AI Voicemail & Call Screening

Someone calls while you're busy. Your AI assistant answers, has a real conversation with the caller, and sends you a transcript and summary. You never miss what matters - even when you can't pick up.
AI Voicemail & Call Screening uses AI to screen incoming calls, transcribe voicemails, and block spam - so you're always in control of your calls.
✦ WHAT IT DOES
🤖 AI Answers Your Missed Calls
Your personal AI assistant picks up when you can't. It has a natural conversation with the caller, takes their message, and tells them you'll call back. You get a full transcript and AI summary - not just a missed call notification.
📝 Voicemail to Text
Every voicemail is transcribed instantly - voicemail to text, on your screen in seconds. No more dialing into a voicemail box. AI summarizes long messages so you see what matters at a glance. Fastest voicemail transcription on Android.
🛡️ AI Call Screening
AI screens calls intelligently. Spam, robocalls, and unwanted callers are handled automatically. Urgent calls are flagged so you know what needs attention.
📊 Smart Call History
Every call is auto-categorized - Business, Personal, Spam, or Urgent - with an urgency score. Browse your full call log with transcripts, summaries, and caller details in one place.
🔄 Works in the Background
Uses your carrier's built-in call forwarding. No battery drain. No background process. Dial a code once and AI handles every missed call from that point on.
🤝 Smart Voicemail Assistant
This isn't a basic voicemail box - it's a smart voicemail assistant that holds real conversations, understands caller intent, and gives you actionable summaries. AI call answering that actually works.
🎭 Customizable AI Personality
Choose how your AI sounds: Professional, Friendly, Concise, or Empathetic. Each style changes how your assistant greets callers and handles conversations.
