# Understanding LLM Referrals

See how many visitors come from AI assistants like ChatGPT, Perplexity, Claude, and Gemini.

When someone clicks a link to your site inside an AI assistant's answer, Humblytics records it as an LLM referral. LLM stands for large language model, the technology behind tools like ChatGPT. Nothing extra needs to be set up, because your existing tracking script detects these visits.

Go to **Observe → Analytics → More → LLM Referrals**.

## What you'll see

| Item             | What it means                              |
| ---------------- | ------------------------------------------ |
| **Total Visits** | Visits that came from any AI assistant.    |
| **LLM Sources**  | How many different AI tools sent visitors. |
| **Top Source**   | The AI tool sending the most visitors.     |

A donut chart shows each tool's share, and the **All LLM Sources** table lists every tool with its **Visits** and **Share**.

Humblytics detects ChatGPT, Perplexity, Claude, Gemini, Copilot, and other AI assistants, and adds new ones as they appear.

## What to do with it

* **Track AI visibility.** Rising LLM visits mean AI tools are recommending you more often.
* **See what they recommend.** Filter the Pages tab by **Referral** to see which pages AI tools link to, then keep those pages accurate and up to date.
* **Compare quality.** Use the **Filter** menu to view only AI traffic, then check its bounce rate and conversions against search traffic.
