cubic is an AI code reviewer for complex codebases. It’s used by top engineering teams at n8n, Cal.com, Resend, and more. Code review is a major bottleneck for software teams, and the rise of AI-generated code is making the problem worse. Reviewing large volumes of code slows devs down, and increases the chances of bugs slipping through. That's why we're building cubic: an AI code reviewer designed for complex codebases. Teams who adopt cubic merge merge PRs 48% faster. How? When you open a PR, cubic automatically reviews it. It learns from your codebase's patterns, points out bugs, suggesting fixes, and frees you from low-level review tasks.
