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.
“Moving into a house in Tuscany next month and the inspection flagged window replacement.”
“window replacement for a rental I own in Royal Oak. Tenant is in, need someone reliable.”
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.
