How Text-to-Domain Extraction Works 🚀 Extract now

The tool tokenises the input by regex, matching every string that looks like a hostname — with or without http(s)://, with or without www.. Each candidate is validated against the current IANA TLD list. Emails are detected separately and their domain part is extracted. Finally, results are deduplicated case-insensitively.

FAQ 🚀 Extract now

Can I extract a domain from a single string like "[email protected]"?
Yes. Paste the string, keep Source Type = Plain text (mixed), and click Extract. You'll get example.com.
How do I extract a domain from a URL inside text?
The default text mode already does this. If your input is 100% URLs, one per line, switch to URL list only or use the URL Domain Extractor for cleaner defaults.
Will it pick up bare hostnames like "api.stripe.com" without a scheme?
Yes, as long as the TLD is recognised. The regex works with or without http://.
Are false-positives (like "3.14" or "file.txt") filtered?
Yes. Every candidate must have a valid IANA TLD, so file.txt, 3.14, version.2, etc. are rejected.
