A practical workflow

  1. Upload a document image or PDF page, optionally crop to a single record, add known context, then process with AI to get transcription, translation, and extracted data for review and confirmation.
  2. Confirming a record saves it and its people; matching runs in background and flags possible duplicates for user review.
  3. Use the Research Companion to ask about matches and approve merges automatically if desired.
