Critical Business Risk

The risks of opaque COBOL systems compound over time

Critical COBOL systems run the business, yet teams lack deterministic documentation, data lineage, and change impact. Without these artifacts, organizations face slower delivery, audit friction, and higher outage risk.

Knowledge Leaving the Building

Critical business logic lives in people and code comments. As SMEs retire, teams lose the context needed to make safe changes.

65% of COBOL experts retire by 2029
Observed risk area

Slow, Risky Change

Without accurate documentation and impact analysis, even minor updates require manual tracing and guesswork.

300% longer debugging without docs
Observed risk area

Audit & Outage Exposure

Opaque data flows and missing lineage create audit friction and increase the chance of incidents during peak periods.

Evidence gaps and fragile batch windows
Observed risk area
WARNING

The cost of inaction

Without proper knowledge retention and documentation, organizations face system outages, compliance risks, and potentially catastrophic business disruption.

System outages during critical periods
Regulatory compliance failures
Complete loss of business functionality

How COBOLpro Works

Our three-step process systematically transforms your legacy COBOL systems into well-documented, maintainable assets that your team can confidently manage.

STEP 01

Analyze & Document

Our AI-powered engine analyzes your COBOL codebase using proprietary parsers and fine-tuned language models to generate comprehensive, deterministic documentation.

✓ No disruption to existing systems ✓ Enterprise-grade security ✓ Immediate documentation output

Three Pillars. One Outcome: Safe Modernization.

A unified flow: Static Analysis produces evidence → CLIP captures SME knowledge → IDE operationalizes fixes. Start simple, reveal more detail as you go.

Code Documentation Engine

AI-Powered Analysis & Documentation

Uses COBOLpro proprietary parsers combined with fine-tuned language models to generate deterministic, domain-specific documentation through deep static analysis of COBOL codebases.

Key Capabilities:

  • Proprietary COBOL parsers
  • Fine-tuned LLM models
  • Deterministic documentation
  • Deep static analysis
  • Business logic extraction

CLIP Knowledge Platform

Capture & Learning Intelligence

Structured offboarding system for COBOL and RPG experts that captures workflows, testing practices, and business logic to build organization-specific knowledge graphs beyond traditional interviews.

Key Capabilities:

  • Structured expert interviews
  • Workflow documentation
  • Testing practice capture
  • Business context mapping
  • Knowledge graph creation

AI-Powered IDE & Fixing

Digital Expert Guidance

Fine-tuned COBOL models with RAG create digital replicas of senior expertise in a modern IDE (Cursor-like) specialized for COBOL that guides and pairs with newer developers.

Key Capabilities:

  • COBOL-specialized IDE
  • Fine-tuned AI models
  • Digital expert replicas
  • RAG-powered assistance
  • Junior developer guidance

Unified Platform, Comprehensive Solution

Unlike fragmented point solutions, COBOLpro provides an integrated approach that addresses documentation, knowledge retention, and ongoing maintenance in one cohesive platform.

• Single source of truth• Integrated workflows• Consistent data models• Unified user experience

Deterministic Analysis + AI Assistance

COBOLpro is a deterministic static code analyzer with COBOL‑specific parsers and rules. AI is used as an assistant— grounded on artifacts—not as a black box. Outputs are repeatable, reviewable, and audit‑ready.

Static Analysis & COBOL Parsers

Lexers/parsers per dialect, control/data‑flow graphs, copybook resolution, and I/O mapping produce deterministic artifacts.

Rules Engine & Domain Heuristics

COBOL idioms, JCL patterns, CICS/DB2 access, and error‑handling conventions are encoded as rules for consistent findings.

Repeatable, Audit‑Ready Outputs

Call graphs, I/O maps, field‑level lineage, and JCL schedules are versioned and exportable (PDF/HTML/JSON/Git).

Where AI Helps (and Where It Doesn’t)

  • Grounded summaries: AI explains code paths and artifacts using Retrieval‑Augmented Generation (RAG) strictly from outputs.
  • IDE assistance: estate‑aware hints for navigation, guardrails, and best practices.
  • No model training on your code: customer code is never used to train models; analysis is read‑only.
  • Determinism first: authoritative sources are static analysis artifacts and rules; AI never overrides them.
Result: evidence you can trust for audits and operations—faster onboarding and safer change.

Trusted by Enterprise Leaders

From critical banking systems to healthcare processing, and manufacturing operations. Organizations worldwide trust COBOLPro for their legacy system continuity needs.

"We had a 65-year-old developer retiring next month with 30 years of knowledge about our core payment system. COBOLPro helped us document what he knew before he left. Now we're not panicking every time something breaks."

IT Director

European Regional Bank

"Honestly, we were skeptical at first. But they actually understood our old mainframe code better than our current team. Saved us from a costly rewrite that would have taken 2 years."

CTO

North American Insurance Company

"Our reservation and ticketing systems handle millions in daily transactions. We needed someone who wouldn't break things while helping us understand what we actually have running. They delivered exactly that."

VP of IT Operations

Central European Airline

"The audit trail documentation they provided helped us pass our compliance review. Finally, someone who gets that these systems actually work and just need proper documentation."

Systems Manager

Canadian Insurance Group

"Look, I've been in IT for 25 years. These COBOL systems aren't going anywhere - they process our core business. COBOLPro helped us stop treating them like a problem and start managing them like the critical assets they are."
