That startup is called CodeRabbit and damned if it doesn't come up with good suggestions sometimes. Other times you have to overrule it, or more likely create separate PRs for its suggestions, and avoid lumping a bunch of different stuff into a single PR, and sometimes it's stupid and doesn't know what it's talking about, and also misses stuff, so you do still need a human to review it. But if your at all place where LLMs are being used to generate large swaths of functional code, including tests, and human reviewers simply can't keep up, overall it does feels like a step forwards. I can't speak to how well other similar services do, but presumably they're not the only one that does that; CodeRabbit's just the one that my employer has chosen.
