CosVoice: a real phone number and email for your AI assistant

About CosVoice

CosVoice turns the AI assistant you already use into something that can make phone calls. It gives your assistant a real US phone number in your area code and its own email address. You call it or message it with an errand, and it phones the restaurant, contractor or office for you, then sends a written summary of the call to your inbox. It can also answer calls when you cannot, and people can email it directly.

The homepage demo shows the idea: an assistant called Lloyd phones a restaurant to book a table for two on Friday at 7:30, accepts 8:15 when 7:30 is full, and later takes a call from a plumber, with both calls written up afterwards. It connects to Grok, ChatGPT, Claude, Cursor and any assistant that supports MCP, and developers get a REST API and signed webhooks. There are also pages pitching it as an AI receptionist for small businesses such as salons, auto shops and home services.

It is priced like a phone line, with plans differing only in call minutes. The pricing page lists Starter at $29 a month for 100 minutes (about 25 calls) and Plus at $79 a month for 300 minutes, with a larger tier above. A seven-day trial with 10 minutes of calls is free, but a card is needed to start and Starter is charged on day seven unless you cancel.
