I was tired of paying monthly subscriptions for all my AI tools and I wanted to pay just for what I use so I combined the AI chats I use to create my own chat - MyChat (pun intended)<p>MyChat is an all-in-one chat bot that has a pay-as-you-go business model.<p>The tech stack I used was NextJS, TypeScript, MongoDB, Clerk, TailwindCSS, ShadCN, Stripe, the OpenAI API hosted on Hostinger with Coolify. The code base is currently around 3500 lines of code. (About 500 of them are redundant code)<p>The web app itself is not complicated the only complex thing in it is the math that's mapping the different api tokens to MyChat tokens, but it's also my only competetive advantage so I sadly can't even share it.
