Show HN: Diffity – Mac App for Reviewing Diffs (diffity.com)

Diffity has launched a new Mac application designed to streamline the code review process by mimicking GitHub's pull request interface. Users can easily review code changes, leave comments on specific lines, and send those comments to AI agents like Claude Code or Codex for modifications. This integration allows the AI to address each comment sequentially, enhancing collaboration and productivity in code reviews. This innovation is significant for the AI/ML community as it leverages the capabilities of large language models to provide real-time feedback and make code changes, which can improve the efficiency of developers. Diffity supports various agents, allowing users to select the model and adjust the effort level for their specific needs. Moreover, the app facilitates smooth navigation through commits and pull requests while ensuring that all comments remain linked to respective branches. By enabling seamless integration with GitHub and quick access through terminal commands, Diffity not only enhances the review process but also positions itself as a valuable tool for software development teams looking to incorporate AI into their workflows.
