## The question this page answers
Why does my brand appear in one AI system but not another
In short
Because each AI platform applies different confidence, safety, and explanation rules.
## Why this matters
Assuming uniform visibility leads to false confidence.
## A practical example
A legal service appears in Google but not ChatGPT due to risk filtering.
## The trade offs
Optimising for one platform may reduce clarity in another.
## Frequently asked questions
### Is inconsistency a problem
Not always, but it must be understood.
### Can platforms converge
Possibly, but not reliably.
