AI for code analysis

P4 Code Review enhances the code review process by using an AI model (similar to those from OpenAI) to generate explanations for code diffs in a file, making it easier for developers to understand and review changes.

Overview

You can send either the full diff of a file or a selected portion of code for AI code analysis.

To analyze the full diff, click the AI button in the file diff panel.

To analyze selected code:

• Select the code in the diff.

• Click the AI button .

A loading indicator appears while the analysis is generated.

The AI code analysis is returned as text in a pop window.

Only the following data is sent to the AI model:

• The file diff (or selected portion).

• The filename.

• The file extension.

P4 Code Review does not send the full file.

An AI Assistant is also available for comments on a review page. For details, see AI Assistant for comments.
