LLM Override vs Really Simple Security – Simple and Performant Security (formerly Really Simple SSL)

The AI era has a problem: ChatGPT, Claude, and Perplexity are making up facts about your brand. They crawl your raw HTML — a format built for humans — and hallucinate the gaps. Traditional SEO cannot fix this. A static sitemap cannot fix this. LLM Override fixes this. LLM Override is a Machine-to-Machine (M2M) interception engine for WordPress. It speaks the language AI crawlers actually understand: clean, structured Markdown with semantic context — served in real time, directly from your site, without modifying a single page. How AI systems read your content Most AI tools for WordPress generate a list of URLs. That tells an AI crawler where your content is. LLM Override tells AI crawlers what your content means — making your brand accurately represented across AI-powered search engines. When a bot visits your page, LLM Override intercepts the request before WordPress renders any HTML, and responds with a structured Markdown payload containing: Your content, cleaned of scripts, ads, and UI noise A YAML frontmatter block with your canonical title, URL, and last-updated timestamp Your Site Manifest — verifiable organization facts included in your /llms.txt This is Generative Engine Optimization (GEO): making your content accessible and accurately represented to AI systems. How it works LLM Override adds a tag into your page . An AI crawler discovers this link and follows it — that’s the standard Content Negotiation protocol. It appends ?view=raw to your URL and sends the request. LLM Override intercepts at the WordPress routing layer — no HTML is rendered, no theme loads. The crawler receives clean, semantic Markdown. Accurate content. No hallucinations. Your human visitors never see any of this. Their experience is unchanged.

Every function prefixed, every output escaped, every database query prepared, every nonce verified. No direct filesystem operations. No raw SQL injection. No short PHP tags. The plugin passes the official WordPress Plugin Check tool with zero errors and zero warnings. LLM Override Pro — Industrial-scale GEO The free version covers the complete core M2M engine.
