Which AI assistants send you humans?
AI isn’t only crawling you. It’s referring visitors. Lume measures the human traffic AI assistants send, even when the referrer is stripped.
The visitors AI sends you
Lume tracks 15 AI assistants across 18 referrer domains (ChatGPT, Claude, Gemini, Perplexity and more) so you can see the humans arriving from AI answers.
Detection that survives stripped referrers
AI apps often send visitors with no referrer or bucket them as “Direct.” Lume detects AI referrals by referrer host and by utm_source, catching traffic client-side analytics quietly loses.
Referrals vs. crawls: both matter
A crawler indexing your content and a human arriving from an AI answer are two different things. Lume keeps them separate: one is the machine reading you, the other is the visit it sent back.
FAQ
Why can’t I see AI traffic in my normal analytics?
Many AI apps strip the referrer or pass none at all, so those visits land in “Direct.” Lume detects them server-side by referrer host and utm_source instead of relying on a referrer that isn’t there.
Is an AI referral the same as an AI crawler?
No. A crawler is a bot reading your site; an AI referral is a human who clicked through from an AI answer. Lume measures both, separately.
Which AI assistants are tracked?
