Step 1 — Add the script to your frontend project

Sanity is a headless CMS, so the script is added in your frontend code, not inside Sanity Studio.

If your frontend is Next.js:

  1. Open the app/layout.js or pages/_document.js file (depending on your setup).
  2. Inside the <head> section, paste your FastBots script code:

    <script defer src="https://app.fastbots.ai/embed.js" data-bot-id="YOUR-BOT-ID"></script>

  Enable and test voice In FastBots, open Deployment → Chat Widget → Conversation Options. Choose Text and Voice or Voice Only, configure your voice settings and select Save Changes.   After installation, open your website or shared chatbot link as a visitor. Start a voice conversation, allow microphone access and check that you can hear a reply. If you enabled text fallback, check Type instead too. Voice tests consume message credits.   See the Chat Widget and Voice guide for the full setup. The setup wizard still creates a text chatbot; voice is enabled afterwards.
