Acts as a trusted inbetween that takes the hit on all the tracking for you and you need no account.
There would be a self-hosted server with a webinterface, where you can choose which of the popular chatbots or hosted open source models you want to ask.

Basically like duck.ai but without a big company involved.
I'm running the docker container on my home server behind my firewall on an - I think - 6070 GPU (may be a 3070 - it's one of the cheaper, older ones).
It's a wee bit slower than one of the cloud based LLMs, but my data stays local. I like the Qwen model.
