While working in the CAT editor, Auto QA automatically detects potential issues in your translations. This reference guide provides a complete list of error codes, descriptions, and messages that may appear while using Auto QA.

Error categories
Auto QA errors are organized into 4 main categories:
- Spelling: Identifies spelling issues
- Segment and terms: Checks translation consistency, terminology, and segment-level issues
- Inline tags: Validates proper tag formatting and placement
- Consistency: Ensures consistent translations across your project
