Two word libraries
Run two independent sets — say, one per site section or client — and switch between them right in the editor sidebar.
Pro Add-on
Build links to your affiliate and Amazon pages in seconds.
Save the words and links you reuse often — Amazon and affiliate links especially — then spot them highlighted wherever they appear in a post and drop in the right link in a click.
✓ Requires the free base plugin
✓ Doesn't rewrite your content

We tested the Wireless Earbuds X against the Noise-Canceling Headphones Y — and why the Budget Earbuds Z is worth skipping.

Features
Everything you need to manage a lot of links.
Two libraries, five colors, and bulk tools — built for sites with more affiliate and Amazon links than a single list can hold.
Two link libraries
A second reference list of links, so two different projects or categories don't have to share one long list.
Five highlight colors
Yellow, green, red, blue, and orange — enough categories for a real workflow, not just "linked" vs "not linked."
CSV import & export
Bring an existing glossary in, or move your libraries between sites, in a couple of clicks.
Library set switcher
Flip between Set 1 and Set 2 directly from the sidebar panel while writing — no trip to Settings required.
Frontend preview toggle
Check the live post as a reader would, then flip highlights back on to confirm every mention is linked before you publish.

How to use
Get started in 3 simple steps.
Configure your libraries
Word libraries: go to Settings → Word Highlighter → Word Library to add words or phrases to Set 1 or Set 2. Optionally assign a category and one of five colors.
Link libraries: go to the Link Library tab to add reference URLs to either set. Optionally assign a category.
Use the editor
Your libraries appear in the sidebar of any post or page. Check a word to highlight every occurrence of it in the post.
Add new words or filter the list down to one category, right from that same sidebar panel.
Copy links instantly
Click any link's URL button in the sidebar panel to copy it straight to your clipboard.
Note: highlights are visual-only and never change
your saved post content. Which words are checked on for a post is
remembered per post, though — uncheck any you don't want showing
the next time this post is opened or previewed.

Questions
Frequently asked
Who can manage the libraries?
Site administrators edit word and link libraries under Settings → Word Highlighter. Editors can still enable highlights per post from the sidebar panel.
Do highlights change my post content?
No. In the editor they're drawn as overlays. On the frontend, marks appear only for logged-in users who can edit posts, and are never saved into the post.
Does it insert the affiliate link for me?
No — it doesn't auto-insert anchor tags. It highlights the words you've flagged and keeps your links in a quick-reference library, so finding the right URL and adding it yourself takes seconds instead of a search.
Does it help with affiliate disclosure requirements?
Not automatically — it won't add disclosure text for you. Many sites use one highlight color as a visual reminder to check disclosure and link freshness before publishing.
Do I need the free plugin too?
Yes — Pro is an add-on that requires the free Post Word Highlighter plugin installed and active. It adds the second library, extra colors, and CSV tools on top of it.
What payment methods are accepted?
Checkout is handled securely through PayPal. Your payment details are never seen or stored by us directly.
Do I get updates and support?
Yes — your purchase includes plugin updates and email support for as long as your license is active.
Where do I get support?
Email [email protected] for Pro support, or use the WordPress.org support forum for free-plugin questions.
