Key statistics
10%
Scent Studio's bottle price moved from $120 to $108 across weekly checks, a 10% weekly price change.

Supporting context
Kamil Banc draws on his experience running an online fragrance store to demonstrate a workflow where Codex builds a private competitor monitor without template editing. The system saves public observations weekly and compares them over time, so users see actual price movements rather than relying on memory. Using the fictional Northline Parfum example, he distinguishes a genuine 10% weekly price change from the 32.5% customer-facing discount shown on the product page. The methodology emphasizes that the monitor supplies evidence while the human weighs costs, product fit, customers, and goals before responding. This positions AI as an observation and comparison tool rather than an autonomous decision-maker.
