Generative AI chatbots are nice, but occasionally, if you want a chatbot to do something in a very specific way, it should usually be preceded by feeding it countless prompts and instructions for it to work exactly the way you want it to. Purpose-built chatbots are a partial solution: they are geared towards doing one specific kind of thing in an exact way, requiring less work. OpenAI previously announced GPTs as pre-trained chatbots for this purpose, and now, the promised store for them is finally going live.
