PrestaShop lets you paste custom JavaScript into Custom HTML hooks in the front-office theme. SmartWidget uses exactly that mechanism — no plugin, no theme modification, no engineer. Five-minute install. £19 a month. Multi-site from the Growth tier. UK GDPR clean by design.
An AI chat widget for PrestaShop turns a passive site into an active sales tool. SmartWidget engages every visitor instantly, answers their questions about your services in real time, qualifies the enquiry against your business rules, and either books them in directly or alerts you on SMS when an urgent lead lands. The install is one line of JavaScript pasted into Custom HTML hooks in the front-office theme. Five minutes. £19/mo.
The full install end-to-end. Five steps, about five minutes from signup to the first answered visitor.
The exact panel and field to paste the snippet on every supported platform. PrestaShop is highlighted first.
Sign up SmartWidget for your PrestaShop site and the first thing you see is this dashboard. The AI has already read your site and built a draft receptionist. The dashboard shows you exactly what the AI thinks it knows — services, prices, opening hours, the qualifying questions a trained receptionist would ask — and lets you correct anything that needs correcting. Most PrestaShop businesses are confident enough to go live within twenty minutes of signup.
The reason UK PrestaShop businesses are adopting AI chat widgets in 2026 is straightforward: they work. Conversion uplift typically doubles on the same site traffic, the install is five minutes from Custom HTML hooks in the front-office theme, the cost is £19 a month, and the widget runs 24/7 with no operator labour. Monthly billing with no contract means the risk is small enough that the decision pays for itself in the first month.
This is the unified inbox for SmartWidget conversations across your PrestaShop site (and any other site you run the widget on). Multi-site agencies use this dashboard to manage conversations across dozens of client PrestaShop sites from one screen. Per-site filters, per-conversation tagging, full-text search across transcripts, conversation export, and direct integration with your PrestaShop calendar and CRM are all built in.
Conversation transcripts and visitor contact data are retained for 30 days after cancellation, then deleted permanently. Within that 30-day window you can export the full transcript archive and the contact database as CSV from the dashboard. The widget snippet on your PrestaShop site stops loading immediately on cancellation.
No. The widget loads asynchronously after the page has rendered. The bundle is under 30KB. There is no impact on Largest Contentful Paint, Cumulative Layout Shift, or First Input Delay. Lighthouse audit before and after the install on a PrestaShop site typically shows zero score change.
Yes. The dashboard supports WhatsApp Business API integration for escalations. When the AI flags a high-intent enquiry on your PrestaShop site, it can send you a WhatsApp message with the visitor's details and the conversation context. The integration runs on top of the standard email and SMS escalation options.
The install on PrestaShop takes about five minutes end-to-end. You sign up at smartwidget.co.uk, paste your PrestaShop site URL so the AI can read it, review the auto-generated answers, copy the JavaScript snippet, paste it into Custom HTML hooks in the front-office theme, and save. The widget is live and answering visitors the moment the page saves.
No. The PrestaShop install is one line of JavaScript pasted into Custom HTML hooks in the front-office theme. If you can navigate your PrestaShop admin dashboard, you can complete the install. The walkthrough on the SmartWidget dashboard shows the exact menu path for PrestaShop with screenshots.
No. SmartWidget loads asynchronously and isolates its CSS inside a Shadow DOM, so it cannot affect your PrestaShop theme's styling, animations, or layout. It also does not block page rendering. Lighthouse and PageSpeed scores are unaffected.
Yes for any PrestaShop plan that lets you paste a script tag or custom JavaScript into Custom HTML hooks in the front-office theme. On a small number of PrestaShop entry-level tiers the custom code feature is restricted; in that case upgrading to the next plan unlocks it. Most PrestaShop Business or Pro tiers and above support SmartWidget directly.
No. There is no plugin for PrestaShop. SmartWidget installs via a single line of JavaScript pasted directly into Custom HTML hooks in the front-office theme. Avoiding the plugin route means fewer dependencies, zero conflicts with your other PrestaShop extensions, and no plugin marketplace approval process.
A single script tag with your unique widget key. Around 200 characters total. You copy it from the SmartWidget dashboard after signup, paste it into Custom HTML hooks in the front-office theme, and save. The script tag loads our widget client asynchronously when a visitor lands on your page.
No. The widget loads asynchronously after the page has rendered, so it does not block any of your PrestaShop site's critical rendering path. PageSpeed and Lighthouse scores are unaffected. The widget bundle is under 30 KB and lazy-loads its UI when the visitor first interacts with the chat bubble.
SmartWidget is UK GDPR compliant by design. Conversation transcripts are encrypted at rest in UK-based data centres. The widget includes a configurable consent notice that integrates with most PrestaShop cookie banner solutions, and the dashboard exposes the controls needed for data-subject access and deletion requests.
Yes. The widget appearance is fully customisable from the SmartWidget dashboard — primary colour, accent colour, chat bubble position (bottom-left, bottom-right), avatar, welcome message, and trigger behaviour. The customisation is centralised, so changing it once updates the widget on your PrestaShop site immediately.
Remove the single line of JavaScript from Custom HTML hooks in the front-office theme and save. The widget disappears immediately. There is nothing else to uninstall from PrestaShop — no database tables, no orphaned files, no leftover configuration.
Yes. Multi-site is built in from the Growth tier. One SmartWidget subscription can run widgets across multiple PrestaShop sites, each with its own AI personality, knowledge base and unified inbox. Particularly useful for agencies running client PrestaShop sites or operators with multiple brand sites.
4.9 out of 5 from 199 reviews. A selection of install-experience reviews from real UK businesses.
My Bubble app site needed chat without breaking the app routing. SmartWidget installed as a body script in the Bubble SEO settings and works across every page of the app without intercepting any of the existing routing logic.
I work mainly in Webflow and I have tested every chat widget on the market for client sites. SmartWidget is the only one that does not introduce CLS issues. Clean install, perfect Lighthouse score.
My Shopify theme is custom and locked down. SmartWidget installs via theme.liquid before the body close — exactly where every other tracking pixel goes. Zero conflicts with my checkout.
I am the worst kind of non-technical user — I built my Squarespace site myself and was scared of the code injection field. The widget walkthrough showed me exactly which menu to open. I am live and capturing bookings.
My ConvertKit landing page was meant to be a temporary holding page that ended up running for two years. SmartWidget installed via the tracking code field and is now my main lead capture.
We run a Sitecore site for our manufacturing business. The IT team flagged compatibility concerns. SmartWidget installed as a layout-level script tag and passed the internal security review without modification.
