IBM pitches Bob, an agentic AI development partner for enterprises

IBM is presenting Bob as an AI-powered development partner that works inside a company's codebase. The product page at bob.ibm.com offers a free trial and a download, and frames the tool around three ideas: focused agents, natural-language code generation and command-line automation.

Agents, natural language and the command line

Bob can spawn focused agents and subagents that contribute to a codebase. Each uses its own context, tools and skills, runs in parallel, and can take on long-running tasks in the background while returning only what matters. A feature IBM calls Literate Coding removes the switching between a chat window and the editor: the developer explains what is wanted in natural language and Bob generates the implementation in context. Bob Shell moves the same assistant to the terminal, where it can work interactively, script repetitive tasks and be embedded into CI/CD pipelines.

Analytics and enterprise modernisation

For teams that have to justify the spend, Bobalytics tracks Bob's contributions across the software delivery lifecycle; IBM positions it as a way to drive agentic adoption, prove real business value and optimise costs. The company also sells premium packages with purpose-built modes, skills and workflows for enterprise modernisation, from upgrading Java applications to the latest versions to mainframe and IBM i development. From the IDE, Bob can connect to Red Hat, Instana and other parts of IBM's enterprise stack.

What early customers report

Blue Pearl's chief executive Sai Govender says the company used Bob to move a Java codebase from Java 11 to Java 25 and cut delivery from a typical 30-plus days to three days — an estimated 90% improvement. Steve Cast, practice director at Fresche Solutions, highlights built-in guardrails: Bob operates in modes that let developers approve suggestions before any change reaches source code, and asked about a non-existent RPG op-code it states that it does not understand rather than inventing an answer. Other customers report strong support for RPG and COBOL, an IoT project covering peripheral chips and devices, and an FPS-style prototype built in under 15 minutes. The page collects quotes from named customers including VirtusLab, TechMind, MONO-X, Wolff Bros, Chukyo TV and Novadoc.

IBM is not positioning Bob as another autocomplete tool. Christina Adames, an AI strategist at CDW, describes it as a shift from 'help me code' to 'help me modernize, secure, and scale' — the language IBM uses to pitch the product to large organisations that maintain decades-old systems.
