AI CO-BROWSING GUIDE

The AI that goes before
your users

Harbinger reads the page, understands the context, and guides every visitor with an AI assistant that knows your product as well as you do. One script tag. Done.

Three lines. Infinite context.

1

Embed the widget

Add one script tag to your site. Harbinger loads in under 8KB and renders inside a shadow DOM — zero style conflicts.

2

Teach it your product

Upload docs, FAQs, or markdown to the knowledge base. Harbinger builds a vector index and retrieves the right context for every question.

3

Guide every visitor

Harbinger reads the current page, matches it to your knowledge base, and answers questions with context no generic chatbot could have.
