What is an AI chat widget for Sanity?

For Sanity site owners, an AI chat widget is the fastest conversion improvement you can ship this week. While the rest of your site converts maybe 1 to 2 percent of visitors passively, the widget engages every visitor the moment they arrive, answers their questions instantly, and either books them in or captures their contact details. SmartWidget on Sanity installs in five minutes via a single JavaScript snippet pasted into frontend integration body insertion point.

Install steps for Sanity

The full install end-to-end. Five steps, about five minutes from signup to the first answered visitor.

  1. Sign up at smartwidget.co.uk. Enter your Sanity site URL. The AI reads your site and builds your knowledge base in about sixty seconds.
  2. Review the generated knowledge base. Check the question-and-answer pairs the AI has built. Edit or override anything that needs refining.
  3. Copy your install snippet. The SmartWidget dashboard shows a single script tag with your unique widget key.
  4. Paste the snippet into your Sanity site. Navigate to frontend integration body insertion point. Paste the snippet there and save. The widget is live the moment the page saves.

The dashboard you'll use on Sanity

The SmartWidget setup dashboard is where you review and refine the AI receptionist for your Sanity site. The AI reads your site during signup, builds a draft set of question-and-answer pairs, and presents them in the dashboard for review. You edit anything that needs refining, add answers to gaps, set the tone of voice, and configure escalation rules. The dashboard is where the AI is shaped to match your specific Sanity business — services, prices, opening hours, the way you handle out-of-hours enquiries.

Why an AI chat widget matters on Sanity sites

AI chat widgets on Sanity sites win not because they replace human chat — they don't, you still take over for complex cases — but because they make sure every visitor gets answered. Most chat tools fail because they can't be staffed 24/7. The widget fixes that constraint. Install on Sanity in five minutes from frontend integration body insertion point. £19/mo. Human takeover available any time.

Manage every Sanity conversation in one inbox

The dashboard you'll spend most of your time in is the messaging inbox. It shows every conversation the AI has on your Sanity site, lets you jump into any live one with one click, and keeps a searchable archive of every conversation the widget has ever had. Visitor contact details from every qualified conversation are captured automatically. Most Sanity businesses check this inbox once a day and the AI handles the rest 24/7.

Frequently asked questions

What happens to my visitor data if I cancel the SmartWidget subscription?

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 Sanity site stops loading immediately on cancellation.

Will the SmartWidget snippet affect my Core Web Vitals on Sanity?

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 Sanity site typically shows zero score change.

Can the SmartWidget AI escalate to me by WhatsApp on Sanity?

Yes. The dashboard supports WhatsApp Business API integration for escalations. When the AI flags a high-intent enquiry on your Sanity 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.

How long does it take to install SmartWidget on Sanity?

The install on Sanity takes about five minutes end-to-end. You sign up at smartwidget.co.uk, paste your Sanity site URL so the AI can read it, review the auto-generated answers, copy the JavaScript snippet, paste it into frontend integration body insertion point, and save. The widget is live and answering visitors the moment the page saves.

Do I need a developer to install SmartWidget on Sanity?

No. The Sanity install is one line of JavaScript pasted into frontend integration body insertion point. If you can navigate your Sanity admin dashboard, you can complete the install. The walkthrough on the SmartWidget dashboard shows the exact menu path for Sanity with screenshots.

Will SmartWidget conflict with my Sanity theme or other scripts?

No. SmartWidget loads asynchronously and isolates its CSS inside a Shadow DOM, so it cannot affect your Sanity theme's styling, animations, or layout. It also does not block page rendering. Lighthouse and PageSpeed scores are unaffected.

Does SmartWidget work on every Sanity plan?

Yes for any Sanity plan that lets you paste a script tag or custom JavaScript into frontend integration body insertion point. On a small number of Sanity entry-level tiers the custom code feature is restricted; in that case upgrading to the next plan unlocks it. Most Sanity Business or Pro tiers and above support SmartWidget directly.

Is there a Sanity plugin I need to install?

No. There is no plugin for Sanity. SmartWidget installs via a single line of JavaScript pasted directly into frontend integration body insertion point. Avoiding the plugin route means fewer dependencies, zero conflicts with your other Sanity extensions, and no plugin marketplace approval process.

What does the SmartWidget snippet for Sanity actually look like?

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 frontend integration body insertion point, and save. The script tag loads our widget client asynchronously when a visitor lands on your page.

Will the widget slow down my Sanity site?

No. The widget loads asynchronously after the page has rendered, so it does not block any of your Sanity 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.

How does GDPR work with the SmartWidget install on Sanity?

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 Sanity cookie banner solutions, and the dashboard exposes the controls needed for data-subject access and deletion requests.

Can I customise the widget colours and position on Sanity?

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 Sanity site immediately.

How do I uninstall the widget from Sanity if I need to?

Remove the single line of JavaScript from frontend integration body insertion point and save. The widget disappears immediately. There is nothing else to uninstall from Sanity — no database tables, no orphaned files, no leftover configuration.

Can I run SmartWidget on multiple Sanity sites with one account?

Yes. Multi-site is built in from the Growth tier. One SmartWidget subscription can run widgets across multiple Sanity sites, each with its own AI personality, knowledge base and unified inbox. Particularly useful for agencies running client Sanity sites or operators with multiple brand sites.
