CosVoice

What It Is

CosVoice gives your AI assistant — whether it's Grok Bot, Claude, ChatGPT, or Muse — its own phone number. The same Chief of Staff that runs your day on your computer can now make calls, take calls, and send you written summaries of every conversation. It's designed for people who need their AI to handle phone-based errands: booking restaurant tables, taking contractor callbacks, ordering food, managing voicemail, and more.

Who It's For

CosVoice serves individuals who rely on AI assistants for daily task management, as well as small businesses that need an intelligent phone presence — home services, salons, retail shops, restaurants, auto shops, real estate offices, and professional services. If you've ever wished your AI could just pick up the phone and handle an errand while you're driving or in a meeting, CosVoice is built for that moment.

Key Features & Capabilities

• Three-Way Calling System: Call your assistant for instructions, have it make outbound calls on your behalf, or let it answer inbound calls when you're unavailable
• Written Summaries: After every call, receive a concise summary in your inbox and your assistant's chat with key details, decisions, and next steps
• Deep Integrations: Works with 23+ services including Instacart, Uber Eats, DoorDash, OpenTable, Resy, Tock, Google Calendar, Gmail, Calendly, Zoom, Uber, and more
• One-Paste Connection: Integrates with your existing AI assistant (Grok Bot, Claude, ChatGPT, Cursor) via a single MCP server URL — no API keys to manage
• Dedicated Email Address: Each number comes with its own email (yourname@bot.cosvoice.com) that your assistant can read and respond from
• Instant Wake-Up: Text the line and CosVoice immediately starts your assistant with the task in hand — no polling or delays
• Real Phone Calls: For services without APIs (most restaurants, local businesses), your assistant literally picks up the phone and talks to a human

How It Works

You choose a number in your area code and save it as a contact. When you call or text, your assistant recognizes your number and takes instructions. You can ask it to "book us a table Friday at 7:30" and it will call the restaurant, negotiate the time, and book under your name. When the plumber calls back, your assistant asks about pricing, timelines, and what's included — then sends you a structured summary with amounts, dates, and decisions waiting on you. Voicemail becomes obsolete: forward missed calls to your assistant and get real notes instead of "please call back."

What Sets It Apart

Unlike dial tone services or call centers, CosVoice is purpose-built as a desk for your existing AI assistant. It doesn't replace your assistant — it gives it a phone. The focus is on finished work: complete errands, captured details, and decisions extracted from conversations, not just call logs or transcripts. It's one line, one assistant, one call at a time, designed for the person (or small business) your assistant works for.
