What analytics tools show traffic coming from ChatGPT and Perplexity?
What analytics tools show traffic coming from ChatGPT and Perplexity? GA4, Promptwatch, LLM Pulse, Foglift, Known Agents and more compared on what they actually measure.
Traffic from ChatGPT and Perplexity is easy to undercount. Some visits arrive with a referrer you can read, some arrive with none, and many AI answers never produce a click at all. So the useful question is not just "which tool shows the number" but "what does the number include, and what is it missing?"
There are three kinds of tools that touch this: general web analytics, dedicated AI traffic attribution, and AI crawler analytics. They answer different questions, and confusing them leads to bad reports. Promptwatch is the one that covers the most of them in one place, so it leads the comparison below.
Three things people call "AI traffic"
1. Referral visits. A person clicks a link in an AI answer and lands on your site. This is the traffic that analytics tools can attribute to ChatGPT, Perplexity, Gemini and others, subject to referrers being passed.
2. Crawler hits. A bot such as GPTBot, OAI-SearchBot, ChatGPT-User or PerplexityBot fetches your page. This is not a visitor, but it is a precondition for being cited, and it shows up in server or CDN logs, not in web analytics.
3. Mentions without clicks. The answer names your brand and nobody clicks. No analytics tool sees this. Only prompt tracking does.
A complete picture uses all three. Most "AI traffic" dashboards cover only the first.
1. General web analytics (GA4 and similar)
GA4 can show sessions by source, so visits from chatgpt.com or perplexity.ai may appear as referral traffic, depending on what the platform passes. You can build a custom channel group that collects the known AI referrers. This costs nothing and is a good first step. The limits are real: you must maintain the referrer list yourself, visits with no referrer land in direct traffic, and GA4 knows nothing about prompts, citations or crawlers. It tells you a visit happened, not why.
2. Promptwatch
Promptwatch's visitor analytics counts AI-referred traffic and conversions, covering ChatGPT, Perplexity, Gemini, Claude, Copilot, DeepSeek, Kimi, Mistral and more, through a lightweight script, a GTM template or the WordPress plugin. Because it also holds prompt tracking and citation data, you can connect a visit to the citation that probably produced it, rather than guessing.
On the crawler side, Agent Analytics logs AI bots in real time, with IP verification so spoofed user agents are filtered out, and a crawl-to-citation path with a citation rate per page. 360 Insights joins crawler logs, citation clicks and AI-referred visits for each page. Search Insights adds Google Search Console and Bing Webmaster data, including Microsoft Copilot traffic.
Plans: free Explore, Essential ($95 a month, includes 200K visitor events), Professional ($245, 1M events and 25M crawler logs), Business ($579). Crawler logs start on Professional. A published case study from TreeHouse (Pararius and Huurwoningen.nl) reports that AI search became about 25% of their organic conversions, 99% of it from ChatGPT, after fixing crawler access. That is one customer's result.
3. LLM Pulse
LLM Pulse lists AI traffic analytics among its features, from its Growth plan (€99 a month on weekly tracking) alongside sentiment and owned-media tracking. It is a focused tracker with unlimited seats and an MCP server on every plan.
4. Foglift
Foglift includes AI Crawler Analytics and a referral tracker on every plan, including its free tier. Paid plans start at $49 a month and meter monitoring in tokens. It is a cheap way to see both crawler activity and referrals.
5. Known Agents
Known Agents focuses on Agent Analytics: visits by agent, category and page, spike alerts, error and redirect analysis, robots.txt violations and spoof verification, plus AI chat referral tracking of human visits. It has a free plan and paid plans from $29 a month. It suits teams who mainly want the traffic side without prompt tracking.
6. AthenaHQ
AthenaHQ lists GA4, Shopify and Webflow revenue attribution among its features. Starter is $295 a month. It makes sense if you want attribution tied to an action workflow, though crawler logs are not published.
7. Cloudflare AI Crawl Control
Cloudflare AI Crawl Control is included free on every Cloudflare plan and shows crawler activity. Referral data needs a paid plan, Pro from $20. It is a good free first look at crawlers if your site runs on Cloudflare.
8. SEO suites
Ahrefs and Semrush added AI modules that report on brand mentions and cited sources. Ahrefs Brand Radar also reports on AI crawler activity. Neither is a replacement for measuring actual visits on your own site, so check what the module attributes before relying on it.

Who should pick which
You want to see visits, crawlers, citations and prompts in one place: Promptwatch.
You want a free starting point: GA4 with a custom channel group, plus Cloudflare crawler data if you are on Cloudflare.
You want a cheap tracker with crawler and referral views: Foglift.
You only care about bots and robots.txt: Known Agents.
Reading the numbers honestly
AI referral traffic is often small next to organic search, and some of it hides inside direct traffic. A low number does not prove a low impact: buyers can see your brand in an answer and search for you later. Treat the traffic numbers as a floor, track trends over weeks, and pair them with prompt tracking so you can see what the engines say before anyone clicks.
