URL Autolinker by Jerin.ca automatically converts your saved keywords (aliases) into links inside your content. 
Add a URL, assign one or more aliases, and the plugin will link those aliases when they appear in your posts/pages. 
Each saved URL can have its own link behavior (open in a new tab, nofollow), and you can export/import your Saved URLs to move rules between sites.
If you want advanced controls and AI-powered internal-link suggestions, an optional Pro upgrade is available. 
Pro adds powerful content controls, exclusions, limits, performance options, and AI Links (Smart Suggestions + Zero-Link Posts) so you can plan internal linking faster.
Free Features: 
– Save URLs with one or more aliases (keywords). 
– Automatically link aliases to the saved URLs in post content. 
– Per-link options: open links in a new tab, add nofollow. 
– Export and import your Saved URLs.
Pro Features (Available Now): 
– Link limits (per-alias per-paragraph, and total links per post). 
– Post type whitelist + post/page blacklist controls. 
– Exclude HTML areas (headings, lists, tables, code, etc.). 
– Optional: skip targets already linked manually. 
– Optional: cache compiled rules for faster performance. 
– AI Links: Smart Suggestions — analyzes a full post/page and suggests internal links (target + anchor words). 
– AI Links: Zero-Link Posts — helps identify posts/pages that likely need internal links. 
– Review-first workflow — you choose what to save/apply. 
– Save selected AI suggestions into Saved URLs for consistent auto-link rules. 
– License status + Pro enable/disable toggle.
