Which AI Sent vs Attrifast: which one fits your business?

Summary

Choose Attrifast if you sell online and get paid through Stripe or Shopify. It joins recognised AI visits to real payments and costs less to start. Choose Which AI Sent if your customers fill in a form, book or phone: service businesses, clinics, trades and the agencies that work for them. It follows each AI visitor to a named lead and asks every customer how they found you, which catches the people who never clicked.

Where Attrifast is the better tool

• You are paid through Stripe or Shopify. Attrifast matches AI visits to the actual payment, with no manual step. We don’t connect to Stripe.
• You want deeper prompt tracking. Its visibility module tracks more prompts and competitors than our weekly check.
• You want the lowest paid price. Its Starter plan is $9.99 a month.

Where Which AI Sent is the better tool

• Your customers call, book or ask for a quote. There is no payment to match, so the useful record is the lead. We keep each lead with its source and the pages it read (see AI lead attribution).
• Many of your customers never click. People ask ChatGPT, then search your name or phone. Only asking them recovers those customers (why every tool undercounts).
• You report to clients. The Agency plan gives every client a private, view-only dashboard.
• You want to start free. The free plan has no time limit.
