Free fact-of-the-day widget

Drop this one-line embed into any website — blog, sidebar, footer, newsletter template — and it renders a verified DeepInquiry fact. No signup, no API key, no rate limits for reasonable use. Every widget links back to the fact's source page for citations — that's how we fund the free tier.

Standard embed

<script async src="https://widget.deepinquiry.ai/embed.js"></script>
<div id="deepinquiry-fact"></div>

Live preview

Options

Add data attributes to the container to customize:

Dark theme

<script async src="https://widget.deepinquiry.ai/embed.js"></script>
<div id="deepinquiry-fact" data-theme="dark"></div>

Set data-theme="light", "dark", or "auto" (default — respects prefers-color-scheme).

Compact layout

<script async src="https://widget.deepinquiry.ai/embed.js"></script>
<div id="deepinquiry-fact" data-compact="true"></div>

Single-line, smaller padding. Fits sidebars and footers.

How it works

• The script fetches one verified fact from api.deepinquiry.ai/api/widget — a public, CORS-enabled endpoint cached at the edge for 1 hour.
• Browsers also cache the result in localStorage for 6 hours, so return visitors don't hit the API repeatedly.
• Every fact goes through model extraction + web-search verification + confidence scoring before it's served. Only status='approved' facts appear.
• The footer link is required by the free tier — it's what pays for the pipeline.
