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Businesses depend on aging scripts, outdated frameworks, undocumented internal tools, abandoned applications, fragile automations, and systems written by developers who may no longer be available.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Old code can contain outdated dependencies, hardcoded credentials, and weak encryption patterns.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→ Detected 3 outdated dependencies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,
risk-notes.md, modernization-plan.md
$ modernize recode --to typescript --plan plan.md
Drafts: reporting.ts, reporting.test.ts

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.
Start with a Legacy Code Risk Scan
The first step in modernization is not a rewrite. It is understanding what you have. The Legacy Code Risk Scanner gives developers and teams a read-only first look at old code before they plan documentation, refactoring, transpilation, or recoding work. Modernize Agent AI — The AI Recoder for Legacy Code.
Read-only by design. No code execution. No raw source stored for preview scans. Preview scans do not increment the Recoded Counter.
Pricing Research
Pricing will be finalized after the platform is working, tested, and validated through customer discovery. Modernize Agent AI needs a working platform before pricing can be finalized. The current ranges are planning hypotheses only. Final pricing will be shaped by founder testing, approved tester feedback, paid pilot data, usage metrics, comparable market analysis, codebase size, modernization complexity, and enterprise security requirements.
No billing is active. No checkout is available. Pricing may change before public launch. All ranges below are labeled tentative planning ranges only.
Priced around modernization value
Modernize Agent AI is priced around legacy modernization value, not simple autocomplete. The platform is being designed for code analysis, documentation recovery, risk scanning, refactoring, transpilation assistance, validation direction, and reviewable modernization reports.
- Lines of code analyzed
- Lines of code recoded
- Project-level modernization reports
- Team workflows
- Security-conscious handling

Pricing philosophy
Priced for Modernization Value, Not Autocomplete
Modernize Agent AI is being designed for legacy code risk, documentation recovery, modernization planning, and reviewable recoding workflows. Tentative pricing reflects the size, sensitivity, and business value of legacy modernization work rather than simple code completion.
- Small users need affordable discovery tools.
- Professionals need reportable workflows.
- Teams need collaboration and project history.
- Enterprises need governance, security, and deployment options.
- Regulated organizations may need private infrastructure.
Tell us which tentative plan fits your legacy code problem.
This helps shape early access, tester selection, and future pricing. Submitting pricing interest does not create an account, start a subscription, grant tester access, or activate product features.
No billing is active. Your submission is stored securely and is only visible to Modernize Agent AI owners and admins.
