Tracker
What changes at ChatGPT, dated.
A fixed set of 26 German questions runs against ChatGPT every morning — always the same wording, otherwise the comparison would be worthless. The tracker compares network and response object field by field with the day before. A change only counts once it holds for two measuring days.

Ads
Does ChatGPT show ads? To whom, when, where.
A free account asks 20 ad-adjacent prompts every day. The tracker reads along on the bazaar endpoint and records every ad — advertiser, format, position, first seen on.
Knowledge base
Every interface, every field — explained.
When the tracker reports a change, next to it stands what the object is: structure from the measurement data, effect on visibility, change history, dated external sources.
