Right now I'm building a tool that takes a student's stats — grades, test scores, extracurriculars, and the rest of a typical application profile — and works out realistic acceptance chances across different universities. Instead of a vague “your GPA is good” answer, the goal is a real, data-backed estimate of where you stand, plus a clear picture of what you'd actually need to change or improve to secure a spot at a school you're aiming for.
On top of the chance prediction, it can also rate application essays — giving feedback on where they're strong and where they fall short — and I've got a lot more planned beyond that. It's still very much a work in progress, so I don't have a public link to share yet, but I'll post an update here once there's something ready to try.
