Murmur is a private way to practice phone calls with realistic AI. If you hate calling doctors, offices, customer service, landlords, recruiters, or anyone you don't know, you're in the right place. A lot of us grew up texting everything. So when it's time to actually make a call, the brain just goes blank. Murmur lets you run the whole conversation first - you talk out loud, the AI talks back, and you rehearse the exact call you're scared to make. Most AI voices read at you. Murmur's coach speaks - intonation, pauses, and tone that shifts with the conversation. WHAT YOU CAN PRACTICE - Mock interviews with follow-up questions - Asking about a job application - Calling a doctor or clinic - Booking appointments - Talking to your landlord - Handling customer service - Returns, refunds, awkward conversations - Any scenario you write yourself FEATURES - A coach that sounds human - intonation, pauses, and emotion - 40+ scenarios across many categories, and you can write your own - 3 difficulty levels with different personalities and tones - Notes after every call - what worked, what to try next time - Rehearse in French, Spanish, German, and more - the coach picks up your language and switches with you - Breathing exercises to settle yourself before the real call - Your voice is never recorded or stored - streamed live during the call WHY IT HELPS Most phone anxiety comes from not knowing what the other person will say. Murmur lets you hear it ahead of time. Practice until the call stops feeling like a big deal. SUBSCRIPTION Try Murmur free. Upgrade for unlimited calls, interview prep, and advanced roleplay options.
