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.
“Need a 5x10 unit starting the 1st. Moving out of my apartment in Airdrie.”
“Do you have a 10x20 drive-up available this weekend? Ready to reserve.”
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.
