The brief

Teams were keying data from a high volume of mixed-quality documents — scans, photos, and forms in several layouts. The work was slow, error-prone and impossible to scale during peak periods, and compliance demanded a verifiable trail for every field.

The client needed a pipeline that could read almost anything, extract the fields that mattered, validate them against business rules, and escalate only the cases a person genuinely needed to see.

What the client asked for
  • Stop keying data by hand from high volumes of mixed-quality documents.
  • Read scans, photos and forms across several layouts — including handwriting.
  • Validate every extracted field against business and compliance rules automatically.
  • Escalate only genuinely uncertain documents to a human reviewer.
  • Maintain a verifiable, field-level audit trail for compliance.
  • Absorb peak-period volume without temporary staffing.

Our AI-native approach

We built an IDP/ICR pipeline that treats each document as a sequence of decisions — classify, extract, validate, route — each with a confidence score. High-confidence documents pass straight through; anything uncertain is sent to a focused human-in-the-loop review with the model's best guess pre-filled.

Following our AI-driven agenda, we mined the existing document corpus up front to understand the real distribution of layouts and edge cases before a line of extraction logic was written.

What we built

Multi-format ingestion

Scans, photos and digital files are normalised, de-skewed and quality-checked on entry.

Classification

Each document is routed to the right extraction model by type and layout.

OCR & ICR extraction

Printed and handwritten content is read, with field-level confidence on every value.

Rule-based validation

Extracted fields are checked against business and compliance rules automatically.

Human-in-the-loop review

Only low-confidence cases reach a reviewer, pre-filled with the model's proposal.

Audit trail

Every field carries its source, confidence and reviewer action for full traceability.

04

How we built it

Discovery began with the document corpus itself: we mined the real distribution of layouts, languages and edge cases so the pipeline was designed for reality rather than an idealised sample. We made confidence a first-class concept early on, because it is precisely what lets the system route work safely between automation and human review.

We delivered by document type in phases, each gated on accuracy against a human-labelled set before going live. Reviewer corrections were wired back into training from day one so accuracy compounded rather than plateaued, and a senior pod owned the ML while integrating cleanly with the client's existing systems.

How it works

1

Ingest

Documents are normalised and quality-scored.

2

Classify

The type and layout are identified.

3

Extract

OCR/NLP pulls structured fields with confidence.

4

Validate

Rules and cross-checks confirm or flag each value.

5

Route

Clean documents pass through; uncertain ones go to review.

The intelligence layer

The extraction stack pairs OCR with NLP classification and named-entity models tuned to the client's document set. Confidence is first-class: it decides routing, so the system gets faster as the models learn, and reviewers spend their time only on genuine ambiguity.

Validated corrections feed back into training, so accuracy compounds rather than plateaus.
