# Platforms Monitored

> FAII monitors 5 major AI chatbot platforms - ChatGPT, Claude, Perplexity, Grok, and Gemini. Understand what each platform offers and why coverage across all matters.

<Info>
  **Quick Answer:** FAII monitors ChatGPT, Claude, Perplexity, Grok, and Gemini. Each platform has different user bases and recommendation patterns, so visibility on one doesn't guarantee visibility on others.

## Platform Overview

| Platform       | Company       | Model             | Weekly Users | Key Strength                 |
| -------------- | ------------- | ----------------- | :----------: | ---------------------------- |
| **ChatGPT**    | OpenAI        | GPT-5             |     100M+    | Largest user base            |
| **Claude**     | Anthropic     | Claude 3.5 Sonnet |     30M+     | Professional/business use    |
| **Perplexity** | Perplexity AI | Sonar             |     15M+     | Search with citations        |
| **Grok**       | xAI           | Grok-3            |     20M+     | Real-time social signals     |
| **Gemini**     | Google        | Gemini 2.5        |     50M+     | Google ecosystem integration |

## Why All 5 Matter

Different platforms recommend different brands for the same query. Testing shows:

* A brand mentioned on ChatGPT may be absent from Claude
* Perplexity tends to favor brands with strong web citations
* Grok incorporates social sentiment that others ignore
* Gemini's recommendations often align with Google search data

**Your visibility is only as strong as your weakest platform.**

## Reading Cross-Platform Data

The Chat Intelligence dashboard shows a **platform heatmap** that reveals:

* Which platforms mention you (green) vs. don't (red)
* Your average position on each platform
* Sentiment differences across platforms
* Keywords that work on some platforms but not others

This cross-platform view is critical for identifying where to focus improvement efforts.
