Cotrax

Cotrax is a practice ground for the conversations people put off. You describe the situation in your own words: who is involved, how you stand with each other, what happened and what you want to achieve. From that, Cotrax builds a counterpart who reacts believably — they dodge, get personal, point at others. They do not give in to be polite. And they do not know your goal: they only find out during the conversation what you are driving at. Then you call and talk. Afterwards you read what worked: every line you said, quoted on its own, next to a wording that would have carried further. WHAT YOU CAN PRACTICE • Giving critical feedback: raising something without it escalating • De-escalation: finding your way out of a heated situation • Setting a boundary: saying no without damaging the relationship • Delivering bad news: announcing an unwelcome decision and holding it • Mediating between two sides • Plus sales conversations: objection handling, price negotiation, cold calling, closing, complaints and more WHO YOU ARE FACING Not a textbook role but a power relationship. An employee who reports to you pushes back differently than a manager does; an angry customer differently than a neighbour. That changes what someone allows themselves — and what hurts them. A counterpart who suits you, or does not, can be saved and called again — tougher, more irritable, in a different practice area. That is how you notice the third call goes differently from the first. HOW IT IS PREPARED You can fill in every field yourself. Or describe the situation freely, paste an e-mail thread or upload minutes — the AI sorts out who is involved, the occasion, the goal and the resistance. THE FEEDBACK No praise, a finding. Five criteria per practice 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. If you like, set a weekly goal and get a reminder. 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. A trial call works without signing in. 42 conversation languages and ten voices; the app itself speaks German, English, Spanish, French, Italian, Polish and Czech. A NOTE ON AI Cotrax uses language models from OpenAI. What you enter is sent there to build the scenario and to produce the feedback. The person you talk to never sees your goal for the conversation — that is the core of the exercise. Details are in the privacy policy. WHAT IT COSTS Nothing for now. You sign in with a link sent by e-mail, no password. The servers are in Germany, no recording of the conversation is stored, and there is neither advertising nor analytics.
