Electoral Roll Digitization

AI-powered extraction of voter data from Indian electoral roll PDFs — Kolkata District, West Bengal
Why this exists: In 2025–26, the Election Commission of India launched a Special Intensive Revision (SIR) of electoral rolls in West Bengal and Bihar — an exercise the ECI itself called unprecedented. In West Bengal alone, the final roll left 60 lakh voters marked "Under Adjudication", their right to vote uncertain. Yet the Commission publishes this data only as scanned PDF images — no searchable database, no structured data, no public dashboard. This project uses AI vision models to extract every voter record from these PDFs, making SIR's impact measurable and open to public scrutiny for the first time.
