AI Search vs FiboSearch

Short answer: both give you a search-as-you-type dropdown. FiboSearch is the more mature, more configurable one. AI Search adds something FiboSearch does not do at all: it finds products by meaning, so shoppers who describe what they want in their own words still land on the right page.

What each plugin actually does

FiboSearch (formerly Ajax Search for WooCommerce) is one of the most popular WooCommerce search plugins, with over 100,000 active installs and years of refinement. Its core strength is the search box experience: an instant dropdown with live product suggestions, images and prices as the shopper types. It is fast, polished, and its free version is genuinely useful; the Pro version extends matching to SKUs, attributes, custom fields and more.

AI Search works on meaning. Every product gets a semantic “meaning fingerprint”, so a search for “warm jacket for hiking” surfaces your insulated trekking parka even if no product text contains the word “hiking”. Traditional keyword matches always rank first; semantic results are appended after them.

Since version 1.33 it also ships a search-as-you-type dropdown of its own, as two optional blocks. Keyword and SKU matches appear on every keystroke; the AI suggestions are added underneath when typing pauses. If you would rather not change your storefront at all, place no block – the plugin still improves your results page, and your theme’s search form stays exactly as it is.

When to choose FiboSearch

Choose FiboSearch when the dropdown itself is the product you are buying. It has had years of refinement and far more control over the details: layout variants, per-field weighting, search history, filters and much more configuration than our two blocks offer today. If your customers generally know the words for what they want, and you want to tune the typing experience precisely, FiboSearch does this better.

When to choose AI Search

Choose AI Search when the search results are your bottleneck: shoppers describe products in their own words (“something flowy for summer”), search in a different language, or hit empty result pages even though the product exists. AI Search fixes recall without changing anything about your storefront – and keyword matches keep top placement, so nothing you rely on today gets worse.

Can you run both?

Yes. FiboSearch’s dropdown uses its own engine, so AI Search does not influence those instant suggestions – but AI Search still improves the results page shoppers reach after pressing Enter. Run FiboSearch’s dropdown with AI Search’s semantic recall behind it, and simply do not place our blocks. Nothing conflicts.

Bottom line

FiboSearch gives you more control over how the dropdown looks and behaves. AI Search gives you a dropdown too, plus the thing keyword matching cannot do at any price: finding the product when the shopper does not use your words. If empty results and missed products are costing you sales, start with AI Search – it is free up to 10,000 products and reversible in one click.
