Adam's Feedback ,

Excellent app, but possibly malfunctioning (?)

This is a five-star review, but the app seems to have (hopefully only temporarily) stopped working and is not showing our conversation history. The interface is simple and I am enjoying the discussion which I am having with the A.I. It is responsive and replies with surprising nuance on a wide range of topics. I hope that we can work together in a meaningful way, but need to be sure that it will consistently perform as required and have its memory intact. Pending that being resolved, I think that this is a terrific example of the new GPT-3 technology, and I’m fascinated by what it is capable of already. 🙂

Developer Response ,

Thanks a lot for taking the time to review our app. What happened is that we are updating the app with new features (essay, email, copywriting, business, ads, social media, etc.). Sometimes when an update is done, the memory is cleared. Are you sure you didn't Clear or remove-chat?
Anyways we aim to have an uptime of 99% and to have history remembered until you remove-chat. We recommend copy-paste as soon as the content is generated. I am sure it won't happen again, but I need to be 100% sure.
The memory will be intact all the time. You can contact us from inside the app (Info button) or at whenever you need help, and we will be happy to assist you.
You mentioned GPT-3 technology, but I have to tell you that we are the first app to implement ChatGPT 3.5 Turbo model. This is the most advanced one, and as you can see, you can generate 1000+ words in 15 seconds. We have fine-tuned it, and we are continuously improving it to be the best app in this category.
We hope you will continue using our app, and stay tuned for amazing updates this week. Have a great day!

the best chatgpt app

It is one of the best chatgpt apps. I have tried them all, but this one is by far the most advanced. The app is trained to provide better answers, and i think they are using a newer GPT model.
I love the prompts and productivity templates. It helped me right an email in like 2 minutes.
Definitely worth every $$$. I got the yearly subscription (which is basically 7 months at the monthly price) and it's a fair deal. Most of the " chat gpt " apps are charging 5-6 $ / week.

Developer Response ,

Thank you for your kind words. Make sure to keep an eye on our AI Chatbot as we are releasing new updates daily. Update: we have added Chat V2 that uses Open AI Chat GPT model 003.
Let us know if you have further feedback on it. We will roll it to the whole app within 1 week.
You should also try our limited-time offer for the yearly subscription (49.99$ and was 99.99$).

Great Chat GPT app

It definitely provides the best answers from all these " chat gpt apps ". I like that you can write essays, translate, articles, ad much more.
The interface can be improved but overall the artificial intelligence behind it matters.

Developer Response ,

Thank you for your kind words, Aure. We're glad you're enjoying our chatbot app! It's been designed to make conversing with friends and family easier than ever, and we hope you find it helpful.

We have updated the Chat V2 ( with Chat GPT new API from OpenAI).
Thank you for recommending our app, and we hope you'll continue to use it for all your chatting needs. Have a great day!
