About cubic

cubic is an AI-based code review tool that integrates with GitHub and IDEs to review pull requests, flagging bugs, tech debt, and enforcing team coding rules with inline feedback. It generates AI-written PR summaries describing the impact of changes and offers one-click fixes for identified issues, ranging from simple automated commits to more complex fixes triggered manually.

The tool allows teams to define coding standards in plain English and adapts by learning from senior engineers' PR comment history. It can pull context from external tools including Linear, Jira, Notion, and Confluence. A separate scanning feature runs AI agents on a schedule or continuously against a codebase (outside of pull requests) to find bugs and security issues, triage them to the responsible owner, create tickets, and resolve those tickets automatically when a fix is merged.

Customers named on the page include Cal.com, n8n, Better Auth, and Browser Use. Installation is described as a "2 click install" with no credit card required for the free trial.
