Modernize Agent AIThe AI Recoder for Legacy Code
Legacy systems still run critical business operations, but the knowledge around them is disappearing. Modernize Agent AI helps teams analyze, explain, document, refactor, and recode aging software through AI-guided modernization workflows.

On the road to a billion lines of code, recoded.
The AI Recoder for Legacy Code — measured in real, reviewed output.
Every analyzed and recoded line brings legacy software closer to being understandable, documented, testable, and maintainable.
Verified production usage only. No demo data. No inflated metrics.
A Public Mission Meter for Legacy Code Modernization
Modernize Agent AI tracks verified production usage across analyzed, recoded, and validated lines of code. The mission is simple: help developers and businesses turn legacy software into understandable, documented, testable, maintainable modern systems.
Old Code Still Runs the World
Businesses depend on aging scripts, outdated frameworks, undocumented internal tools, abandoned applications, fragile automations, and systems written by developers who may no longer be available. The code may still run — but nobody fully understands it anymore.
Talent cliff
Legacy languages and frameworks are harder to staff and maintain.
Cloud migration blockers
Monolithic, stateful systems often resist modern cloud deployment.
Security and compliance risk
Old code can contain outdated dependencies, hardcoded credentials, and weak encryption patterns.
Missing documentation
Business logic is often trapped inside unclear code, comments, scripts, and old workflows.
Fragile internal tools
Small changes can break hidden dependencies and undocumented processes.
Expensive modernization
Manual rewrites can take months or years and create major regression risk.
Meet the AI Recoder
Modernize Agent AI is being built to help teams recover, understand, and modernize legacy software. It does not simply generate new code from scratch. It works from existing code, analyzes what it does, explains the logic, identifies risks, and helps produce reviewable modernization outputs.
- Analyze legacy code structure and intent
- Explain old code in plain English
- Generate documentation and modernization reports
- Recommend safe migration paths
- Assist with refactoring and transpilation
- Generate test scaffolds and review notes
- Produce before/after code comparisons
- Keep developers in control of final decisions
$ modernize analyze ./legacy/reporting.vbs
→ Parsed 1,284 LOC across 7 procedures
→ Detected 3 outdated dependencies
→ Found 2 hardcoded credential patterns ⚠
→ Inferred business intent: monthly AR aging report
$ modernize explain --target reporting.vbs
Generates: summary.md, dependency-map.json,

Status: awaiting developer reviewFrom Legacy Code to Reviewable Modernization
Modernize Agent AI is designed for human-guided modernization. It does not blindly overwrite production systems.
- STEP 01
Ingest
Upload code files, snippets, scripts, or connect a repository in a future integration.
- STEP 02
Analyze
The system studies structure, dependencies, variables, control flow, data patterns, and likely business intent.
- STEP 03
Explain
Generate explanations, comments, documentation, dependency notes, and modernization summaries.
- STEP 04
Recode
The AI recoder creates draft modernized code, refactoring plans, transpilation suggestions, and test scaffolds.
- STEP 05
Validate & Review
Developers receive reviewable outputs, risk notes, before/after comparisons, and exportable modernization reports.
Built for the Code Nobody Wants to Touch
From COBOL and classic ASP to fragile PowerShell automations and undocumented Excel macros — Modernize Agent AI is being built for the legacy software modernization work most teams put off for years.
Legacy web applications
Old PHP, classic ASP, outdated JavaScript, old .NET, abandoned web apps.
Business scripts
Shell scripts, batch files, PowerShell, Perl, Python 2, cron jobs, fragile automations.
Office and database tools
VBA, Access applications, Excel macros, SQL scripts, old reporting tools.
Enterprise application code
COBOL, old Java, legacy C#, Visual Basic, monoliths, internal business systems.
Documentation recovery
Convert unclear code into explanations, diagrams, comments, and handoff notes.
Migration planning
Prepare systems for cloud migration, framework upgrades, language transitions, and rebuilds.
Test generation
Create starter tests, regression scenarios, and functional equivalence checks.
Consultant reports
Generate client-ready technical debt summaries and modernization roadmaps.
Practical AI Tools for Real Code Modernization
An AI refactoring tool and code documentation AI designed around the way real engineering teams ship — reviewable outputs, risk awareness, and developer control.
Built for Review, Control, and Security
Legacy code often contains proprietary business logic, credentials, sensitive workflows, and regulated data paths. Modernize Agent AI is being designed around secure processing, human review, and enterprise-friendly deployment patterns.
Human-in-the-loop workflow
Generated outputs are meant to be reviewed before being merged or deployed.
Reviewable modernization reports
Every recommendation should include context, assumptions, and risk notes.
Security-first processing direction
The platform roadmap emphasizes secret detection, safe handling, and customer IP protection.
No blind production changes
The system is designed to assist developers, not silently rewrite production applications.
Enterprise deployment roadmap
Future enterprise options may include private cloud, VPC, SSO, audit logs, and stricter data controls.
Designed for regulated environments
Built for teams that care about compliance, traceability, and control over their codebase.
Security and enterprise deployment features may vary by plan and product stage.
