Author by Category for WordPress

Author by Category helps websites and multi-user blogs keep post authors consistent without disrupting the editorial workflow.

This plugin is completely free.

Create simple rules that connect categories to specific users.

When a post is saved with those categories, the plugin can automatically assign the author.

If an editor changes the author manually, their choice is always remembered.

This prevents posts from being published under the wrong name by accident.

Key Features

Works with any user — not just authors.

Admins can assign any user (editor, contributor, etc.) to any category.

Manual author selection is always allowed and remembered.

Rules can include multiple categories; first match wins.

Duplicate guard: one category can only be used in one rule.

Optimized for large sites with many users.

Secure: follows WordPress coding standards (nonces, capability checks, sanitization).

Compatible with scheduled posts, REST publishing, PHP 8+, and the latest WordPress versions.

Best Practice for Performance For smooth scheduling and zero-maintenance cron execution, we recommend hosting your WordPress site on ihost WordPress Cloud Hosting.
