Map of your system
Get a complete overview of your codebase’s
architecture, including programs, modules, screens,
jobs, and their relationships. Document business logic
of programs while ignoring boilerplate code.
Understand dependencies

Reverse engineer your business rules giving non-
technical stakeholders immediate access to the current
specifications.
Clarity for modernization teams
Built for trust
Too many AI based solutions fail to deliver in production because LLMs are not reliable on complex legacy codebases. Swimm is built differently. Our foundation of advanced deterministic code analysis combined with the power of AI delivers results you can trust.
Enterprise-grade.
Secure by design.
