The Platform
One AI platform. Three products. Zero downtime.
Demistifier maps your legacy estate, Transformer converts it, and Code Flux keeps it healthy after cutover — all driven by AI that understands COBOL at a semantic level.
Knowledge graph explorer — map every call chain, copybook, JCL job and CICS screen before you change a line.
Jump to product ↓COBOL → modern language, cloud-ready. Complexity scoring, reviewable AI plans, and generated unit tests.
Jump to product ↓Change workflow — edit → impact → approval. Sandbox branches with blast-radius preview from the graph.
Jump to product ↓How It Works
01
Map
Demistifier scans your repositories and builds a full knowledge graph of every program, copybook, JCL job, data file and CICS screen.
02
Plan
Transformer scores each program by complexity and generates a reviewable, step-by-step conversion plan before any code is touched.
03
Transform
AI converts COBOL to your target language, generates unit tests, and the code reconciler validates logic coverage line by line.
04
Validate
Code Flux opens a sandbox branch for every change, previews blast-radius from the graph, and routes approvals before merge.
Demistifier
See how every COBOL program connects
Point Demistifier at a repository and it maps the call chains, copybooks, JCL jobs, data files and CICS screens into one navigable knowledge graph — so you can debug across the whole system, not one program at a time.
- Full-system call graph — CALL, PERFORM and dynamic links
- Copybooks, JCL & data access fully mapped
- Impact & path analysis before you change a line
- Risk & dead-code heatmap
Demistifier · Graph view
Every dependency, one navigable graph
Drill into any program to see its calls, data access, and vendor black-boxes. Dashed edges flag code with no source — the risks that surprise migrations are visible on day one.
- CALL / PERFORM edges with direction
- Data and DB access mapped per program
- Vendor black-boxes detected and isolated
Transformer
COBOL → Java, with a reviewable plan
Transformer scores every program by complexity — lines of code, call depth, embedded SQL, vendor black-boxes — then generates a step-by-step conversion plan you review before any code is written.
- Complexity scoring: LOC, calls, embedded SQL, black-boxes
- Reviewable step-by-step transformation plans
- Code reconciler validates logic coverage after conversion
Code Flux
Safe change management, before and after cutover
Code Flux wraps every change in a sandbox branch, previews the blast radius from the knowledge graph, and routes approvals before merge — so post-cutover maintenance is as safe as pre-cutover migration.
- Sandbox branches for every change
- Blast-radius preview from the knowledge graph
- Approval routing before merge
Security built into every step
Your source code never leaves your network. Yumesorai deploys on-prem or inside your VPC, with a full audit trail for every AI decision.
On-prem & VPC deployment
Your source code never leaves your network. Yumesorai runs inside your data centre or VPC — nothing is sent to external servers.
Compliance preserved
Regulatory mappings (HIPAA, PCI-DSS, SOX) are tracked through every transformation step so auditors see a clear chain of custody.
Full audit trail
Every AI decision, plan approval, and code change is logged with user, timestamp, and rationale — exportable for any audit framework.
Works with your stack
Yumesorai plugs into the languages, databases, CI/CD pipelines and source-control systems you already use.
