HTML to markdown API that renders the page first

A naive HTML to markdown converter chokes on modern sites, because the content is not in the HTML until JavaScript runs. ClawEngine is an HTML to markdown API that renders the page in a real browser environment first, then converts the resulting DOM into clean markdown with the boilerplate stripped out.

Give it a public URL and you get back tidy markdown that preserves headings, lists, tables and links, ready to embed or index. There is no browser or converter to run on your side. ClawEngine processes public, permitted pages only, respects robots.txt and site Terms of Service, and honors crawl-delay, so the conversion is both clean and compliant.

Why it works

What you get with html to markdown

Renders, then converts

JavaScript runs before conversion, so content that only exists in the rendered DOM makes it into the markdown, unlike a static HTML parser.

Clean, faithful markdown

Headings, lists, tables and links are preserved while ads, navigation and scripts are dropped, so the markdown mirrors the real content.

No browser to run

The rendering and conversion happen in the API, so you skip running and scaling a headless browser just to get markdown.

What it handles

Any URL in, clean structured data out

Point ClawEngine at a public page and it crawls, renders the JavaScript and extracts clean markdown or typed JSON in one call. Define a schema for structured fields, and respect robots.txt and Terms of Service by default.

Why ClawEngine

One API that crawls, renders and extracts

Not a raw HTML dump, not a headless browser fleet to run, and not a brittle parser to maintain. One call crawls a public page, renders its JavaScript and returns clean markdown or typed JSON, built for RAG pipelines and AI agents.

LLM-ready output

Clean markdown or typed JSON with the boilerplate stripped, so the data drops straight into a vector store, a prompt or an agent without a cleanup step.

JavaScript rendered

Each page loads in a real browser environment before extraction, so single-page apps and client-rendered content come back complete, not as an empty shell.

Compliance-first

ClawEngine works on public, permitted data only. It respects robots.txt and site Terms of Service and honors crawl-delay, so responsible scraping is the default.

Good questions

Questions about html to markdown

A local library converts whatever HTML you already have, which on modern sites is often an empty shell before JavaScript runs. ClawEngine renders the page first, then converts, so the markdown reflects the fully loaded content.

You give ClawEngine a public URL and it fetches, renders and converts the page for you. It targets public, permitted pages only and respects robots.txt and Terms of Service.
