How long does it take to add voice AI to Next.js?
Under 10 minutes. AnveVoice handles the AI complexity — you just sign up, train, and add the script using next/script or _document.tsx.

Yes. For App Router, use the next/script component in layout.tsx. For Pages Router, add the script tag in _document.tsx. Both approaches work seamlessly.

Can I use AnveVoice with server-side rendering in Next.js?
