ChatGPT & Claude (MCP)
How to Call and Text People with ChatGPT and Claude
Claude and ChatGPT can call and text people for you once they're connected to an AI phone agent in Carly. Ask Claude to call someone and find out what you need, like whether they're free for lunch next week at the times you offer. You can steer the call while it's happening by typing to Claude, or have it text people and handle the whole back-and-forth. When they reply, it books the meeting and lets you both know. Setup takes about 10 minutes: create the agent on Carly's Agents tab by describing what it should do, get it a phone number, give it a voice, then paste Carly Teams' setup prompt into Claude or ChatGPT. It works with Grok too.

Ask it to call or text someone
Try "Call Joe and ask if he's free for lunch next week. I'm open Tuesday at 11:15 or Wednesday to Friday between 11:30 and 2:30." Type to Claude during the call to steer it, or ask it to text someone and book a 30-minute call when they reply.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
