Jules is an AI coding agent announced in December 2024 and described as 'an AI coding assistant that can automatically fix software bugs and prepare code changes while developers sleep.'

Jules was released to a select group of trusted testers for nearly six months after its launch, but was finally released as a public beta in May 2025. Jules automates tasks like bug fixes, version number changes, and testing, allowing users to focus on what they want to do by leaving the tedious tasks to Jules.

Jules integrates with GitHub's workflow system and helps you import repositories, branch changes, and create PRs (pull requests). It also includes the ability to clone code in virtual machines in the cloud to ensure your changes work, and a test suite to run existing tests or create new ones.

Furthermore, Jules provides a 'plan' of what it will do before writing the code, so users can see the plan and follow Jules's direction, and even request revisions if necessary.

Jules is an asynchronous AI coding agent, so there's a user approval process before a pull request is actually submitted, and it also generates an audio summary of the changes.

On the same day, Google also announced Stitch, a tool that lets users design complex UIs based on simple prompts and images. Stitch leverages the multimodal capabilities of Gemini 2.5 Pro, and includes image input, interactive chat, theme settings, and the ability to embed into Figma.
