ChatGPT Messenger: Chat with GPT, without expensive Subscription

Hey Product Hunt community, I've heard from some students that their university has blocked ChatGPT on the school network, and even those who are actually allowed to use it are sticking with GPT-3.5 because the subscription is too expensive for them. I thought I could offer a solution to both problems at the same time. A messenger, just like ChatGPT, but accessible and with prepaid plans instead of monthly subscriptions. You only pay for what you need. ___ UPDATE: Meanwhile GPT4o is also available for non-subscribers of ChatGPT. This is supposedly because a GPT5 is already coming in the next 2 months, according to certain leaks. GPT5 will then again only be available for subscribers - which makes sense, otherwise subscribers would hardly pay $20+, just for a slightly higher limit. As soon as that happens, I will only offer GPT4o and GPT5 on this platform, then it will make a little more sense, as at the moment with free GPT4o the benefit is unfortunately somewhat lost. Currently, ChatGPT Messenger uses a smart mix of GPT-3.5 and GPT-4o, dynamically selecting through an algorithm the best model for your request to ensure the most efficient responses. I know that doesn't sound very impressive at first, but there are currently 5k registered users (mainly students). Let me know what you think. Cheers
