Sales Call Trainer
Read full descriptionHide full description
Sales Call Trainer is a practice ground for sales conversations — with someone on the other end who does not buy out of politeness. You bring in what you sell: a web address, a PDF or a few sentences. From it the AI distils target customers, value, the questions that come up and the objections that actually land — and builds a person with a role, a history and an interest of their own. Then you call and speak. Your counterpart interrupts, dodges and does not give in because you asked nicely. After you hang up you read what landed: every line you said on its own, quoted, next to a wording that would have carried further. WHAT YOU CAN PRACTISE • Objection handling: "too expensive", "no need", "not interested" • Cold calling — the first twenty seconds • Reaching the decision-maker, past the gatekeeper • Needs analysis with questions that surface something • Price negotiation without reflexively offering a discount • Closing: spotting buying signals and securing the next step • Following up a proposal, booking meetings, upsell, pitch, complaints • Or your own case: offer, counterpart and goal are yours to set WHY IT WORKS Your counterpart does not know your offer. Price, value arguments, proof points and your goal for the call never reach them — a check in the code keeps that boundary, not good intentions. A role-play in which the other side already knows your offer is not training, it is a reading appointment. The person may stay sceptical, refuse the meeting and hang up. A close you are given for free trains nothing. THE FEEDBACK No praise, a finding. Five criteria per training goal, your own lines quoted, a better wording beside them — and the trend across all your conversations, so you can see where you are improving. SPEAK OR WRITE Spoken in the app, with interruptions and time pressure. Or take the finished scenario to the AI chat of your choice and bring the transcript back for feedback. 42 conversation languages and ten voices. The app itself speaks German, English, Spanish, French, Italian, Polish and Czech. WHAT IT COSTS Nothing for now. Signing in works through a link sent by e-mail, no password. The servers are in Germany, no audio of the conversation is recorded, and there is neither advertising nor analytics.
