Field notes
PageLens uses a browser extension and cloud runs rather than locally maintained selectors, according to the homepage. A user describes the desired signal, selects hourly or daily checking, and receives a recorded result with changed values and context. Demonstrated examples include a product price crossing a threshold, market indexes moving more than 1%, Bitcoin exceeding a 4% daily move, and selected social posts filtered to original updates.
