Sorry, yes, there are paid options! But it is 100% free for unlimited chats with the Smart Lemon Cookie 7B cloud-hosted LLM, or with any locally hosted LLM. You do have to pay for saving chats, better cloud-hosted models, or image generation.
For some context, I'm just one person building this project as a side-project, and I use all the money I make to pay for GPU server renting, and to pay coders to help me out.
Sorry if the app's not for you though, I totally get it. I will say though, if you want to try out the paid features of the app, I offer a 100% refund policy, no questions asked.
