IBM Bob
IBM Bob is an AI-assisted development tool designed to support developers across the software development lifecycle. It helps interpret developer intent and provides assistance when working with real-world codebases by using contextual awareness of the surrounding project. Bob operates across different environments and can support a range of development activities, including understanding existing code, generating suggested changes, and helping with end-to-end tasks.
Codex
Codex is OpenAI’s agentic coding partner built to accelerate real engineering work end-to-end, helping you plan, implement features, refactor, review, and ship releases while fitting into the tools and workflows developers already use. Rather than acting like a chat-only assistant, it’s positioned as a “build with agents” experience that can take on substantive tasks (and context) across a codebase so you spend less time on repetitive execution and more time on decisions, design, and quality.
