Oneengine. Every compliance workflow.

Curvestone reads real documents, applies your compliance rules, and writes an auditable verdict.

Three ways to deploy.

API

Curvestone runs inside your CRM, LOS, or case management system. Cases trigger automatically, and results return as structured data, ready for your downstream workflows.

Reviewer interface

A purpose-built UI for compliance and QA reviewers. See the verdict, the evidence behind it, and override with a reason — every action logged.

Web portal

Drag and drop a case file, run the check, see the result. No integration required — ideal for evaluating Curvestone or running ad-hoc compliance checks.

One platform. Built in layers.

Curvestone is the platform for compliance — engine, intelligence, evidence, and data, all in one stack. Accuracy, security, and audit posture are guaranteed at the platform layer, not re-proven product by product.

Layer 01 The pipeline

Compliance automation engine

Execute your compliance rules into deterministic, repeatable workflows. Same case, same rules, same result — every time.

Layer 02 The intelligence layer

Document intelligence

Vision, Intelligent OCR, and LLM understanding of the documents your clients actually send.

Policy reasoning

Interprets your rules in context. Not keyword matching. Reasons across the whole case, not field by field.

Evidence & audit layer

Every finding traced back to the source paragraph. Immutable log of every check, override, and timestamp.

Layer 03 The data layer

Source connectors

APIs to CRM, case management, open banking, credit reference agencies (Experian, Equifax, TransUnion), document sources.

Structured outputs

JSON via API, PDF reports, dashboards, and regulator-ready audit exports — feed straight back into your existing systems.

How it works

Policy in. Audit out.

The same case, run again, against the same rules, gives the same result. Consistent, auditable, version-controlled — every step logged.

Step 01 AI trigger

A case reaches a defined stage in your LOS or CRM. Each document automatically classified by type — vision, OCR, language understanding.

Step 02 Ingest & classify

Full document pack injected. Each document classified by type. Each field extracted. Cross-checked across documents and against system data for consistency.

Step 03 Extract & cross-check

Key data points extracted. Cross-checked across documents and against system data.

Step 04 Apply your rules

Credit policy, eligibility, suitability, regulatory conduct, Consumer Duty checked against your encoded rules.

Step 05 Graded outcome

Pass, amber, or fail — with specific issues flagged, evidence references, and remedial actions.

Step 06 API return + audit

Results return via API into your LOS, QA tools, or dashboard. Every decision logged for audit.

Proof

“99%+ accuracy. Benchmarked against your team. Case reviews in 1-3 minutes. 100% coverage, not sampling.”

Multi-modal processing

Real documents. Not the clean ones.

Handles the documents your clients actually send — payslips, bank statements, tax returns, IDs, emails, and password-protected PDFs. Read in context, traced back to source.
