I have been working on something like this, but it actually does things and is not only chat. Each "Gov. official" has their own AI agent that can fulfill intents by navigating a protocol which is just a workflow of a Gov. process
example: https://samhsa.dev/ example: https://samhsa.dev/protocol/76526
Still VERY MUCH a work in progress but I have successfully been able to have some people get things done. I am doing some federal agencies and also trying to get cities working now.
You should message Joe Gebbia.
