Paste anything
Threads, exports, notes or a copied web page. Domains are found mid-sentence, inside URLs and after an @ — duplicates included.
Domain Cleaner
Paste messy text. Get a clean list.
Paste anything, then clean & copy
Email threads, CSV exports, old spreadsheets, a page of notes — this pulls every domain out of the pile, drops the duplicates and the free mail providers, and copies the result. It all happens in your browser; the text is never sent anywhere.
- Nothing uploaded
- No account needed
- Copied as you go
How it works
Three steps, and none of them leave this page.
Set the rules
Upper or lower case, sort A–Z or by extension, and switches for duplicates, free mail providers and subdomains.
Clean and copy
One press replaces the paste with your sorted list and puts it on the clipboard, ready for the bulk domain search.
Before you start
The questions people ask about the Domain Cleaner.
Short answers — the tool itself is simpler than it looks.
Does my text get sent anywhere?
No. The cleaning runs entirely inside your browser — there is no upload, no server and no copy of your list on our side. You can disconnect from the internet after the page loads and it will still work.
What counts as a free mail provider?
The common consumer mail services — hotmail.com, gmail.com, outlook.com, yahoo.com and similar — plus a few registry addresses that are never a business's own domain. Turn the option off if you want them kept.
How many domains can it handle?
A few thousand in one pass without any trouble. If you have more than about 400 KB of text, split it into batches — the tool will tell you rather than freeze.
What do I do with the list afterwards?
Take the copied list straight to the bulk domain search, where you can check hundreds of names for availability in one go — or paste it wherever you work.

The bulk search checks the whole batch at once, with the price for each one shown before you add anything to the cart.
