Is it possible to add a mode that doesn't depend on API access (e.g. copy and paste this prompt to get your answer)? Or do you make roundtrips?

There is a fully local mode that does not use ChatGPT at all – everything happens on your local machine.

API access of ChatGPT mode is needed as there are many round trips and it uses advanced API-only tricks to force the LLM output.
