Haystac Platform / Nashville

Turn messy documents into structured data.

Nashville extracts fields, tables, entities, handwriting, checkboxes, clauses, codes, and relationships from complex documents — so teams can move from manual review to JSON-ready outputs without brittle OCR templates.

Where Nashville fits

Chicago tells Haystac what the document is. Nashville turns it into data.

Nashville is the extraction layer of OmniSuite™. Once Chicago has classified and separated the document stream, Nashville reads the content and pulls out the facts the business needs. That structured data can then feed Orion for grounded reasoning, Polaris for workflow automation, or any host system that needs clean, usable document data.

Nashville is the extraction layer. It sits between document classification and enterprise reasoning — the step that converts whatever Chicago hands over into structured data the rest of the platform (and your systems) can actually use.

The problem

Traditional extraction breaks when documents stop behaving.

Most document extraction systems were built for stable forms and predictable layouts. They read text with OCR, match fields against templates, and rely on rules that work until the format changes. Real enterprise documents do not behave that way.

Labels move. Tables change. Fields appear in different places. Scans are noisy. Handwriting shows up. A single packet may contain forms, notes, attachments, correspondence, and supporting evidence. When the system cannot understand the document, humans become the fallback.

01

OCR reads text, but misses context.

It can capture characters on a page, but it often misses the relationship between a label, a value, a table, a checkbox, and the surrounding business meaning.

02

Templates break when layouts change.

A new vendor form, revised claim packet, different government application, or slightly shifted table can create downstream extraction errors.

03

Manual review becomes the safety net.

People end up correcting fields, checking tables, validating values, and rekeying data into downstream systems.

The Nashville answer

Read the document the way a trained reviewer would.

Nashville treats each document as a visual and semantic object, not a flat text file. It looks at the words, the layout, the surrounding labels, the field positions, the tables, the handwriting, and the structure of the page together. That makes extraction more resilient when formats vary and more useful when the document carries meaning through layout.

Understand structure

Detect fields, labels, tables, regions, checkboxes, signatures, and visual relationships.

Understand meaning

Extract the facts that matter in context — names, dates, amounts, codes, policy numbers, clauses, entities, and line items.

Understand variation

Handle structured, semi-structured, and unstructured documents without rebuilding templates for every new format.

Return usable data

Output structured data that can feed case systems, workflow tools, analytics, RAG pipelines, and downstream automation.

What it enables

Extract the facts your workflows depend on.

Extract fields from complex forms

Capture names, addresses, dates, identifiers, policy numbers, claim numbers, payer details, applicant details, and other business-critical fields.

Pull data from tables and line items

Extract charges, quantities, codes, dates, service lines, financial values, invoice details, and tabular relationships.

Read handwriting and poor scans

Process handwritten, stylized, low-quality, or visually inconsistent content that creates problems for OCR-heavy systems.

Extract entities from long-form documents

Identify clauses, obligations, parties, dates, exceptions, conditions, and relationships in contracts, letters, narratives, and regulatory documents.

Validate and curate results

Review uncertain outputs, correct errors, improve training data, and refine extraction performance over time.

Send clean data downstream

Return JSON-ready structured outputs to host applications, enterprise systems, Orion, Polaris, or partner workflows.

How it works

From document to usable data.

Nashville manages the full extraction lifecycle: understand the page, map the structure, extract the facts, improve the model, and return data your systems can use.

01
Analyze

Understand the page first.

Nashville evaluates the document visually and semantically to understand what it is looking at, how the page is organized, and which content relationships matter.

Not every document needs the same extraction strategy. Nashville supports multiple model types so teams can start fast, handle different document formats, and scale to production without changing platforms.

Production path

Start in minutes. Improve with real documents. Scale without rebuilding.

Many extraction projects stall because the demo model and the production model are not the same path. Nashville is designed so early extraction work becomes the foundation for production-grade automation.

01

Start with a small sample.

Use lightweight models to begin extracting from real documents quickly, without months of labeling.

02

Run documents through the workflow.

Capture fields, values, geometry, confidence scores, and extraction outputs from real business content.

03

Review and correct results.

Use guided curation to validate outputs and turn human review into better training data.

04

Train stronger models.

Use curated results to train higher-fidelity VLMs or MVLMs for production workloads.

05

Scale inside the same platform.

Move from early extraction to production automation without re-platforming or rebuilding the workflow.

“The first model gets you moving. The reviewed outputs make the next model better.”

Capabilities

Built for document understanding, not just text recognition.

Multi-modal extraction

Processes text, visual structure, labels, tables, fields, handwriting, and layout together.

Layout-aware parsing

Understands where information sits on the page and how fields relate to nearby labels and regions.

Table and line-item extraction

Captures structured rows, columns, values, codes, quantities, and financial or clinical details.

Handwriting and scan tolerance

Handles poor-quality scans, handwritten fields, stylized forms, and inconsistent document quality.

No-code curation

Lets teams review, correct, and improve extraction workflows without requiring a full data science team.

Structured API output

Returns JSON-ready data for enterprise systems, partner applications, RAG, reporting, and workflow automation.

Business impact

Less manual entry. Fewer template failures. Cleaner downstream data.

Before Nashville

Manual review is the safety net.

×
Slow document onboarding

Every new format means a new template, a new rule, or a new round of labeling before extraction can start.

×
High review burden

People read, rekey, check, and correct document data because the system can’t be trusted to do it alone.

×
Brittle to change

A vendor revises a form, a scanner shifts a margin — downstream extractions break and rework piles up.

×
Dirty data downstream

Case systems, workflow tools, and analytics get half-structured exports that still need human cleanup.

×
Static model performance

Production use doesn’t make the system any smarter — corrections live in spreadsheets, not models.

×
Demo vs. production gap

The PoC model and the production model are two different rebuilds with different timelines and different teams.

With Nashville

Documents become structured data your systems can use.

Faster document onboarding

Start extracting from new document types without building large template libraries or writing brittle rules.

Lower review burden

Reduce the human effort spent reading, rekeying, checking, and correcting document data.

Resilient to change

Handle layout variation, new document versions, vendor-specific formats, and inconsistent scans with less rework.

Cleaner data for systems

Turn unstructured and semi-structured documents into JSON-ready data downstream applications can use directly.
