Yes, this would be such a game changer for the research world. If you can do this for journal papers, i.e.

1. search paper title/abstract/content

2. find relevant papers

3. feed relevant papers' content into GPT-4

4. let GPT-4 answer the original questioon

it would help researchers a lot. Would likely not be feasible due to copyright bullshit though, since most journals are paywalled.
