AI Search vs FiboSearch

Short answer: FiboSearch and AI Search solve different problems. FiboSearch gives your search bar an excellent instant, search-as-you-type experience. AI Search makes the results themselves smarter by adding semantic matching on top of the keyword results you already get. Many stores are well served by either – some by both.

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 takes a different approach: it does not touch your search box or add any UI. It works on the results – every product gets a semantic “meaning fingerprint”, and when keyword matching alone would miss relevant products, AI Search finds them by meaning. 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.

When to choose FiboSearch

Choose FiboSearch when the search experience is your bottleneck: you want a fast, polished dropdown with thumbnails and prices while the shopper types, and your customers generally know the words for what they want. It is a mature product with a large user base and it does this extremely well.

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, with a caveat. FiboSearch’s live dropdown uses its own engine, so AI Search does not influence those instant suggestions. AI Search enhances the standard results page (what shoppers see after pressing Enter). Stores that want FiboSearch’s typing experience and AI Search’s semantic recall on the full results page can run both side by side.

Bottom line

FiboSearch polishes how shoppers type. AI Search improves what they find. 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.
