You can do this at grok.com.

There is a "start thread" option below every conversation. You can also read the responses aloud (helpful if you want to do something async).

Oh cool! Finally!!!

Unfortunately, it looks to only support single subthreads. But my questions have questions sometimes. I want to subthread conversations to arbitrary depth. If they can subconvo once, they can do it arbitrarily.

Thanks for pointing this out.
