What is Retrieval-Augmented Generation (RAG)?
Also known as Retrieval-Augmented Generation (RAG).
Retrieval-Augmented Generation (RAG) is how an AI answers using sources it was never trained on: it splits documents into chunks, finds the chunks that match the question, and hands only those fragments to the model. It is why your page is read as pieces rather than as a whole.
- Documents are split before they are stored, typically by heading section and then into token windows of a few hundred tokens with a small overlap.
- The model sees one chunk at a time, without your heading hierarchy, your introduction or the paragraph above it. A sentence starting 'It also supports…' becomes meaningless.
- This is why self-contained writing matters more for AI than for humans. Naming the subject again instead of writing 'it', and deleting phrases like 'as mentioned above', directly changes whether a fragment is usable.
- Sections longer than the chunk window get split, and only the first piece keeps its heading. Shorter sections are therefore safer.

Retrieval Chunk Preview
See your page the way a RAG system does: split into retrieval chunks and read one at a time, with no surrounding context. Flags every fragment that collapses alone: pronoun openers, 'as mentioned above', sections that never name their subject.
Content Citability Scorer
Score any page or draft on the factors a published study (KDD 2024) measured as increasing AI citation: fact density, source citations, quotability, answer-first openings, question headings and self-containment. Every sub-score shows its formula and what it counted.
Answer Snippet Checker
Check whether every section of your page opens with a self-contained answer in 40 words or fewer. Flags throat-clearing intros, buried answers and openings that depend on missing context, with a rewrite target for each failure.

- Generative Engine Optimization (GEO)Generative Engine Optimization (GEO) is the practice of making a website usable by AI answer engines like ChatGPT, Claude, Perplexity and Google's AI features, so they can crawl it, read it without JavaScript, and quote it as a source. It overlaps with SEO but optimizes for being cited rather than ranked.
- AI crawlerAn AI crawler is an automated bot that fetches web pages on behalf of an AI company, either to train a model, to build a search index that AI answers cite from, or to read a page live when a user asks about it. Each purpose is a separate bot with its own name in robots.txt.
