Frequently asked questions
Good to know.
Does this tool send my content to a server?
No. Calculations and transformations are performed locally in your browser; normal website analytics may still record page visits.
Can AI agents call this as an API?
Not as a network API. It is an interactive browser tool and can be used by automated browsers; no backend endpoint is provided.
