Ask HN: What AI tools help me understand a MR?

I'm trying to incorporate AI code tools into my flow, but my issue is that I spend a lot of time code reviewing AI. I know there is vibe-coding vs engineering and I'm trying to stay on the engineering side while trying to figure out how to properly use AI. In that spirit, I wanted to find an AI tool that helps me code review better. More specifically, look at a diff and present it to me in a way that makes it easier for me to understand what is going on. I am not looking for a tool to do a code review in my place. Does anyone have a flow or tool they use already to do this? Thanks!
