Collected facts
CompetitorLens monitors your competitors daily and turns what changed into a short, evidence-backed brief. It detects price changes, new launches, stock changes, promotions, and website copy changes, and links every claim to its public source. It matches your products to a competitor's so you can compare the same item, and only claims a price difference when the match is confident. When data is thin or prices aren't comparable across currencies, it says so instead of guessing.
Structured evaluations
