Enterprise COBOL Code Analysis and Documentation Platform
Automate COBOL documentation and map dependencies across CICS, JCL, and DB2—backed by expert review. This is not "just AI": COBOLpro is a deterministic static code analyzer with COBOL‑specific parsers and rules, producing repeatable, audit‑ready outputs. Deploy in your VPC or on‑prem without disrupting production.
Trusted by leading enterprises
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.
Slow, Risky Change
Without accurate documentation and impact analysis, even minor updates require manual tracing and guesswork.
Audit & Outage Exposure
Opaque data flows and missing lineage create audit friction and increase the chance of incidents during peak periods.
The cost of inaction
Without proper knowledge retention and documentation, organizations face system outages, compliance risks, and potentially catastrophic business disruption.
Deterministic analysis + expert review → audit‑ready artifacts
COBOLpro automates COBOL documentation and lineage, ties SME knowledge to code, and produces evidence your teams and auditors can trust—without disrupting batch windows.
Deterministic Static Analysis
Generates repeatable artifacts: call graphs, copybook/I-O maps, data lineage, and JCL schedule docs
Expert Review Built‑In
SME validation ensures accuracy for audits and change decisions; no black‑box hallucinations
COBOL Managed (Staffing)
Optional managed squads and staffing to operate and sustain your COBOL estate with enterprise SLAs

How COBOLpro Works
Our three-step process systematically transforms your legacy COBOL systems into well-documented, maintainable assets that your team can confidently manage.
Analyze & Document
Our AI-powered engine analyzes your COBOL codebase using proprietary parsers and fine-tuned language models to generate comprehensive, deterministic documentation.
Capture Knowledge
CLIP systematically captures expert knowledge through structured interviews, workflow documentation, and testing practices to build your organization's knowledge graph.
Maintain & Develop
Our AI-powered IDE provides COBOL-specialized development tools with digital replicas of senior expertise to guide newer developers in system maintenance.

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.
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.
Why COBOLpro vs. Other Products
Evidence‑first comparison for regulated COBOL estates.
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."
