You know what you want to say. You've rehearsed it in your head a hundred times. But when you're in the room - your mind goes blank. Assertr is an AI voice coach that lets you practice difficult conversations out loud before they happen. Not typing. Speaking. The way real conversations actually work. WHAT YOU CAN PRACTICE: - Salary negotiation - 57% of workers never ask. 2/3 who do, get the raise - Tough feedback - be honest without burning bridges - Job interviews - answer hard questions under pressure - Speaking up in meetings - stop being the quiet one - Difficult boss conversations - navigate what you've been avoiding - Setting boundaries - say no without guilt - Team conflict - resolve disputes with clarity - Offer negotiation - maximize your compensation WHY VOICE, NOT TEXT: You already know ChatGPT can role-play in text. But real conversations aren't text. They're voice, pressure, emotions, and someone going off your carefully prepared script. Assertr puts you in the conversation. Out loud. So when the stakes are real - you've already been there. HOW IT WORKS: 1. Pick a scenario or describe your own 2. Have the conversation out loud with AI 3. Get scored on 5 dimensions: clarity, confidence, empathy, assertiveness, strategy 4. See exactly where you went off track 5. Practice again until you're ready THE MATH: One successful salary conversation = $5,000-$15,000/year. One Assertr session = 10 minutes. You already spend hours overthinking it. Spend 10 minutes practicing instead. BUILT FOR THE NIGHT BEFORE: Got a performance review tomorrow? A tough conversation you keep postponing? Assertr is available at 11pm - when the anxiety peaks and a human coach isn't. Track your growth across sessions. Build real communication skills. Turn deep conversations into career breakthroughs. Stop overthinking. Start practicing. Terms of Use (EULA): https://assertr.app/legal/terms/ Privacy Policy: https://assertr.app/legal/app-privacy/

Find your words before the real conversation. An interview tomorrow. A difficult conversation at work. A first hello that feels harder than it should. Talksim gives you a place to rehearse with an AI partner, get specific feedback, and try again at your own pace. 62 REAL-LIFE SCENARIOS Practice small talk, workplace discussions, interviews, service encounters, friendships, dating, family conversations, and complaints. Every built-in scenario is available in English and Japanese. Each gives you a situation, an AI conversation partner, and a clear goal. Try situations such as: โ€ข Breaking the ice with a new coworker โ€ข Telling your manager a task is behind schedule โ€ข Saying no when you already have too much work โ€ข Asking your own questions in an interview FIVE SKILLS. SPECIFIC FEEDBACK. See your overall score and feedback on clarity, empathy, listening, topic development, and politeness. Review what worked, what to improve, and examples of stronger wording. Compare with your personal best, then try the conversation again. A NEW CHALLENGE EVERY DAY The weekly league gives everyone in each language the same daily challenge. Your best score each day counts; your five highest daily scores form up to 500 League Points. English and Japanese have separate rankings. Anyone can view the league. Submitting ranked scores requires a Lite or Studio subscription, Sign in with Apple, AI-processing consent, and enough AI Credits. You can complete up to three ranked evaluations per UTC day. Scores are shown with an anonymous player code, not your conversation. SEE YOUR PRACTICE OVER TIME Revisit past conversations, follow your score history, and see how your five skills compare. Practice again whenever you want to prepare for a similar situation. PRIVATE, ON-DEVICE PRACTICE On compatible devices with Apple Intelligence enabled and available, regular on-device practice is free. Conversation text stays on your device in this mode. AI availability depends on your device, language, and system settings. OPTIONAL CLOUD AI Studio Uchu AI is optional and requires a membership and consent to cloud processing. Lite includes 800 AI Credits and Studio includes 4,500 AI Credits per subscription period. Credits are consumed according to the actual AI processing cost, so usage varies by conversation and evaluation. Credits are shared across supported Studio Uchu apps; use the same Sign in with Apple account to access your shared membership. When you choose cloud AI, the necessary conversation content is sent for processing. The weekly league stores an anonymous display code, scores, challenge information, and submission times; it does not publish your conversation text. See the Privacy Policy for processing details. AI replies and scores can be inaccurate. Scores are practice feedback, not a professional assessment. Talksim is not a therapy or medical service. Subscriptions renew automatically unless cancelled. Manage or cancel in your App Store account settings.
