Run a paired before/after experiment on any URL. See exactly how HTML structure affects LLM fact extraction — token cost, accuracy, and hallucination rate.
We fetch the page, create a structurally optimised twin, and compare extraction metrics side-by-side. Zero LLM API calls — fully deterministic.

The Golden Semantic String is what an LLM actually reads: Title + Meta + H1 + H2s + first ~600 words of body content + JSON-LD entities. Everything else is noise.
Run a comprehensive crawl with template-level analysis, historical tracking, and automated remediation snippets.
