Can I limit the number of links per post?

Yes. You can set both per-alias per-paragraph limits and a total links per post limit.

Will this plugin affect existing links?

No. The plugin skips text already inside <a> tags, so your manually added links remain untouched.

Does this work with custom post types?

Yes. It hooks into the_content, so any post type that uses it will be processed.

Is there a Pro version?

A Pro version is in development with additional features like exclusions, reporting, and faster processing.

  • Pro (AI Links): Smart Suggestions now runs on the full post/page in one request (no line-by-line paragraph scanning).
