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.
