Semantic Search
AI understands intent, not just keywords. "healthy proteins" finds your articles about chicken and salmon. "do you ship overseas" finds your international shipping page, even if no page is titled that.
WordPress Search Intelligence
Your visitors are searching. Do you know what they can't find?
LucidSearch replaces WordPress's broken keyword search with semantic AI, then shows you exactly where it's failing your visitors, so you can fix it.

The problem
Default WordPress search hasn't improved since 2003.
It matches keywords, not meaning. Your visitors pay the price — and so do you.
Default WordPress search
gift cards
- "10 Gift Ideas for Spring" keyword match: "gift"
- "Card Making for Beginners" keyword match: "card"
- Nothing your visitor actually wanted
A ready-to-buy visitor bounces. You never know it happened.
With LucidSearch
gift cards
- "Buy a Gift Card — Instant Delivery" semantic match: 98%
- "Gift Card Balance & Terms" semantic match: 94%
- "Corporate & Bulk Gift Card Orders" semantic match: 87%
Visitor finds it — and checks out.
What WordPress doesn't reveal: your site is full of searches that return zero results. Every one is a visitor who left. Until now, you had no way to see them.
What you get
Search that works. Insight that compounds.
AI Answers
Don't just list links — answer the question. LucidSearch writes a concise answer at the top of the results, sourced entirely from your own content. Like Google's AI overviews, but for your site.
Search Analytics
See every query your visitors type. Spot zero-result failures. Watch search volume over time. Understand exactly what content your site is missing.
Zero-Result Alerts
The most actionable insight in search: queries that returned nothing. Get notified automatically and turn each one into a content opportunity or a redirect.
WooCommerce Attribution
Connect search queries to purchases. See which searches lead to conversions, and which product searches fall flat.
Agency Dashboard
Manage search across all your client sites from one place. Export reports. Show clients the value of better search.
Easy Setup
One-click install. Drop in a shortcode or use the widget. Works with any WordPress theme — no code required.
The differentiator
Most search plugins stop at "better results."
LucidSearch tells you what's missing.
Every zero-result query is a visitor asking a question you haven't answered yet. That's not just search — that's content strategy.

For WooCommerce stores
Your store's search is losing you sales.
- Shoppers who use site search convert at 3–5× the rate of those who don't.
- Zero-result searches in a store mean lost revenue, not just lost engagement.
- LucidSearch connects search queries to purchases, so you can see the gap and close it.

What people are saying
"The zero-result report paid for itself in the first week. We found 47 searches for a policy page we didn't have, published it, and support tickets dropped noticeably."
"I installed it on a recipe blog with 2,000 posts. Visitors searching 'quick dinner' finally get quick dinner recipes instead of a keyword lottery. Search-driven pageviews are up 22%."
"We rolled it out across nine client sites. The client-facing reports are the first time we've been able to show search as a measurable win in our monthly retainer reviews."
FAQ
Questions, answered.
Does LucidSearch replace my existing WordPress search?
Yes, seamlessly. LucidSearch takes over your theme's search form and results automatically — no template edits needed. You can also place it anywhere with a shortcode or widget.
What's the difference between the free version and paid?
The free version includes real semantic AI search — genuinely better results than default WordPress search, forever, on your 75 most recent posts. Paid plans unlock the intelligence layer: full search analytics, zero-result alerts, AI Answers, unlimited indexing, and branding removal.
Can I try before buying?
Yes — automatically. Every install starts with 14 days of full Pro, no credit card required. When the trial ends you keep the free plan forever, real semantic search included, and can upgrade whenever you want the full picture back.
What happens when my Pro trial ends?
Nothing breaks — search keeps working. Your index keeps your 75 most recent posts, AI Answers turns off, analytics shows your top 5 searches, and the "Powered by LucidSearch" footer returns. The plugin warns you during the final 3 days, and you can upgrade anytime to pick up right where you left off.
Does it work with WooCommerce?
Yes. Product search works on all plans. The Pro plan adds search-to-purchase attribution, so you can see which searches lead to orders — and which product searches return nothing.
What happens if I have more than 75 posts on the free plan?
There are no search-count limits on any plan. On Free, your 75 most recent posts are indexed and searchable — older posts simply aren't included in results, and the plugin shows an upgrade notice. Pro indexes everything.
Is my data sent to an LLM?
Your published post content is sent to an LLM to generate embeddings (the mathematical representations that power semantic search). No visitor personal data is ever sent — search queries are processed and stored in your own analytics, not used to train any AI models.
Does it work with my theme?
Yes — LucidSearch works with any WordPress theme via automatic integration, shortcode, or widget. It inherits your theme's styling by default.
What counts as a "search"?
Each query a visitor submits counts as one search. Typing suggestions and refinements within the same search session don't multiply the count unfairly.
Can I switch plans later?
Yes, anytime. Upgrades take effect immediately; downgrades apply at the end of your billing period. Your analytics history is preserved.
Do you offer refunds?
Yes — all paid plans come with a 14-day money-back guarantee, handled securely through Freemius, our checkout provider.
Will it slow down my site?
No. Search runs on our infrastructure so results are fast even on shared hosting, and your site's performance is untouched.

One flat subscription covers 15 client site installs. You manage everything from a centralized dashboard.
