Ask HN: How do you use LLMs for private discussions?

I sometimes have things to discuss with LLMs, which are more private than usual. I was thinking how to do it in a way that doesn't reveal my identity.

  1. Use Tor to access the provider?
  2. Create a random account?
  3. Use some form of untraceable payment (which one?)
  4. Scrub all information provided to the LLM from personally identifiable information?

It seems like a lot of effort. So is running a local LLM, for which I don't even have the hardware. How do you do it?
