Google has decided to shut down Jules, the artificial intelligence assistant it built to help software developers write and repair code, and to fold the lessons from that experiment into a single, larger coding platform called Antigravity. The move leaves developers who relied on Jules with a firm deadline to finish their work and save everything they still need.
The company has confirmed that Jules will stop operating entirely on December 31, 2026. Before that final closure, users will have until November 11 to complete any coding tasks still running on the platform. After that date, Jules will switch to a read-only mode, so people will still be able to look at their existing projects, but they will no longer be able to carry work forward through the service. The timetable leaves only a short window to close active sessions and export stored material.
Why Google Is Closing Jules
Google presented Jules as a different kind of coding helper. Instead of waiting for a programmer to type each instruction, Jules was designed to work on its own in the background. A developer could connect a GitHub repository, hand over a task, and then turn to other work while Jules examined the code, proposed changes, and prepared them for review. The idea was that routine jobs such as fixing bugs and preparing updates could be handled without constant supervision, freeing developers to concentrate on the harder design and judgement calls that machines still handle poorly.
Google launched Jules as an experiment in December 2024, opened it to a wider public beta in May 2025, and brought it out of beta in August 2025. Its closure therefore comes just over a year after it became widely available.
Google has described Jules as an experiment that taught the company a great deal about how AI agents can help people build software. In its announcement, the company said that experience is now shaping other products, above all Antigravity. It has not said how many people were actively using Jules, and it has not linked the closure to low usage, to a technical failure, or to a security problem. The explanation offered is one of focus: rather than maintaining several overlapping coding tools, Google wants to bring its efforts together in one place.
What Happens to Existing Jules Users
For people still using Jules, the practical question is what happens to their work. Google has set out two dates that matter above all others. The first, November 11, 2026, is the last day for completing ongoing coding sessions. Once that date passes, the platform becomes read-only, and no new work can be started or continued inside it. The second, December 31, 2026, is the day Jules shuts down completely.
To help users through that transition, Google has provided a way to export material stored inside Jules. Users can download their account settings, the repositories they connected, saved information, scheduled tasks, and setup instructions, along with the history of previous coding sessions. That history includes task instructions, the plans Jules drew up, logs of its activity, and the code changes it proposed. Google has stressed that code, branches, and pull requests already held on GitHub will remain available there after Jules closes, because that material lives on GitHub itself rather than inside Jules. Anything stored only within Jules, however, needs to be exported before the shutdown, or it will be lost when the service ends.
Google has not announced an automatic transfer of Jules projects into Antigravity, nor confirmed that every Jules feature will appear there, so developers will need to rebuild part of their workflow by hand.
Google Shifts Focus to Antigravity
Antigravity is the platform at the centre of Google’s new plan. Like Jules, it is designed to help developers manage coding tasks through AI agents and to reduce the amount of repetitive manual work involved in building software. The difference, as Google presents it, is one of scope: Antigravity is meant to be an agent-first development environment, a fuller workspace in which AI agents and human developers work side by side, rather than a single assistant handling tasks in the background.
That ambition places Google in direct competition with strong rivals including OpenAI’s Codex, Anthropic’s Claude Code, and GitHub Copilot. By gathering its coding work under one name, Google hopes to offer a more unified experience, but developers who invested time in Jules may be slower to trust its replacement, and Google has not yet said when Jules’s distinctive background-task features will arrive in Antigravity.
For now, the message to Jules users is simple and urgent: finish active projects by November 11, save everything stored inside Jules before the end of the year, and start testing a new workflow while there is still time. Whether Antigravity repays Google’s bet will depend on how well it carries forward what Jules taught the company, and on whether developers are willing to follow it to its next destination.
