Google is expanding the reach of its AI coding agent Jules by introducing a command-line interface (CLI) and a public API, allowing developers to integrate the tool directly into their terminals, CI/CD pipelines, and even apps like Slack. The move underscores Google’s push to make coding a more AI-assisted task as competition heats up in the developer tools space.
Until now, Jules was only accessible via its website and GitHub. The new Jules Tools CLI lets developers interact with the agent through simple commands, reducing the need for constant context switching between platforms.
“We want to reduce context switching for developers as much as possible,” said Kathy Korevec, director of product at Google Labs.
Both Jules Tools and Google’s Gemini CLI run on the Gemini 2.5 Pro AI model, but Korevec explained that Jules is designed for “very scoped tasks,” while Gemini CLI is more iterative and collaborative.
In addition to the CLI, Google has made Jules’ API publicly available. This allows developers to integrate Jules into their existing workflows or connect it with their preferred IDEs, like VS Code. Korevec added that Google is also exploring official plug-ins for IDEs to deepen Jules’ integration.
The launch follows several recent upgrades to Jules, including memory features for personalized interactions, an improved diff viewer layout, image upload support, and the ability to respond to pull request comments. Google is also considering ways to reduce Jules’ dependency on GitHub by supporting other code hosting providers.
Oversight remains a key consideration: Jules notifies users when it encounters a problem, though Google acknowledges challenges in providing the same level of feedback on mobile, where native notifications are not yet supported.

Since its public preview in May, Jules has attracted primarily professional developers but is also being used by hobbyists who want to extend projects beyond casual “vibe coding” platforms. The service exited beta in August and is now available under structured pricing tiers:
- Free plan: up to 15 daily tasks, 3 concurrent tasks
- AI Pro ($19.99/month): ~5x higher limits
- AI Ultra ($124.99/month): ~20x higher limits
With Jules Tools, Google is positioning its AI agent to become a core part of developers’ daily workflow, from terminals to CI/CD pipelines and beyond.
