Lesson · OCR Engine

OCR without review is liability.

All lessons

Problem

Dense bilingual bulletins must become structured matter fields without retyping — and without silent errors.

What happened

Text extraction alone still left structure wrong. Auto-merge fantasies create false confidence: the system looks done when the field is wrong.

Why it happened

Demos reward “upload → text.” Legal desks reward provenance and confirmation.

What changed

Staged pipeline with confidence and a mandatory human review gate before register merge.

What I’d do differently

Design the review UI before choosing an OCR vendor. Never ship a path that writes the system of record silently.
