The Companion Suite

These companion plugins solve critical developer challenges when preparing WordPress sites for AI crawlers, retrieval engines, and LLM consumption.

AgentMark

AI-Ready Markdown Endpoints & llms.txt Discovery for WordPress

WordPress outputs heavy HTML that AI crawlers struggle to parse accurately. AgentMark solves this by generating an industry-standard /llms.txt discovery manifest and lightweight .md endpoints for every post and page.

Key Capabilities
  • /llms.txt & /llms-full.txt: Automatically advertises your key content to Perplexity, Claude, ChatGPT, and AI agents.
  • Instant .md Endpoints: Append .md to any WordPress URL to retrieve cleanly parsed Markdown.
  • YAML Front Matter: Embeds rich machine-readable metadata (author, date, tags, categories) for accurate AI reasoning.
  • Zero Configuration: Built-in rate limiting, caching, and per-post privacy controls with zero setup needed.
Terminal Discovery Example HTTP 200 OK
$ curl -s https://yoursite.com/llms.txt

Content Negotiation Official WP Plugin

Markdown for AI Agents

Serve Clean Markdown Versions of WordPress Content via HTTP Headers

Enables HTTP content negotiation for WordPress. When an AI crawler or RAG pipeline sends an "Accept: text/markdown" header, it receives pure Markdown without page boilerplate, reducing token costs by up to 60%.

Key Capabilities
  • HTTP Content Negotiation: Intercepts Accept: text/markdown requests seamlessly at the HTTP protocol layer.
  • Up to 60% Token Reduction: Strips navbars, headers, footers, scripts, and theme widgets before ingestion.
  • Zero Visible Impact on Humans: Regular visitors browsing with standard browsers always receive normal HTML.
  • Rich HTTP Metadata: Adds Vary: Accept, Content-Type: text/markdown, and X-Markdown-Word-Count headers.
Terminal Ingestion Example Content-Type: text/markdown
$ curl -H "Accept: text/markdown" https://yoursite.com/post/
# Post Title (Markdown)

How our plugins power the full AI and search lifecycle

When used together, our plugins form a unified pipeline that optimizes your WordPress content from internal link structuring through external AI discovery and lightweight model ingestion.

1

Structure Internal Links

LinkCortex analyzes keyword density and semantic relationships in your WordPress database to build coherent topic clusters and eliminate orphan pages.

2

Advertise via llms.txt

AgentMark broadcasts your structured topic clusters to LLM crawlers via standard /llms.txt files and exposes dedicated .md endpoints for each article.

3

Serve Token-Light Markdown

Markdown for AI Agents intercepts HTTP Accept: text/markdown requests to serve clean, boilerplate-free Markdown directly into RAG ingestion pipelines.

Our Core Engineering Standards

Every tool we release adheres to strict software engineering rules designed to keep production WordPress environments stable and performant.

Zero Data Exfiltration

Your content, database, and visitor requests remain strictly on your server. We never run external data brokers or telemetry hubs.

Clean Core API Usage

We build on modern WordPress core APIs like WP_HTML_Tag_Processor and template_redirect instead of volatile regex string replacements.

Lightning Execution

Lightweight footprint with zero background cron CPU spikes, fast local memory execution, and zero third-party tracking scripts.
