Review pull requests like you wrote them yourself
Haystack helps engineering teams manage the growing volume of AI-generated pull requests. It sits on top of GitHub, analyzes each PR’s diff, codebase context, agent trace, intent, and verification evidence, then routes it: safe to move forward, needs fixes, or needs human review. Teams use Haystack to keep code moving without rubber-stamping, focusing human attention where judgment actually matters.
Haystack uses AI-powered code reviews to guide reviewers through changes in logical order, enabling faster and more focused reviews that reduce the time from pull request to merge.
Haystack's AI organizes code changes logically, helping reviewers understand context and dependencies, which reduces missed issues and ensures comprehensive coverage of modifications.
Haystack provides consistent AI-guided review structure that helps teams follow a uniform approach to evaluating changes, reducing variability in review quality and thoroughness.
By presenting pull request changes in a structured, logical order rather than raw diffs, Haystack minimizes cognitive load and keeps reviewers focused on meaningful code analysis.
