What is Simple AI?

Simple AI is a voice AI platform that lets you build, deploy, and manage AI-powered phone agents. Your agents can make outbound calls, answer inbound calls, send and receive SMS, and be embedded directly in your website — all from a single platform.

​
What You Can Build

  • Outbound calling agents that reach contacts with personalized conversations
  • Inbound support agents that answer calls on your phone numbers 24/7
  • SMS agents that hold text conversations alongside voice
  • Web chat agents embedded in your website via the web widget
  • Outbound campaigns that contact lists of recipients at scale with retry logic and scheduling

​
How It Works

  1. Create an agent — define the personality, prompt, tools, and knowledge your agent needs. Use a simple prompt for quick setups, or build a multi-step flow for complex scenarios. See Agents.
  2. Connect a phone number — buy a number through Simple AI or bring your own via SIP integration. See Phone Numbers.
  3. Make calls — trigger outbound calls through the API, the dashboard, or campaigns. Attach agents to numbers for inbound calls.
  4. Analyze results — use analyzers, tags, and sentiment analysis to extract structured insights from every conversation.
  5. Integrate with your systems — connect tools so agents can look up data, update records, and take actions during calls. Use webhooks to push real-time call events to your application.

Quick Start

The fastest way to get started is to create a call with an inline agent using the API: 
curl -X POST "https://api.usesimple.ai/api/v1/calls" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to_number": "+15551234567",
    "from_number": "+15559876543",
    "prompt": "You are a friendly assistant calling to confirm an appointment."
  }'
You can find your API key in the Simple AI dashboard under Settings > API Keys. For more control, create a reusable agent first and then reference it by ID when making calls. See the API reference for the full set of endpoints.
