It can send SMS, iMessage and WhatsApp messages from your Dial numbers, search messages and calls, and place a phone call handled by Dial's AI voice agent. It can also look up a phone number and show your usage.

Questions

What can the AI do in Dial?

The AI can read your account, numbers, contacts, group chats, messages, calls and usage, and look up phone numbers. It can send messages, reply to messages, place AI voice calls and update a number's settings, including the AI agent's inbound instructions.

Does the AI see my Dial API key?

No. Your Dial credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with searching messages and calls. Sending a message and placing a call reach real people, and calls may incur charges, so these tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Dial account.

Why do I need the Dial CLI to get an API key?

Dial issues API keys through its command-line tool. You sign in with your email, enter the one-time code, and the CLI prints an sk_live_ key once. Paste that key into HeyMyApps.
