12 AI engines tracked
The pixel recognizes traffic from every major AI platform: ChatGPT (including chat.openai.com), Perplexity, Gemini (including Bard), Copilot (including Bing Chat), Grok (including X/Twitter integration), You.com, Meta AI, Poe, Phind, Mistral (including Le Chat), and more. Each engine is tracked separately with its own visit counts, conversion rates, and revenue attribution.
How does the pixel detect AI visitors?
Not all AI traffic carries a referrer header. ChatGPT added utm_source=chatgpt.com to outbound links in June 2025, but many engines still strip referrers entirely. The pixel uses two approaches:
- HTTP Referrer — primary method. Matches the document.referrer against 19 known AI domain patterns. Fastest and most reliable when available
- UTM parameters — fallback. Scans utm_source in the URL query string against both full domain names and short aliases (e.g., “chatgpt”, “perplexity”, “gemini”). Catches traffic that other analytics tools miss entirely
If neither method detects an AI source, the script exits immediately without sending any data. No tracking of non-AI visitors.
