# Compare issues and insights

> Use the Report class to compare issues that Project Auditor finds.

You can save the [`Report`](/engine/6000.6/script-reference/unity/projectauditor/editor/report.md) object produced by Project Auditor's analysis as a .projectauditor file, or examine it via its API. `Report` contains a `SessionInfo` object with information about the analysis session, including a copy of the `AnalysisParams` which Project Auditor used to configure the analysis. It also provides several methods to access the report's list of discovered `ReportItem` instances. Each `ReportItem` represents a single issue or insight: all the data for a single item in one of the tables that are available in the [Project Auditor window](/engine/6000.6/manual/analysis/project-auditor/window/reference.md).

The difference between issues and insights are that issues have a valid `DescriptorId` field and insights don't. There are a couple of ways to check this:

```c#
bool isIssue = reportItem.Id.IsValid();

// A slightly more readable alternative...
bool isIssue = reportItem.IsIssue();
```

If you have a valid `DescriptorId`, you can use it to get the corresponding `Descriptor`, which is the object that described a type of issue, including its details and recommendation strings.

```c#
var descriptor = reportItem.Id.GetDescriptor();
Debug.Log($"Id: {reportItem.Id.ToString()}");
Debug.Log($"Description: {descriptor.Description}");
Debug.Log($"Recommendation: {descriptor.Recommendation}");
```

Project Auditor also provides an API for creating custom analyzers tailored to the needs of your project. For more information, refer to [Create custom analyzers](/engine/6000.6/manual/analysis/project-auditor/programming/custom-analyzers.md).
