EchoThread is a lightweight, privacy-first comment system — a modern <a href="https://echothread.io" rel="nofollow ugc">Disqus alternative</a> that doesn’t sell your readers’ data or inject ads. This plugin drops EchoThread into any WordPress theme with no code: enter your site key, choose where comments appear, and you’re live.
It’s a thin wrapper around the hosted EchoThread widget (~37 KB gzipped, loaded async from a CDN). All storage, rendering, moderation, and spam filtering happen in the hosted service, so the plugin adds no tracking, no database tables, and no page-weight beyond the widget script.
<h4>Why EchoThread</h4>
<ul>
<li>Privacy-first — no ad tech, no third-party trackers, no data resale. GDPR-friendly.</li>
<li>AI / ML spam filtering — machine-learning moderation catches AI-generated comment spam that keyword filters miss.</li>
<li>Threaded replies & reactions — a modern discussion UX, not a flat list.</li>
<li>Fast — one async script, zero render-blocking, no jQuery.</li>
<li>Free tier — get started without a credit card.</li>
<li>Disqus migration — import your existing comments via WXR so no conversations are lost.</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Create a free account and a site at <a href="https://echothread.io/register?utm_source=wordpress&utm_medium=plugin&utm_campaign=readme" rel="nofollow ugc">echothread.io</a>.</li>
<li>Install and activate this plugin.</li>
<li>Go to Settings → ThreadBridge Comments for EchoThread, paste your shortname and API key.</li>
<li>Choose placement — Replace the theme comments (recommended), Append below content, or Manual via the <code>[echothread]</code> shortcode.</li>
</ol>
That’s it. Comments render on your posts immediately.
<h4>Privacy</h4>
This plugin loads <code>https://cdn.echothread.io/widget.js</code> on singular posts/pages where comments are enabled. The widget communicates with the EchoThread API to load and post comments. The plugin itself sets no cookies and collects no personal data. See the <a href="https://echothread.io/privacy" rel="nofollow ugc">EchoThread privacy policy</a> for how the hosted service handles comment data.
