Introduction - Simple AI

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

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.
Connect a phone number — buy a number through Simple AI or bring your own via SIP integration. See Phone Numbers.
Make calls — trigger outbound calls through the API, the dashboard, or campaigns. Attach agents to numbers for inbound calls.
Analyze results — use analyzers, tags, and sentiment analysis to extract structured insights from every conversation.
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.

Key Concepts

Concept	What It Does
Agents	Define how your AI behaves — prompt, voice, tools, and conversation flow
Calls	Inbound and outbound voice conversations handled by your agents
Phone Numbers	Numbers your agents use to make and receive calls
Campaigns	Batch outbound calling with scheduling, retries, and goal tracking
Tools	API connections that let agents interact with external services during calls
Knowledge Base	Reference material your agents can access during conversations
Analyzers	Post-call analysis that extracts structured data from transcripts
Tags	Labels for organizing and filtering calls by outcome or topic
Webhooks	Real-time event notifications pushed 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.
