Conversation is coming. Be ready. Say the hard thing. Get scored. Nerve Arena is where you practice difficult conversations before they happen. Fight AI personas who push back exactly like difficult people do, and a judge scores every reply on six stats. SAY IT OUT LOUD Voice AI lets you speak your side out loud in real time, and the same judge scores every reply as you go. Your first voice fight is free; after that, pay per fight with coins you earn by training, or take Nerve Pass Pro with five voice fights a day included. WHAT MAKES IT DIFFERENT Anything can role-play a difficult person. Nerve Arena scores every reply you give on six communication stats, so you can see yourself actually getting better, not just feel good for a turn. The personas fight back: they deflect, gaslight, escalate, and play the victim, exactly the way the real ones do. HOW IT WORKS 1. Pick a persona and a scenario, then have the conversation, typed or out loud. They stay in character. 2. Your first fight reads your communication style, so training starts from your actual gaps. For your first three fights, in-fight coaching is free too. 3. A Gemini-powered judge scores every reply across six stats: Boundaries, Clarity, Empathy, Composure, Patience, Rapport. 4. Watch the replay, see where you cracked, and train until the moves are automatic. THE PERSONAS A growing roster of AI personas, each a different kind of hard: the Gaslighter twists your words, the Credit-Stealer takes your ideas, the Guilt-Tripper weaponizes every favor, the Interrupter won't let a sentence land, the Diplomat commits to nothing and more. Can't find the one who gets under your skin? Build your own in Forge. Each fight sets its own difficulty on the stance screen, up to Nightmare. BUILT FOR - The professional who thinks of the right line after the meeting ends: train your assertiveness and leadership communication - The boundary-setter dreading the next family call: train boundary setting against the exact persona pulling you back in - Anyone who has ever lost a conversation they didn't even know they were in GO DEEPER - Campaigns: structured runs across work, family, and relationships that escalate as you go - Forge: build your own persona and scenario, then share them with the community - Daily Spark: a fresh scenario every day - Field Journal: log the real conversations, and the AI shows you the stats inside them - Rivalry and Ranking: fight a friend's scenario, or join the leaderboard WHAT IT IS NOT Not therapy. Not a course. Not a chatbot. If you're working through something serious, please talk to a professional. This app is a conversation practice tool, built to be the rehearsal, not the resolution. NERVE PASS (optional) Free: 3 daily Resolve (the stamina that gates a fight), the full persona roster, the full scoring loop, and your first voice fight. Nerve Pass: 12 daily Resolve, in-fight coaching, Advanced Insights, 3 persona generations a week, a monthly stat respec. Nerve Pass Pro: everything in Pass, five Voice AI fights a day included, Nightmare difficulty, custom stances, effectively unlimited Resolve. FREE TRIAL Nerve Pass and Nerve Pass Pro, monthly or annual, each start with a 7-day free trial for eligible new subscribers. After the trial, the plan renews automatically at its regular price, shown in the app before you subscribe, and is charged to your Apple Account. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends, the trial included; manage or cancel anytime in your Apple Account settings. Everything free stays free. PRIVACY We don't sell your conversations. We don't train external models on them. Full policy at nervearena.com/privacy Train for the conversations you've been avoiding.
