Exploring Real-Time Buyer Insight Tools for Sales Reps

Most Sales Enablement tools focus on teaching reps what to say. But what if reps could actually understand the buyer's problem in real time, not after call , not during training, but as it's happening ? If you've used tools like this I'd really appreciate your take. And if you've seen any pitfalls team fall into when trying to fix this, I'd love to learn from those too.
