That is because raw HTML wastes 80-90% of your context window on nav bars, ads, scripts, and layout noise.</p> <h2> The Problem </h2> <p>A typical 1,500-word blog post lives inside 50-80KB of HTML. The actual content? Maybe 6-8KB. You are paying for tokens that add zero value.</p> <p>I tested 3 real pages:</p> <ul> <li>News article: 14,800 tokens raw HTML vs 2,100 clean Markdown (86% waste)</li> <li>React docs: 22,400 vs 5,800 tokens (74% waste)</li> <li>Reddit thread: 38,600 vs 6,200 tokens (84% waste)</li> </ul> <h2> Why Markdown? </h2> <p>Markdown wins because:</p> <ul> <li>Structure without noise — headings, lists, code blocks survive</li> <li>LLMs are trained on it — every GitHub repo uses Markdown</li> <li>Token efficient</li> </ul> <h2> My Workflow </h2> <p>I built <a href="https://web2md.org" rel="noopener noreferrer">Web2MD</a> to solve this. It is a Chrome extension that converts any webpage to clean Markdown with one click. The conversion engine uses 130+ CSS selectors to strip boilerplate and has dedicated extractors for 14 platforms (YouTube subtitles, Reddit threads, GitHub READMEs, arXiv papers, etc.).</p> <p>All processing happens locally in your browser — nothing is uploaded.</p> <h2> The Math </h2> <p>At GPT-4o pricing ($2.50/1M input tokens), processing 30 pages/day:</p> <ul> <li>Raw HTML: $1.50/day</li> <li>Clean Markdown: $0.30/day</li> <li>Savings: $36/month</li> </ul> <p><a href="https://web2md.org" rel="noopener noreferrer">Web2MD</a> is free (3 conversions/day). Pro is $9/month for unlimited.</p> <p>What is your current workflow for feeding web content to LLMs?</p> ai llm productivity webscraping
