Google's AI coding tool to stop working from December 31: Why is the company shutting down 'Jules'?
Google has decided to shut down its AI coding tool, Jules. The service will be discontinued entirely on December 31, 2026. Prior to this, starting November 11, 2026, Jules will transition to a "read-only" mode; while users will still be able to view their past sessions, they will no longer be able to make any new changes. Developers who rely on Jules for their daily coding tasks should ensure they save any essential data well in advance.
The company intends to integrate the technology and insights gained from Jules into its other AI development platform, Antigravity. Google’s goal is to consolidate various AI coding tools into a single, unified platform where developers can access a wide range of features in one place.
**Jules to be phased out in two stages**
Rather than shutting down Jules abruptly, Google has established a clear timeline. As of November 11, 2026, the tool will enter read-only mode. During this period, users can access their previous coding sessions and related data, but they will not be able to initiate any new work. The service will then be fully discontinued on December 31, 2026. Consequently, users with incomplete projects or important coding sessions on Jules are advised to finalize their work before November.
**Why is Google shutting down Jules?**
Google has not cited any technical glitches or security concerns as the reason for this decision. Instead, the company is focusing on consolidating its AI coding services onto a single platform. According to Google, the experiments conducted with Jules provided valuable insights into how AI agents can help reduce the daily workload of developers. The company now aims to leverage this experience within Antigravity, ensuring that developers no longer need to rely on multiple, separate tools for coding and other development tasks.
What could developers do with Jules?
Launch: Jules was introduced in December 2024 as an experimental project from Google Labs.
GitHub Integration: Developers could connect their GitHub accounts and code repositories to it.
Coding Assistance: It could assist with tasks such as fixing code errors, building new features, and updating software packages.
Testing and Pull Requests: Jules could create and execute code tests and submit pull requests to GitHub once a task was completed.
Background Operation: It could continue working autonomously after receiving instructions from the user; developers did not need to remain at their screens to monitor its progress.
How can users keep their data secure?
Google is providing users with the option to download information related to Jules. This includes account settings, environment variables, saved memory, past sessions, prompts, activity logs, and changes made to the code. This can be done using the Jules command-line tool. Users need not worry about their actual source code; their code, branches, and pull requests already reside on GitHub and will remain secure there even after Jules is discontinued. The primary purpose of this data export is to preserve information that was stored specifically within Jules.
Similar capabilities available in AntiGravity
Google is now encouraging developers to use AntiGravity—a platform where AI agents can assist with tasks ranging from planning and modifying code to executing commands and verifying the results. The company plans to incorporate Jules’s background-operation capabilities into AntiGravity as well. However, it cannot currently be considered a direct, one-to-one replacement for Jules; therefore, users should be prepared to adapt their workflows to this new platform.
