HTML to LLM Markdown →
Convert complex HTML into clean, token-efficient Markdown for LLM prompt context, RAG embeddings, and documentation mirrors.
How It Works
Uses BFS recursion to crawl same-origin internal links, extracts mailto protocols and RFC 5322 text nodes, and classifies emails into corporate departments using DOM card context and heading heuristics.
Formula & Technical Methodology
Deterministic RFC 5322 regex + Cheerio DOM hierarchy tree analysis without language model calls.
When Should You Use This Tool?
When conducting ethical contact discovery, building vendor lists, or identifying company departments without expensive third-party scraping APIs.
Practical Example
Enter company.com: the tool crawls 25 internal pages and returns 18 verified emails cleanly mapped to Sales, HR, Executive, and Support with 1-click CSV export.
Frequently Asked Questions
- Does this tool use AI or large language models?
- No. It runs entirely on deterministic RFC 5322 regular expressions, HTML DOM tree traversal, and heuristic prefix dictionaries.
- Can I export the extracted contacts?
- Yes. You can copy the emails as comma-separated or newline lists, or download them as structured CSV or JSON files.
