Biwem inc.

Biwem Search Autocomplete brings real-time, intelligent autocomplete suggestions to your WooCommerce store. Visitors find what they’re looking for in seconds — even if they misspell, abbreviate, or only know the SKU.
The plugin is built around four ideas:
<ol>
<li>Speed. Suggestions appear as the visitor types, with multi-level caching that keeps response times low even on shared hosting.</li>
<li>Forgiveness. Built-in fuzzy matching catches typos and missing letters automatically. Searching “trapno” still finds the trapano.</li>
<li>Smart matching. Beyond plain titles, the plugin also matches product SKUs and EAN/GTIN codes, so warehouse and B2B users find products by code instantly.</li>
<li>Compatibility. Works with any theme, any WooCommerce setup, any cache plugin. No assumptions about your stack.</li>
</ol>
<h4>What’s included</h4>
<ul>
<li>Real-time autocomplete suggestions in the search box</li>
<li>Configurable number of product / post / page suggestions per query (you choose how many)</li>
<li>Multilingual smart fuzzy matching — automatic typo recovery in English, Italian, Spanish, French, and German (handles missing letters, swapped letters, vowel substitution)</li>
<li>Automatic accent normalization — café/über/straße/niño/français all matched without typing the accents</li>
<li>SKU and EAN/GTIN exact match (a customer who knows the code finds the product immediately)</li>
<li>Multi-content search — products, blog posts, and pages in a single dropdown (toggle each independently)</li>
<li>Product thumbnails in the dropdown</li>
<li>Product price display with regular/sale formatting (uses WooCommerce currency settings)</li>
<li>Loading indicator while suggestions are fetched</li>
<li>Out-of-stock filter — hide unavailable products from suggestions</li>
<li>Multi-level caching (in-memory + 10-minute transient) for fast responses</li>
<li>Translation-ready (compatible with WPML, Polylang and Loco Translate)</li>
<li>5 bundled admin languages out of the box: English, Italian, Spanish, French, German</li>
<li>Works with any theme — no required modifications</li>
<li>Drop-in shortcode <code>[wcsa_search_autocomplete]</code> with 4 design styles</li>
</ul>
<h4>Privacy-first by design</h4>
This plugin makes zero external calls. Everything runs on your own server. No data is sent anywhere — ever.
<ul>
<li>No phone-home updates. Updates come from WordPress.org.</li>
<li>No usage tracking. No statistics, analytics, or telemetry are collected.</li>
<li>No GeoIP lookup. The plugin does not look up your visitors’ country.</li>
</ul>
The plugin is fully GDPR-friendly.
<h4>Pro version</h4>
A separate Pro version with advanced features is available at <a href="https://www.biwem.it/autocomplete" rel="nofollow ugc">https://www.biwem.it/autocomplete</a>. Pro features include:
<ul>
<li>SHORTINIT fast search engine (sub-50ms response times)</li>
<li>Real-time AI chat for natural-language product discovery</li>

<li>Category labels and breadcrumb in dropdown</li>

</ul>
The Pro version is distributed exclusively from biwem.it as a separate plugin (it is not hosted on WordPress.org). The Free version on WordPress.org remains fully functional and free forever.
<h3>External services</h3>
This plugin does not connect to, send data to, or rely on any external services. All functionality runs entirely on your own server:
<ul>
<li>Product search and SKU/EAN lookups are processed locally via WordPress’s own database. No third-party APIs are involved.</li>
<li>The plugin’s REST endpoint <code>/wp-json/wcsa/v1/suggestions</code> is internal — it is served by your own WordPress installation, on your own domain, and is called only by the front-end autocomplete script running in the visitor’s browser.</li>
</ul>
No analytics, no telemetry, no tracking, no remote calls of any kind.

<a href="https://www.neiltking.com/neuralnet/" rel="nofollow ugc">Related Posts Neural Network</a> learns what visitors access on your website and builds a locally stored Neural Network (Artificial Intelligence). This is then used to suggest other posts, pages or content on your site that visitors may like. You will have seen something similar on sites where they say “You may also like…” or “Other visitors were interested in…”.
Some key features include:
<ul>
<li>As it works by examining the URL, it will work with all content types in all languages which users may visit, for example articles, products, pages, blog posts, courses, photo galleries etc.</li>
<li>No visitor statistics or data leaves your website. Nothing is processed externally. Everything is done locally using no third party services. The custom written A.I. is built entirely within the plugin.</li>
<li>The plugin is written to be efficient so there should not be any noticable affect on the speed of your website.</li>
<li>No identifiable or personal information is collected from your visitors helping it abide by GDPR and privacy rules.</li>
<li>It is easy to install and set up for pretty much any WordPress site.</li>
<li>Works with the Gutenberg Block editor and Classic editor, and should work with any theme.</li>
<li>Insert suggestions anywhere in your site with the simple shortcode [rpnnrecommend]. You can adjust how it appears by adding parameters like [rpnnrecommend total=”6″ thumbnails=”false” class=”recommendedlist” title=”You might like…”] which would suggest six items the visitor might also be interested in, without featured image thumbnails, and assign the CSS class called “recommendedlist” to it.</li>
</ul>
The FREE version is limited to 30 synapses/paths/links between content, and the charts will only show up to 30 links and 10 items (e.g. pages). It is designed for you to try the plugin and decide if you like it and want to unlock the PRO version, but you can use the free version for as long as you like – there are no time limits. For small sites you may never need to upgrade.
To unlock the PRO version of the plugin, follow the link in the plugin settings. Here are some of the benefits you would receive:
<ul>
<li>Unlimited Neural Net size and number of synapses/paths (within database and your server limitations).</li>
<li>Neural Network graph increases from showing 10 nodes to 500, and from 30 synapses/paths/links to 1500.</li>
<li>The ability to manually adjust the weight/prominence of links between urls to help force or discourage certain recommended links.</li>
<li>Automatically downloads a list of common search engine bots/crawlers to block and prevent them from affecting the neural network.</li>
<li>A list of bad IP addresses is automatically downloaded to block any known misbehaving users from affecting the neural net.</li>
<li>Email support and help if needed.</li>
</ul>

<h3>Third Party Libraries and Links</h3>
The plugin uses 2 third party libraries which are included within the plugin so they do not need to be called from external sources (for security). They are only accessed by site administrators when they view the statistics tab inside the plugin settings area. Both of these javascript libraries are obfuscated to make the files smaller and faster to load. They are: 
* Chart.js – https://www.chartjs.org – MIT License – Full source available from: https://github.com/chartjs/Chart.js 
* Vis.js (network) – https://visjs.org – APACHE 2.0 License – Full source available from: https://github.com/visjs/vis-network
The plugin also talks to my server in order to check if the Pro licensed features should be unlocked and to download updated block-lists for search engine bots and bad IP addresses. The information it passes to the server is: 
* A unique ID number for your website (containing no personal or private information) 
* The host URL of your website in case the website or plugin gets re-installed so it can retrieve your unique ID number.
Communication with my server occurs once when the plugin is activated, then twice a day. It is also checked when the plugin settings page is accessed. This is purely to unlock the Pro features as soon as possible after purchase.
