Anyone found a sales AI that actually helps during the call, not after it?

Most AI sales tools I've looked at focus on what happens after the meeting: transcripts, summaries, coaching, call scoring, and reports.

I'm more curious about the live-call side of things.

Have you come across any tools that can surface answers, objection handling, competitor intel, pricing info, or CRM context while the conversation is happening? Not post-call coaching, but real-time assistance that helps reps in the moment.

If you've tested anything in this space, what worked, what didn't, and where do you think current solutions still fall short?
