Knowing ChatGPT sends you visitors is the easy part. Chartsy shows whether they sign up, pay, and what they're worth.
More buyers now ask ChatGPT, Perplexity or Claude which tool to use, then click through. Most analytics tools can show those visits. What they can't show is what happens next: which of those visitors signed up, which became paying customers in Stripe, Paddle, Freemius, Polar.sh, Creem.io or Lemon Squeezy, and how much MRR they bring today. Chartsy recognises AI assistant traffic automatically and follows it through to revenue.
ChatGPT visits arrive either with chatgpt.com as the referrer or with utm_source=chatgpt.com added to the link. Analytics tools like GA4 show them as a referral source. To know whether that traffic is worth anything, you also need to track signups from those visits and match them to your billing account, so ChatGPT shows up next to paying customers and MRR - not just sessions.
AI assistant traffic is small next to search, so it's easy to dismiss on visits alone. But people who arrive from an assistant's recommendation may already have compared options and be ready to buy - and a visit count can't tell you whether they are.
The only way to know is to follow those visitors past the visit: to the signup, to the first payment, and to whether they're still paying. That needs your website tracking and your billing data in the same place.
Real numbers from a SaaS that tracks its revenue with Chartsy (anonymised):
104 visits is a small number next to search traffic. But every signup from ChatGPT became a paying customer - something a visit count alone would never show.
The questions that decide whether to invest in being recommended by AI assistants, and what the numbers said:
How much traffic does ChatGPT send?
104 visits, recognised automatically from the chatgpt.com referrer or the utm_source=chatgpt.com tag ChatGPT adds to links.
How many of those visitors signed up?
8 signups - about 7.7% of ChatGPT visits.
Did they become paying customers?
All 8 did. Every signup that came from ChatGPT is a paying customer.
What are they worth?
$759 in MRR today - about $95 a month per customer, or roughly $7.30 of MRR for every ChatGPT visit.
Is it worth working on being recommended by ChatGPT?
For this site, yes. A channel where every signup pays is worth growing, even at a fraction of search's traffic.
| Task | Generic dashboard | Chartsy |
|---|---|---|
| Recognising ChatGPT visits | Shows chatgpt.com as a referral source; a custom channel group is needed to separate AI assistants | Recognised automatically from the referrer or utm_source, and grouped as AI |
| Other assistants | Each domain set up by hand in the channel group | Perplexity, Claude, Gemini, Copilot, Grok, DeepSeek and others recognised too |
| Signups | Needs a conversion event you configure | Each signup keeps the source that brought it |
| Paying customers and MRR | Not connected to your subscription billing | Matched to payments in Stripe, Paddle, Freemius, Polar.sh, Creem.io or Lemon Squeezy |
| Whether they stay | Not tracked | Current MRR and churn for customers from each source |
One tag on your website. Visits from ChatGPT and other AI assistants are recognised automatically - no UTM setup needed.
Each signup keeps the source that brought it, so ChatGPT signups stay labelled as ChatGPT.
Connect Stripe, Paddle, Freemius, Polar.sh, Creem.io or Lemon Squeezy and paying customers are matched to the visit that brought them.
SaaS founders who see ChatGPT or other AI assistants in their traffic and want to know whether those visitors pay - before investing time in being recommended by them.
