What does Felix AI actually detect?

Felix flags sessions that look agent-driven based on behavioural signals — lack of mouse movement, navigation timing patterns, viewport size, header anomalies. It tells you a session is probably agent-driven, but it doesn't test whether that agent can complete a buying task on your site. Detection is upstream of remediation.

Should I buy Serge instead of Quantum Metric with Felix?

Not as a replacement. Quantum Metric is an enterprise analytics platform; Serge is a focused journey-test product. The question is whether you also need to test whether AI agents can complete buying tasks on your site, beyond detecting that some sessions are agent-driven. If yes, you add Serge.

Does Felix AI test whether agents can complete tasks on my site?

Not as a published feature. Felix is a detection layer over recorded customer sessions — it flags traffic that looks agent-driven. It does not generate synthetic agent traffic against your storefront to test buying-task completion. Serge does.

Does Quantum Metric run AI agents against my site?

Not as a published feature. Felix detects AI-likely traffic in existing customer sessions; the product does not generate agent traffic against your storefront to test task completion. Serge runs real Claude, ChatGPT, Operator, Perplexity, and Gemini agents against your store on a defined buying task.

Compare · Quantum Metric vs Serge

Felix AI detects agents. Serge tests them.

Quantum Metric is the enterprise digital analytics platform; "Felix AI" is its AI-traffic detection feature. Serge runs real AI agents against your store and captures whether they can complete a buying task. Two different "AI" categories on the same conversion funnel.

Short version: Felix AI flags traffic that looks agent-driven based on behavioural signals. Useful for visibility, but it stops at detection. Serge runs the agent itself against your storefront with a buying task and captures the failure point as structured data with a fix snippet per failure. Different product shapes for different questions.

How they fit

Where Quantum Metric and Serge fit together

Felix AI inside Quantum Metric is a real product that flags AI-mediated traffic in customer analytics. It addresses a visibility gap: agent traffic often lands in "direct" or gets filtered entirely by older analytics surfaces. Surfacing it as its own bucket is useful.

What Felix doesn't do is run agents against your store with a buying task and capture the failure point. That's a different product shape. Serge is built ground-up around that motion — real Claude or ChatGPT shopping your storefront, structured failure capture, paste-ready fix per failure.

Some enterprise teams need both. Felix tells you how much of your traffic looks agent-driven. Serge tells you whether those agents could actually complete a buying task on your site, and if not, what to fix.
