Quarter is an AI engineer that works directly with your code repository like a full team member. It understands your project structure and delivers changes as a pull request (PR) you can review and merge through your normal workflow.
Autonomous repo work
Give Quarter a task and it will:
- Clone the repository
- Index files and locate relevant code
- Implement changes in the codebase
- Create a PR for standard review and approval
End-to-end engineering tasks
Quarter can take on common, repeatable development work, including:
- Writing tests
- Implementing typical features and utilities
- Refactoring existing code
- Adding CRUD endpoints
- Updating documentation
PR review follow-up
After opening a PR, Quarter can continue the loop by responding to reviewer comments and updating the code based on feedback. This helps reduce back-and-forth and speeds up reviews.
Built for large codebases
Quarter is designed for repositories with thousands of files, working with project-wide context rather than isolated snippets—useful for product teams that want faster delivery without changing their process.
