cosskill
Rehearse hard conversations against AI personas before they happen in real life
cosskill drops you into a scripted high-stakes scene — negotiating a raise, delivering tough feedback, calming an angry enterprise customer, holding a boundary with a parent — and has you type what you'd actually say to an AI persona that pushes back in character. Mission Mode tracks live meters like anger, trust, or guilt pressure that shift with your responses, and 33 personas (Musk, Jobs, Trump, Buffett, Socrates) each reason differently rather than following one chatbot script. It's free to start, with no signup required.

- −Practice is text-only — no voice or video mode to rehearse tone and delivery
