Frequently asked questions

Does it execute page JavaScript?
No. It parses the supplied markup as HTML without executing scripts.
Why might rendered metadata differ?
Client JavaScript can alter the DOM after the original source loads; supply rendered HTML when that matters.
Is my data uploaded?
No. Analysis and generation happen entirely in your browser.
