URLs rarely arrive as a tidy list. They are buried in email threads, pasted chat logs, HTML source, or documents where someone mentioned a dozen links in passing. Extraction pulls them out into a list you can act on.
What it scans for
The tool reads the whole block and returns every URL it finds, discarding the surrounding prose entirely.
Where the input usually comes from
A brief listing competitor pages, an outreach thread with links scattered through the replies, an exported page source, or a document where the links matter and the commentary does not.
What to do with the output
Deduplicate first — the same link is usually mentioned several times. Then extract domains if the question is about sites rather than pages.
