url2llm 0.2.0

The easiest way to crawl a website and produce LLM ready markdown files

url2llm

I needed a super simple tool to crawl a website (or the links in a llms.txt) into a formatted markdown file (without headers, navigation etc.) to add to Claude or ChatGPT project documents.

I haven't found an easy solution, there is some web based tool with a few free credits, but if you are already paying for some LLM with an api, why pay also someone else?

Quickstart

With uv (recommended):

Thanks to uv, you can easily run it from anywhere without installing anything:

uv run \
   --with url2llm \
   url2llm \
   --depth 1 \
   --url "https://modelcontextprotocol.io/llms.txt" \
   --instruction "I need documents related to developing MCP (model context protocol) servers" \
   --provider "gemini/gemini-2.5-flash-preview-04-17" \
   --api_key ${GEMINI_API_KEY} \
   --output-dir ~/Desktop/

Then drag ~/Desktop/model-context-protocol-documentation.md into ChatGPT/Claude!

With pip (alternative):

pip install url2llm

What it does

The script uses Crawl4AI:

1. For each url in the crawling, the script produces a markdown
2. Then it asks the LLM to extract from each page only the content relevant to the given instruction.
3. Merge all pages into one and save the merged file.

Command args and hints

• To use another LLM provider, just change --provider to eg. openai/gpt-4o
  • always set --api-key, it is not always inferred correctly fron env vars
• Provide a clear goal to --instruction. This will guide the LLM to filter out irrelevant pages.
• Recommended depth (default = 2):
  • 2 or 1 for normal website
  • 1 for llms.txt
• If you need the single pages, use --keep_pages true
• You can specify the concurrency with --concurrency (default = 16)
• The scripts deletes files shorter than --min_chars (Default = 1000)

[!CAUTION] If you need to do more complex stuff use Crawl4AI directly and build it yourself: https://docs.crawl4ai.com/
