Let visitors talk to your website

Stelt adds a voice-capable AI assistant to your business website — trained on your own information. Visitors ask a question in their own words, by voice or by typing, and get a spoken answer right there on the page.

What a visitor experiences

From the visitor’s side there’s no app and nothing to learn — they just ask, the way they’d ask a person who works there.

  1. Visitor asks

    They tap the mic and speak, or type — in their own words, not keywords.

  2. Stelt understands

    It works out what they mean and finds the answer in your business information.

  3. Answers out loud

    A natural spoken reply (and on-screen text), in the voice you chose.

  4. Shows when useful

    It can pull up a relevant page, video or document to go with the answer.

  5. Continues naturally

    They ask a follow-up, or move on to an inquiry — all in one conversation.

More than a talking chatbot

Voice is only useful when the assistant actually knows your business. A general AI can talk, but it doesn’t know your prices, your service area, or your policies. Stelt does — because it answers from what you give it.

This isn’t the full rundown of voice versus a rule-based bot — for that, see voice AI vs chatbot.

Where the answers come from

Willow’s answers are grounded in material you supply, so they stay accurate and on-brand — she works from your content rather than the open internet.

You can train her from a single web page, a whole-site crawl, uploaded documents, and notes you type in. When a visitor asks something you haven’t covered, that’s your cue to add it. More on this in Knowledge & Training.

Voice that starts responding naturally

When a visitor asks something, Stelt doesn’t wait to finish the whole answer before speaking. The response streams and is split into sentences, so the spoken reply can begin on the first sentence while the rest is still being written — which keeps the conversation feeling responsive.

  1. Visitor speaks or types
  2. Stelt works out the answer
  3. The reply streams back
  4. Speech begins sentence by sentence

You choose how it sounds: premium Google voices when you’ve added a Google key, or a free built-in browser voice with no key at all. Either way, typing is always available too.

Sometimes the best answer is something to see

Some questions are answered fastest by showing, not just telling. Alongside speaking, Willow can bring a relevant video, image, document, a specific page of your site, or an embed up on screen — right in the conversation.

From conversation to inquiry

A useful conversation often ends in a lead. When a visitor is ready, Willow can present a short contact form you’ve configured, and the submitted inquiry reaches your Stelt dashboard for your team to follow up. (She presents the form — the visitor fills it in.)

Works with the website you already have

Adding Stelt is one line of code before your closing body tag — no rebuild, no plugin, on virtually any platform:

<script src="https://stelt.ai/widget.js" data-business="YOUR_BUSINESS_ID"></script>

Grab your own snippet from the dashboard. On WordPress, follow the WordPress guide, and see the website widget for how it fits your site. No website to embed on? Stelt also has a standalone assistant page you can share by link.

Voice when they want it, typing when they don’t

Voice is an option for the visitor, never a requirement. A few honest expectations:

So visitors who want to talk can, and everyone else simply types — nobody is blocked from getting an answer.

Who it’s useful for

Frequently asked questions

What is website voice AI?

It’s an AI assistant on your website that a visitor can talk to — they ask a question out loud (or by typing) and hear a spoken answer. With Stelt the assistant is Willow, trained on your own business information, added with one line of code.

Can visitors type instead of talking?

Yes. Every visitor can type in the same box, or tap the mic and speak — and switch between them mid-conversation. No one is ever forced to use their voice.

Where does Stelt get its answers?

Only from the material you train it on — your website pages, uploaded documents (PDF/DOCX), and notes you add. It answers from your content rather than inventing information, and hands off to your team when something is outside what it knows.

Can Stelt show visitors videos or documents?

Yes. Alongside the spoken answer, Willow can bring a relevant page, video, image, document, or an embed up on screen — see Show on Screen.

Can Stelt capture contact information?

Yes. When a visitor is interested, Willow can present a short inquiry form you’ve configured; submitted inquiries land in your Stelt dashboard for a person to follow up.

Does my website need to be rebuilt?

No. Stelt is a single line of code placed before your closing body tag. It works on top of your existing site, on virtually any platform — no rebuild and no plugin required.

Does the microphone work on every website and browser?

Voice input uses the browser’s own speech recognition, which some browsers and in-app webviews don’t provide, and the microphone requires a secure (HTTPS) page. Where the mic isn’t available, typing always works — so no visitor is left without a way to ask.

Can Stelt work without being embedded on a website?

Yes. As well as the embeddable widget, Stelt offers a standalone assistant page you can share by link — useful when there’s no site to embed on.
