What cubic is
cubic is an AI code review platform that plugs into GitHub. When a pull request opens, it reviews the diff against your team's guidelines and best practices and leaves inline comments within seconds. It can also accept simple fixes in one click, draft the PR description for you, and learn your codebase so its suggestions match house style rather than generic advice.
What you can do with it
- Review pull requests automatically against your own rules.
- Get inline feedback on each PR within seconds.
- Accept simple fixes in one click, or hand complex issues to a background agent.
- Generate PR descriptions that explain the change and its impact.
- Enforce style guides and custom rules across the repository.
- Connect Jira, Linear or Asana to keep work items in sync.
Who it is for
Software development teams where review is a bottleneck, individual developers who want a second pass before requesting review, and enterprise projects that need consistent standards across many repositories.
What to watch out for
The free tier is capped at forty reviews a month and five custom rules, so real teams will pay. AI review catches a class of problems, not all of them, and it should sit alongside human review rather than replace it. You are also granting a third party access to source code, so read the data handling and SOC 2 claims carefully before connecting private repositories. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data.
