Quarter

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.
