intermediate

The Rundown

In this guide, you’ll build an AI personal assistant that you can call from your phone. It will know your calendar, your business, and any additional context you add to its knowledge base. The setup takes about 10 minutes and costs $0 to test.

Who This Is Useful For

  • Busy founders or operators who want a hands-free way to check their schedule.
  • Consultants juggling multiple clients who need quick access to project information on the go.
  • Anyone who wants to experiment with voice AI agents without writing code.

What You Will Build

You’ll create a personal AI phone assistant powered by ElevenLabs that answers calls, uses your calendar and business context, and can later be extended with tools like webhooks and automations.

  • An ElevenLabs personal assistant agent.
  • A Twilio phone number connected to the agent.
  • A knowledge base with your calendar, business page, or other static context.
  • An optional path for adding live integrations later.

What You Need

  • ElevenLabs account. The free plan works.
  • Twilio account. It is free to sign up and includes $15 in credits.
  • A calendar export or text file with your schedule.
  • Optional: a URL to your business or product page.

Going Further

  • After the basic assistant is working, you can add tools and integrations for live calendar access, CRM lookups, advanced integrations, or webhooks connected to Make.com, n8n, or Zapier. With webhooks, your assistant can pull live calendar events, schedule meetings, check email, or look up client information from a phone call.
The knowledge base is static, so use it for information that does not change often. For dynamic data like live calendar events, use webhooks.
