I’m building a stress-tester for grants before submission

I’m building a tool that stress-tests submissions before they go out — running independent critique passes across multiple AI models, then synthesizing the recurring concerns into what I’m calling a Vulnerability Map: a structured view of where reviewers are most likely to push back.
It’s not trying to predict reviewers. It’s trying to show you which fault lines come up again and again before you submit, so you can decide what to fix and what to defend.
Still early — curious if this resonates with anyone who’s been through the grant cycle recently. What kinds of feedback blindsided you the most?
