There are tools that use LLMs to do this.

I've done this manually by building a big feature branch and asking an LLM to extract out functionality for a portion of it.

For the former, it would seem to split based on frontend/backend, etc. rather than what semantically makes the most sense and for the latter it would include changes I don't want and forget some I do want. But I haven't tried this a lot.
