Serge

What does Serge actually do?

Serge runs real AI agents — Claude, ChatGPT, Operator, Perplexity, Gemini — on your live e-commerce storefront and shows where they fail to complete a buying task. You type a prompt ("find a black leather backpack and add it to the cart"), Serge dispatches the test, and the report comes back with screenshots, the exact failure step, and a fix snippet.

Which AI agents does Serge support?

Claude (Anthropic computer-use), ChatGPT, ChatGPT Operator, Perplexity, and Gemini today, with new platforms added as they ship browser capability. Each test runs against the actual agent, not a generic headless browser, so the failure modes match what a real customer would hit.

How does an Agent Journey Test work?

You give Serge a buying task in plain English. Serge dispatches a real AI agent against your live storefront and records every step — the URL the agent navigated to, the elements it tried to click, the accessibility tree it parsed, the moment it gave up. The report comes back in about 5 seconds with screenshots and a paste-ready fix for each blocker.

Can I just use Playwright or my QA team for this?

Playwright tests what your selectors do; QA tests what humans do. Neither runs the actual AI agents your customers use. AI agents read the DOM differently — a hard-coded test script with fixed selectors will pass while a real Claude agent quits at a variant selector that has no accessible name. Serge catches the gap.

Is this the same as AI SEO or GEO tools?

No. GEO tools (Athena, Profound, Scrunch) measure whether ChatGPT mentions your brand in its answers. They sit upstream of the customer journey. Serge sits where the customer actually arrives — when an agent lands on your site and tries to find a product and add it to a cart. The two are complementary, not competitive.

How much does Serge cost?

Pro starts at CHF 159/month with daily journey tests, alerts, 12-month retention, and PAYG add-ons for extra runs. Agency is a contact-us tier for teams running tests across multiple client stores. A free tier lets you scan your store and run one sponsored journey test before signing up.

How long does a single journey test take?

About 5 seconds. The agent runs against your live storefront in real time, streams the steps as it goes, and lands the full report with screenshots, the failure point, and a fix snippet. No staging environment to set up, no scenarios to script — paste a prompt, hit Run.

Who is Serge for?

Product Directors and Front End / Engineering Leads at mid-to-large e-commerce companies. The Product Director feels the pain (silent conversion loss to AI shoppers), the FE Lead owns the DOM where the failures happen. Economic buyers are usually the Head of E-commerce or CMO at the same account.
