Can Hotjar capture ChatGPT or Claude sessions on my site?

Generally no. Hotjar is built around human session signals (mouse movement, native scroll, real user-agent strings). When an AI agent visits via a headless browser, the session usually lacks those signals and Hotjar's filters treat it as bot traffic — so it doesn't reach the human-session views. The product works correctly within its scope; the scope is humans.

Should I replace Hotjar with Serge?

No. The tools answer different questions. Hotjar measures what humans do on your store. Serge measures what AI agents fail at on your store. If you already have Hotjar and you're also seeing the gap that AI agents are increasingly part of your traffic, you add Serge — you don't swap.

How is Serge different from Hotjar's heatmap feature?

Heatmaps aggregate human cursor movement and click density. AI agents don't generate cursor movement; they navigate by selectors. A heatmap of an agent session is a meaningless flat field. Serge captures the structural data instead — which DOM elements were targeted, which were missed, which selector logic broke.

Does the Contentsquare-Hotjar combination change anything for AI agent traffic?

Hotjar and Contentsquare are both built around human session capture, so consolidating them under one company didn't add an agent-session layer. The two products together cover the human-experience side of the same conversion funnel.

Compare · Hotjar vs Serge

Hotjar captures humans. Serge captures agents.

Both record sessions on your e-commerce site. Hotjar records what humans do. Serge runs real Claude, ChatGPT, Operator, Perplexity, and Gemini agents and records what they fail at. Different layers of the same shopper experience.

Short version: Hotjar (now part of Contentsquare) has been around for years as a tool for human-session replay + heatmaps. It is built around human session capture — when a session lacks the interaction signals it expects, it generally treats that session as bot traffic. AI agents shopping a storefront via headless browsers fall into that bucket. Serge fills the layer Hotjar doesn't cover.

How they fit

Where Hotjar and Serge fit together

These tools don't replace each other. Hotjar covers human behaviour on your site — drop-off points, click patterns, scroll depth, rage clicks, form-field abandonment. The qualitative layer for human conversion.

Serge is the layer one click upstream of conversion for AI-mediated traffic: can the agent reach the product page, parse the variant selector, hit add-to-cart, complete the checkout? Hotjar can't see those sessions; its filters drop them.

Most e-commerce teams that buy Serge already have Hotjar (or Contentsquare, since the acquisition). The two tools answer different questions about the same store and the same buyer. Run both.
