# CosVoice > CosVoice gives a Chief of Staff AI agent (a Grok Bot, or any agent that speaks MCP) its own real phone number in the owner's area code and its own email address (handle@cosvoice.com). The owner calls or texts the line when away from the desk; the line answers as the assistant in a natural full-duplex voice, runs an intake instead of taking a message, places calls on the owner's behalf (restaurant reservations, vendor callbacks, appointments), handles callbacks, and sends a written debrief (summary, outcome, structured details, transcript) after every call. Tagline: "Give your CoS a voice." Differentiator: every Grok Bot gets its own line. ## Key facts - One line = one phone number + one email address, attached to one AI Chief of Staff. - Voice: Grok Voice (xAI), full-duplex speech-to-speech; the line always says it is an AI assistant when asked and never pays or reads out a card. - Inbound: intake, not voicemail (who, what, amounts, dates, options, reference numbers, deadline, next step). Approved/VIP/blocked contact roles; the owner's mobile is the "owner line" whose calls and texts are instructions. - Voicemail replacement: forward missed calls from your own mobile to the line (carrier conditional forwarding); the line answers as your assistant covering the phone, and the debrief is tagged "Missed on mobile". - Outbound: restaurant reservations by phone (OpenTable, Resy, Tock, and DoorDash offer no third-party agent path), appointments, vendor and logistics callbacks. - Agent access: remote MCP server at https://cosvoice.com/mcp (Authorization: Bearer ), REST API at https://cosvoice.com/api/v1, signed webhooks (call.completed, message.received, email.received). Works with Grok Bot, Claude, ChatGPT, Cursor, OpenClaw. - Dashboard: unified history of calls, texts, and email with notes and CSV export; email forwarding to any inbox. ## Pricing (USD) - Starter: $29/month, 60 minutes of calls included, then $0.25/minute. - Plus: $69/month, 200 minutes of calls included, then $0.25/minute. - Pro: $149/month, 600 minutes of calls included, then $0.25/minute. - Founding members: Plus for $49/month locked for 12 months (limited). ## Integrations - Live through the MCP gateway: Instacart, Uber Eats, Google Calendar, Gmail, Calendly, Zoom, Uber, Kiwi.com flights, Shopify stores. - Live by phone (the line calls them): DoorDash, OpenTable, Resy, Tock, Pharmacy callbacks, Airlines & hotels, Home services. - Coming: Yelp, Booking.com, Kroger, Zocdoc, Google Maps, Ticketmaster, UPS. ## Pages - Home: https://cosvoice.com/ - How it works: https://cosvoice.com/how-it-works - What people use it for: https://cosvoice.com/use-cases - Replace your voicemail (carrier codes): https://cosvoice.com/voicemail - For Grok Bot (setup in one paste): https://cosvoice.com/grok-bot - Integrations: https://cosvoice.com/integrations - Pricing: https://cosvoice.com/pricing - Trust and safety: https://cosvoice.com/trust - FAQ: https://cosvoice.com/faq - Docs (MCP tools, REST, webhooks): https://cosvoice.com/docs - Privacy: https://cosvoice.com/privacy ยท Terms: https://cosvoice.com/terms - Full detail: https://cosvoice.com/llms-full.txt
