Five steps. The last one is yours.

From what your store knows to a widget that answers on its own, and knows when to stop.

  1. Add what you know

    Upload documents, FAQs and product information, or paste a page. On Shopify, your products, pages, blog posts and collections sync on their own. The AI answers from this and nothing else.

  2. Define the assistant and make it yours

    Give it a name, instructions and a tone. Match the widget to your brand with your colours, layout and suggested questions, and see the result live before it goes anywhere.

  3. Add it to your site

    One line of code on any website. On Shopify, install the app and turn on the theme embed. No developer needed either way.

    Add to your site
    Any website: paste one line before the closing body tag
    <script async src="https://widget.functional-ai.com/chatbot.js"

    Shopify: no code
    Install from the Shopify App Store
    Turn on the theme app embed. The widget appears on your storefront.

  4. Watch every conversation as it happens

    Each thread from your widget lands in one inbox. Read what the AI is saying in real time, and take over any conversation with one click.

  5. The AI stops. You step in.

    You write the conditions in plain language: a refund request, an angry customer, someone asking for a person. They are checked before the AI replies, so on a match it says nothing, the customer sees a handoff card, and the thread is waiting for you with the reason attached.

No. FunctionalAI runs as a chat widget on any website: paste one line of code and it's live. If you are on Shopify, install the app instead and your products, pages, blog posts and collections sync on their own.
