If I stumble, hesitate or pitch the product too early, object or hang up. After the call, give me two things I did well and two to improve. Confirm you understand, then wait for me to start by voice.Example output
An illustration of the shape of the answer. Not a reported result.
Understood. I'll pick up as a VP of Sales between meetings. Go ahead. ... Well: clear permission-based opener; asked about ramp time. Improve: you pitched features before finding a problem; you did not confirm the calendar invite on the call.
A rep can try it this week with tools you already pay for.
The problem
Reps try new talk tracks for the first time on live prospects and burn the call.
How AI solves it
Upload your talk track, objection handling and a few real call transcripts.
Tell ChatGPT to play a busy persona who will object or hang up if you pitch the product or hesitate.
Grade three parts: permission-based intro, problem hook, explicit meeting ask with triple confirmation.
Switch to voice mode and run the call.
Ask for two things you did well and two to improve.
