Fernando Tellado

AI Content Signals lets you declare, in a machine-readable way, how AI systems may use your content: for search indexing, real-time AI answers (RAG), or model training. It started with Cloudflare’s Content Signals in robots.txt and now expresses the same preferences across several surfaces, so more crawlers and tools can read them:
<ul>
<li>robots.txt — Cloudflare Content Signals (search / ai-input / ai-train)</li>
<li>HTTP header — <code>X-Robots-Tag: noai, noimageai</code></li>
<li>HTML meta — robots <code>noai, noimageai</code></li>
<li>/.well-known/tdmrep.json — W3C Text and Data Mining Reservation Protocol</li>
<li>EU Directive 2019/790 rights reservation</li>
</ul>
Everything is opt-in and does not change your robots.txt output unless you enable it.
The signals you control
You set three preferences, and AI Content Signals expresses each one in the right format on every surface you enable:
<ul>
<li>search — allow or deny search indexing and traditional search results (links and short snippets)</li>
<li>ai-input — allow or deny using your content for real-time AI answers (RAG, grounding, AI Overviews)</li>
<li>ai-train — allow or deny using your content to train or fine-tune AI models</li>
</ul>
These three come from Cloudflare’s Content Signals vocabulary, written to your robots.txt. When you deny AI training, the same opt-out is also emitted on any other surface you enable: <code>noai, noimageai</code> in an HTML meta tag and an <code>X-Robots-Tag</code> header, plus a <code>tdm-reservation</code> in your TDMRep manifest. Declaring the same preference in several places means a crawler that ignores one signal may still honor another.

Important Notice
Content Signals is a declarative standard – it expresses your preferences but does not technically enforce them. AI companies are not legally required to respect these signals, though the plugin includes legal text referencing EU copyright directives.
The IETF AI Preferences (AIPREF) Working Group is currently developing a formal standard based on similar concepts. This plugin implements the current Cloudflare Content Signals specification and will be updated as standards evolve.
This plugin works best when combined with other protection measures like traditional robots.txt rules and server-level bot management.
