cubic
cubic reviews pull requests in GitHub and your IDE, enforces rules written in plain English, and learns from senior engineers' PR comment history. It runs thousands of agents nightly to scan an entire codebase for bugs, pulls context from Linear, JIRA, Notion and Confluence, and is free for public repositories.
- Plain-English rules capture standards that no linter syntax can express
- Learning from past review comments surfaces conventions nobody wrote down
- Reviewing in the IDE catches issues before a pull request exists
- Pulling context from issue trackers means review sees intent, not just diff
- Learned conventions inherit whatever was outdated or wrong in the history
- How seniority is determined is unstated and materially affects what it learns
- Natural-language rules are interpreted, so occasional inconsistency is inherent
Korbit AI
Korbit AI is an automated code-review tool that reviews pull requests inside GitHub, GitLab and Bitbucket, flagging bugs, security and design issues with fix explanations, writing PR descriptions and summaries, and generating team insights, without training on your code.
- Reviews inside the PR where work already happens
- Explains fixes, doubling as a training aid
- Automates PR descriptions and summaries
- Clear no-training-on-your-code commitment
- Initial false positives need tuning out
- Does not replace human review
- Limited value for solo developers
