Overview

CosVoice is a service that adds a real US phone number with a local area code, plus a dedicated email inbox, to the AI assistant you use today. Through the assistant, it can phone restaurants, tradespeople and offices on your behalf, pick up calls to that number, and send a written summary of each call to your inbox. The site lists support for ChatGPT, Claude, Grok Bot, Cursor and other assistants that use MCP. According to the site it admits to being an AI if asked, will not share payment card details, and saves a complete transcript of each call. It places real calls to businesses for you, so check your local rules on AI calls and call recording.
