Intelligence X alternative: Seer compared

Both tools let you look up an email or domain and see where it appears in leaked data. Intelligence X is an archive and search engine over many source types, including raw documents, paste sites and darknet pages, searched by technical selectors. Seer is four structured surfaces - breached credentials, device records, social accounts and US people search - with a live social resolver; neither covers everything the other does.

Checked against the Intelligence X pages under Sources on October 6, 2026.

What Intelligence X is

Intelligence X describes itself as a search engine and data archive. It searches Tor, I2P, data leaks, paste sites, Whois data and the public web by selectors such as email, domain, IP, CIDR and Bitcoin address, and keeps historical copies of pages and documents that can be viewed inline.
