Jules is Google's autonomous AI coding agent powered by Gemini 2.5 Pro, designed to handle complex development tasks asynchronously while developers focus on high-priority work. Jules clones your codebase into a secure Google Cloud virtual machine, understands the full project context, and executes tasks such as writing tests, fixing bugs, building new features, bumping dependency versions, and generating audio changelogs. It integrates natively with GitHub, so there is no context switching or extra setup required. Jules plans its approach before executing, shows you its reasoning, and lets you modify the plan at any stage for full developer control. In 2026, Jules expanded with a command-line interface (Jules Tools) and a Jules API, making it composable with CI/CD pipelines, Slack bots, and other custom developer workflows. The agent also features memory that remembers your preferences across sessions and environment snapshots that reuse prior setups so new tasks on the same repository start faster.
