Who it is for

Sellers, agencies, and agents deciding which search terms to test next without buying a rank-tracking subscription.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday compares only the listing copy you paste in. It fetches no competitor page, treats supplied competitor copy as untrusted data, never follows instructions inside it, and returns extracted terms rather than competitor sentences to copy. It does not publish listings or edit your copy for you.
