Atlassian launches AI Code Reviewer for Jira and Bitbucket

Atlassian has announced the general availability of Code Reviewer, an AI agent designed to assist with pull request reviews within Bitbucket Cloud and GitHub. The tool is included with paid Jira and Teamwork Collection licenses.

The release addresses increasing pressure on software development lifecycles caused by the rise of AI coding agents. According to Atlassian’s Q3 State of AI Impact in Engineering Report, teams using AI to write code have seen pull request wait times increase from 32 to 71 minutes, while median pull request sizes have more than doubled from 46 to 102 lines of code.

Code Reviewer functions by providing an initial review that flags bugs, logic errors, security risks, and maintainability issues. It also checks pull requests against acceptance criteria in linked Jira work items and provides summaries for large changes. The tool includes a quality filter to remove low-value comments. Atlassian reports that internal implementation of the tool has reduced median pull request cycle time by 31%.
