Feature-by-feature comparisons. US$3 per tracked question per region per month, all eight AI platforms available on every account, API included. New accounts get $6 in one-time invoice credit. Tracking needs a card on file; the website audit is free. Here's how that compares.

Each page states what SignalKit does. The other column is transcribed by hand from that company's own public pages on the date shown there, and nothing rechecks it — so treat it as a starting point and read their pricing page before deciding.
