The anatomy of a probe

Watch the price disassemble. Each axis of your digital identity peels away to reveal what was actually driving the markup.

Submit your target

Drop any product, flight, or booking URL into the scanner. If it carries a price tag, JACOBI can find its real range.

02

The swarm launches

24 identities disperse across four discrimination axes — location, device, cookies, referrer — striking the URL in coordinated waves.

03

Patterns emerge

Every response is cross-referenced. Statistical outliers become evidence. Pricing bias becomes readable data.

04

A plain-English breakdown of what you'd save with a different profile — and exactly which vector was used to overcharge you.

Why it matters

Pricing discrimination
is the norm.

Companies build algorithms to read your willingness to pay from your browser. JACOBI makes those algorithms visible.

“Two people, same booking, same seats — separated by $60 and a browser setting.”
