Answer-First Design
L3A content structure where each paragraph or section opens with the direct answer to the question posed by the heading, optimised for AI models that extract answers from the first sentences of a text block.
Atomic Content Unit
coreThe practice of structuring information as the smallest possible independent units of meaning, designed to be easily ingested, re-combined, and repurposed by AI agents without losing context. Atomic Content Units enable AI systems to extract single factual claims cleanly rather than inferring from unstructured paragraphs. Increases Citation Rate and reduces hallucination risk.
Chunk Optimization
coreStructuring content into self-contained units of 100–150 words where each section addresses one specific question, making it easy for AI models to extract, understand and cite the information.
