Understand code faster, document smarter with AI

Bring AI-powered documentation and code understanding capabilities to your workflow. Navigate complex codebases efficiently, whether building modern applications or modernizing critical mainframe systems.

Swimm offers two powerful solutions:

Continuous Documentation: Use AI and code-coupled docs to create, discover, and automatically maintain documentation for evolving codebases.
Mainframe Documentation Generation: Specialized tools to analyze, understand, and document complex legacy mainframe systems.

Continuous documentation

Keep documentation accurate and accessible without the usual toil.

Create with AI

Write docs linked directly to code elements. Use AI assistance (PR2Doc, Snippets2Doc) to generate documentation drafts quickly.

Discover in the IDE

Access relevant documentation alongside your code within Visual Studio, minimizing context switching. Find docs easily with AI chat and proactive Doc Rules.

Maintain Automatically

Swimm's patented Auto-sync keeps docs up-to-date as code changes. Integrate checks into your CI pipeline (GitHub, Azure DevOps, etc.) to ensure documentation remains trustworthy. Documentation lives as .swm files in your Git repo.

Mainframe documentation generation

Tackle the challenge of poorly documented mainframe systems. Swimm helps you analyze and understand applications while backfill documentation.

Automated Analysis

Understand what your mainframe code does by analyzing structures, dependencies, and data flows. Extract and visualize business rules.

Backfilling

Generate overview documentation for critical system components. Capture expert knowledge before it's lost.

Secure & Scalable

Mainframe code analysis runs securely within your network ("Local mode") and scales to millions of lines of code.
