Using AI to prep managers before performance reviews. What are you doing?

We're a 50 person company and review season is coming up. Our managers keep saying they dont have enough context on their direct reports when its time to write reviews. Someone suggested using Copilot to summarize Teams chats and emails but that feels like it would miss the actual performance data like goals and feedback. Whats everyone else doing to help managers prep for reviews? Is there some AI-powered tool that pulls together the actual relevant stuff?
