Devin has introduced Devin Review, a tool designed to address the growing complexity and scale of code reviews as coding agents generate a surge of pull requests (PRs). This product leverages advanced AI and user experience design to support software engineers and maintainers facing increasingly unmanageable code diffs. Devin Review is currently in early release and available for free, targeting developers and teams who manage projects on GitHub. It can be accessed by anyone through a dedicated web app, by modifying PR URLs, or via a command-line tool, with public PRs requiring no login.

The solution organizes code changes intelligently, grouping related modifications and providing clear explanations for each section. It allows reviewers to interactively ask for additional context about code both inside and outside the PR without leaving the review environment. A standout capability is its AI-driven bug detection, which categorizes findings by severity, giving reviewers a prioritized list of issues to address. Unlike some automated tools, Devin Review integrates seamlessly into existing workflows and aims to reduce noise while increasing review accuracy.
Devin, the company responsible for this release, has positioned itself at the intersection of AI and developer tooling. Their move to focus on code review reflects feedback from their user base, who cite review bottlenecks as a major hurdle. Industry observers note that early testers appreciate the logical grouping of diffs and the actionable AI flags, while competitors are watching closely as AI-driven review tools become more prevalent in modern software development pipelines.
