Parashift/For Software Vendors/Replace Legacy OCR
For Software Vendors · Use Case

Replacing legacy OCR with a zero-shot document AI.

Template-based OCR engines need a maintained template per document variant and break the moment a vendor changes its layout or a form gets a handwritten addition. Parashift replaces the legacy engine completely – as a zero-shot document AI with no training and no templates, integrated as a drop-in replacement behind your existing extraction interface.

500+ European enterprises trust Parashift for sovereign document AI – as a core system or embedded in partner products.

The process today

Every new document variant needs a new template.

Template-based OCR engines only work as long as the layout stays stable. The moment a vendor changes its invoice layout, a form gets a handwritten addition, or a poor-quality scan comes in, your team has to manually rework it or maintain a new template – a recurring maintenance burden that grows with every new customer.

Typical breaking points

What customers maintain templates for today – and won't have to anymore.

These are exactly the points where classic OCR fails – and exactly where Parashift keeps reading without a template.

Migration

From assessment to switching off the legacy engine.

01 · ASSESSMENT

Existing OCR pipeline

We review your current document types, templates, and sources of error.

02 · PARALLEL RUN

Parashift alongside the legacy engine

Parashift processes the same documents in parallel, without touching production.

03 · PHASED CUTOVER

Document type by document type

You switch over one document type at a time, once the results check out.

04 · DECOMMISSION

Legacy OCR & template maintenance go away

One API replaces the legacy engine and manual rework.

Integration

Drop-in behind your existing interface.

Parashift can sit behind your existing extraction API without requiring changes to downstream systems.
