# Smitline

> Smitline lets AI agents such as Claude and ChatGPT make phone calls and join Zoom, Microsoft Teams and Google Meet meetings for you, with everything the agent already knows about you and the task. Your agent follows the call live, steers it and can do work while it runs, then gets back what was said and agreed. It connects to your agent as one MCP server for both calls and meetings. Smitline is made by Kaelor Labs.

Smitline comes in two forms:

- **Smitline Cloud** is the hosted service at https://smitline.com. Connect your agent with one link and sign in; no phone or AI accounts to set up, and nothing to keep running. It is in private beta: ask for early access at https://smitline.com/early-access.
- **The Smitline engine** is open source (Apache-2.0) at https://github.com/kaelorlabs/smitline. Run it yourself in Docker with your own OpenAI and SignalWire or Twilio accounts.

## Self-hosted or Smitline Cloud

| | The Smitline engine (self-hosted) | Smitline Cloud (hosted) |
| --- | --- | --- |
| Where it runs | In Docker on your computer (Docker Desktop on Mac or Windows, Docker Engine on Linux) | On Kaelor Labs' servers; nothing to keep running |
| Accounts you need | Your own OpenAI API key with access to GPT-Live, and a SignalWire or Twilio account | None: an invite during the private beta |
| Caller ID | Your own number, through your SignalWire or Twilio account | A shared Smitline number, or a dedicated number of your own (optional) |
| Your data | Keys, call records and transcripts stay on your computer | Briefs, transcripts and summaries stay in your account |
| Cost | Free software; you pay OpenAI and your phone provider directly | Pay as you go from prepaid credit: $10 covers about 50 minutes of phone calls; no subscription |
| Get it | https://github.com/kaelorlabs/smitline (setup guide: SETUP.md) | https://smitline.com/early-access |

Both run the same engine, with a real-time voice from OpenAI's GPT-Live and the same guardrails.

## Questions people ask

### What is Smitline?

Smitline lets AI agents such as Claude and ChatGPT make phone calls and join Zoom, Microsoft Teams and Google Meet meetings for you, or start a meeting room and send people its link, with everything the agent already knows about you and the task. Your agent follows along live, steers the conversation and can do work while it runs, then gets back what was said and agreed. It connects to your agent as an MCP server. Smitline is made by Kaelor Labs (https://smitline.com/about): Smitline Cloud is the hosted service, and the engine is open source.

### Which AI agents does it work with?

Any agent that can use an MCP server, such as ChatGPT, Claude, Grok, Perplexity, Claude Code and Cursor, and agents like Meta Muse that connect to a REST API. You add Smitline as a connector with one link and sign in, with no phone or AI accounts to set up. The link is https://app.smitline.com/mcp. During the private beta, signing in needs an invite. Steps for each: Works with (https://smitline.com/works-with).

### Can ChatGPT make phone calls?

Not on its own. With Smitline, ChatGPT can make real phone calls for you: on any ChatGPT plan, add Smitline as a custom MCP server under Plugins on the ChatGPT website, sign in, and ask ChatGPT to call. Setup steps for ChatGPT (https://smitline.com/works-with/chatgpt).

### Will they know it’s an AI?

Yes. It opens by saying whom it’s calling for, why, and that it’s their AI assistant, and says so again before it hangs up. Anyone who asks gets a straight answer. In meetings it introduces itself when it joins.

### Can it get through phone menus and wait on hold?

Yes. Smitline listens to an automated phone menu, presses the option that fits and keys in a number you give it for that call, such as an account or order number. It never keys in card numbers, PINs or passwords. If it’s put on hold, it waits, up to an hour by default, and can ring you when a person picks up.

### What can’t it do?

It calls only US and Canadian numbers for now, with more countries on the way, and leaves a short voicemail if no one answers. Smitline Cloud is for adults in the US and Canada, and isn’t offered to residents of Quebec for now.

### How much does Smitline cost?

Smitline is pay as you go: you add credit in advance, from $10, and calls use it by the second while they’re connected. $10 covers about 50 minutes of phone calls, or about 80 minutes in meetings. There’s no subscription, and ringing, busy and unanswered calls are free. More on the pricing page (https://smitline.com/docs/pricing).

### Is it okay to have an AI call for me?

It’s upfront about being an AI, calls only from 8 AM to 9 PM their time unless you say they expect your call then, never calls emergency, crisis or premium-rate numbers, and respects do-not-call requests. You’re responsible for what you ask it to do, including any consent rules that apply to you.

### Can I run Smitline myself?

Yes. The Smitline engine is open source under the Apache-2.0 license, at github.com/kaelorlabs/smitline, and listed in the official MCP Registry as io.github.kaelorlabs/smitline. Running it yourself takes Docker and your own OpenAI and SignalWire or Twilio accounts; Smitline Cloud runs the same engine for you.
