Swimm will be able to keep up with it. Swimm checks your docs as your code evolves, and notifies you if your changes affect your documentation. Access docs right next to the code they refer to. Stay in your IDE and your flow. When you click on a link, your IDE will open a new tab with the documentation perfectly rendered from Markdown.

IBM Bob is an AI SDLC partner and an agentic integrated development environment designed to transform how developers work with real codebases. It is not just another autocomplete tool; it helps teams move from “help me code” to “help me modernize, secure, and scale.” Bob augments existing workflows across the software development lifecycle, helping users write, test, upgrade, refactor, debug, document, and secure software with confidence. Developers can turn natural language into working code, use single-line and multi-line code completion, clean up and fix existing code automatically, ask questions about a codebase, automate repetitive workflows, and scaffold new files or entire projects. Bob includes specialized modes that tailor its behavior for different tasks, including Code mode for writing and modifying code, Ask mode for explanations, Plan mode for designing before implementation, Advanced mode for complex tasks, and Orchestrator mode for coordinating multi-step projects.

AWS Transform is an agentic AI service from Amazon Web Services that automates and accelerates the modernization of legacy workloads, specifically .NET, mainframe, and VMware environments. Built on AWS’s migration and modernization experience, it deploys specialized AI agents to carry out tasks like assessment, code analysis, dependency mapping, refactoring, decomposition, validation, and planning, many of which run in parallel, to speed up large-scale transformations. Through a shared workspace and natural-language chat interface, cross-functional teams can collaborate, track progress, and manage modernization projects from end to end. AWS claims AWS Transform can make .NET apps port up to 4 times faster, greatly speed VMware configuration conversion, and compress mainframe migration timelines (years down to months), while also helping reduce legacy licensing, infrastructure cost, and ongoing maintenance expenses.

Rocket Assembler Code Refactoring is a specialized modernization solution that automatically restructures legacy Assembler code into structured pseudocode or modern languages such as COBOL, C, or Java without altering external behavior, enabling faster, lower-risk modernization and improved maintainability. Assembler code is notoriously dense, poorly documented, and supported by a shrinking pool of specialists, making maintenance slow, costly, and error-prone; this product addresses those challenges by delivering semantics-preserving, auditable transformations that reduce outages and secure modernization without sacrificing stability. Its fully automated core engine uses mathematically guaranteed logic equivalence to eliminate conversion risk, dramatically accelerating projects while ensuring that refactored outputs are semantically identical to the original code.

For years, enterprises have been promised useful tools for application modernization, digital product development, and no-code/ low-code. But these promises have not been kept. Instead, enterprises got a thousand disjointed point solutions, that don't scale, and ended up captive to proprietary languages and fixed vendor solutions. Enterprise customers face an urgent need to modernize, with ~80% of IT budgets locked up in maintaining old legacy systems. They demand fast integrations with simplified, lower-cost implementations. There is tremendous competition. Securing market share is hard enough. Growing is significantly harder. Enterprises need to build complex omnichannel digital products that provide an excellent user experience. People are sick and tired to be locked into proprietary programming languages, with compounding vendor fees and add-ons. Large enterprises need the freedom to build and extend easily their digital platforms.
