AI for COBOL, Running on Your Own Hardware
AI for COBOL, built by COBOL experts. Your core systems hold decades of business knowledge. Much of it is undocumented, and the people who know it best are retiring. We use AI to help you understand, document and modernize your legacy code, without your source code ever leaving your premises.
Why it matters
Business knowledge, locked in code
Core COBOL systems run some of the most important work in your organization, shaped by years of changes. The reasons behind many of those changes are no longer written down anywhere.
When experienced developers retire, that knowledge leaves with them. New developers face a large, unfamiliar codebase, and every change carries the risk of breaking something no one expected. AI can help your team see how the system fits together, as long as your source code stays under your control.

What we offer
What our AI for COBOL delivers
- AI-assisted code analysis and documentation
- Inventory, dependency maps and documentation of your estate
- Mapping of programs, data and job flows
- COBOL AI assistants your developers can ask about your code
- Capturing your experts' knowledge before it's lost

Benefits
What you get
Faster onboarding
New developers get up to speed sooner.
Less risk
Change code with a clearer view of what it affects.
Knowledge that stays
What your experts know stays with your organization.
AI, inside the perimeter
COBOL experts and AI engineers on the same team. CV Systems has built mission-critical systems for financial institutions since 1977, its own products are written in COBOL, and the AI that helps you understand yours runs on your own hardware.

FAQ
AI for COBOL: FAQ
Does our source code leave our building?
No. The AI runs on your own hardware, on your premises. Your code is never sent to outside AI services.
Does it replace our COBOL developers?
No. It helps your developers understand the code faster and change it with more confidence. Your team stays in charge of every change.
Which systems does it cover?
Mainframe COBOL, CICS and JCL, and other legacy financial systems.
Can AI help with COBOL modernization?
Yes. AI maps programs, data and job flows so your team can plan changes with a clear view of what they affect. Our mainframe modernization services then move one workload at a time, proven before cutover.
Is mainframe AI safe for a bank?
It runs on your own hardware, on your premises, and your code is never sent to outside AI services. Your experts review the results, and your team stays in charge of every change.
Can your engineers also make the changes?
Yes. Our U.S.-based mainframe and COBOL engineers handle development, maintenance, analysis and testing, on-site, remote or as fixed-scope contract projects.
Local AI only
Everything runs on hardware you own, on your premises. Nothing is sent to outside AI services.
Plan your local AI.
We design and build the hardware, or deploy on the hardware you already own. Your data stays in your building.
