AI-Powered Search

What is AI Search?

AI Search uses Retrieval-Augmented Generation (RAG) to provide intelligent answers to your visitors' questions. Instead of just showing links, FlowSearch can generate a helpful summary based on your actual content.

How It Works

1. Query Understanding — AI analyzes the user's question to understand intent
2. Content Retrieval — FlowSearch finds the most relevant pages from your site and, on Business+, the most relevant uploaded-document chunks
3. Answer Generation — AI synthesizes an answer using crawled content, and Business+ uploaded document excerpts when available
4. Source Citation — Every answer lists its source pages, Business+ documents, and General AI knowledge when External Knowledge is enabled

Enabling AI Search

To enable AI-powered summaries for your site:

1. Go to your website integration page in the dashboard
2. Add the Results Page Script with data-summary="true"
3. Upgrade to a paid plan to enable follow-up conversations and External Knowledge
4. Upgrade to Business or Enterprise to add uploaded document knowledge

The Results Page Script looks like this:

<script
  src="https://www.flowsearch.io/results.js"
  data-key="YOUR_SEARCH_KEY"
  data-summary="true">
</script>

Document Upload (Business+)

Business and Enterprise plan users can upload additional documents to expand the AI's knowledge base:

Uploaded documents are processed for text, split into searchable chunks, embedded for semantic matching, and ranked alongside your website content when the AI answers questions. The first AI Summary after older documents are upgraded may take a little longer while FlowSearch prepares those chunks. Basic and Pro plans do not use uploaded document knowledge.

Uploading Documents

1. Go to your website settings
2. Click the "Documents" tab
3. Drag and drop files or click to upload
4. Wait for processing to complete

AI Summary Placement

Add this Results Page HTML inside the Search Results page with a Webflow Embed/custom code element, or build the same block natively and add the listed attributes.

<div data-fs-summary class="ai-summary">
  <div data-fs-summary-text></div>
</div>

<div data-fs-results>
  <a data-fs-result data-fs-url href="#">
    <h3 data-fs-title></h3>
    <p data-fs-snippet></p>
  </a>
</div>

Best Practices

Content Quality

AI answers are only as good as your content. Ensure:

• Pages have clear, descriptive titles
• Content is well-structured with headings
• Key information is explicitly stated (not just implied)
• Frequently asked questions are answered on your site

When to Use AI Search

Usage Limits

Initial summaries are available on all plans. Follow-up conversations and External Knowledge require a paid plan. When External Knowledge is enabled, General AI knowledge is shown as a source alongside website sources. Uploaded document knowledge requires Business or Enterprise.

Standard searches (without AI summary) do not count against the AI limit.
