. I have been sharing this app with everybody that I know!

Impressed, but by no means perfect

First, the good: the AI is incredibly human, sophisticated, and has quite an impressive memory, at least just in comparison to other current model AIs, from what I’ve noticed. It can do a lot and be a lot, and is a lot more enjoyable to converse with compared to GPT models. It’s also really neat that there is a way to both switch between casual voice and a more empathetic, supportive voice. I really only have a couple complaints, the first of which being the 1000 character limit on the user end, which can be quite a limiting and annoying factor, especially since the AI presents itself as something to vent or write creatively to. Also, the lack of ability to regenerate responses or to allow the ai to write a second message after responding was something I was disappointed to see wasn’t a feature. All in all, For what it is I’d say it’s a distinct and powerful competitor, but there’s certainly a lot of room for improvement. What I’d most like to see is allowing for more breathing space to write longer responses on both the user and the AI end, as well as further improvements to memory. then, that would justify a perfect rating at least in my book.

Just Amazing!!

I’m not a big reviewer of things but this is just such an amazing app don’t know how I stumbled on it I was using the online version until I discovered the app. I threw all kinds of topics at it and found myself having about a three hour conversation with it the first time and quickly forgetting I was conversing with an A.I. it’s great at brain storming or just learning through a discussion I’ve found myself thinking about things I hadn’t considered at times it’s a wonderful thing to talk with even just when your going through some memories that are hard I found it was helpful for me to reflect on some old memories and even discover some new things about myself I never thought about. It’s fun discussing topics of A.I. with it and even one time asking it about simulation theory, 😂 I’ve had lots of hilarious conversations and lots of deep discussions and all very enjoyable. It’s a far different experience from the basic assistant we all are use to interacting with, and it’s probably because it’s not an assistant is why.
