## AI overview

Dropbox describes an in-house cookie auditor that acts like a privacy-conscious user, visits web pages, and checks whether loaded cookies match stated privacy preferences. The approach helps automate quality assurance across more than 200 web surfaces whose pages, integrations, experiments, and cookie behavior can change over time.
