What HTML Does to Your LLM Context Window (And What to Do About It)
Most LLM pipelines have a data quality problem that nobody talks about at conferences. You’re fetching web content — documentation, knowledge base articles, competitor pages, product data — and feeding it directly into your AI pipeline. The content looks fine in your browser. But what your model actually receives is something else entirely. It’s a context window full of <div class="wrapper"><div class="inner"><div class="content">, navigation menus, cookie banners, JavaScript snippets, tracking pixels, and somewhere in the middle, the three paragraphs of actual content you wanted.
