Every form submission, in the person's own words, with where they came from. Label each one so tests are judged on good leads, not just more leads.
“Can you deliver a adjustable base to Panorama Hills this week?”
“Do you have the hybrid mattress in a king in stock? Want to try it in store Saturday.”
The AI labels every lead. “Needs review” means it was unsure, so a person decides; anyone can change any label. The AI reads the answers only, never names, emails or phone numbers.
