Engine

Field contributors send prices by WhatsApp photo or voice note; code extracts and dedupes; the brain scores each submission's plausibility; outliers go to a person.

Rulebook

What correct means here, and the mistakes we've already caught. It grows one job at a time.

  1. R01Every price has a market, a date and a contributor.
  2. R02Outliers beyond two standard deviations are held for review.
  3. R03Contributors are paid per verified submission.
