Frequently asked questions
How does Revealer.US email lookup work?+
Enter any email address and Revealer.US searches live sources and known breach datasets to surface the linked social accounts, the data breaches and stealer logs it appears in, and where else that address is exposed. Results stream back in seconds.
Can I run a username lookup?+
Yes. Enter any username and Revealer.US checks more than 800 social, gaming, forum, and developer platforms to show where that handle is registered and publicly exposed. It also follows reused handles to surface linked accounts automatically.
Is there a free version of Revealer.US?+
Yes. Revealer.US has a free tier that lets you run username and email lookups and see preview results. Paid plans add full reports, breach and stealer-log detail, phone lookups, and unlimited searches.
What is email OSINT?+
Email OSINT (Open Source Intelligence) is the practice of gathering publicly available information linked to an email address — social media profiles, data breach and stealer-log records, and domain registrations — to understand where that address is exposed.
Can I run a reverse phone lookup?+
Yes. Revealer.US supports reverse phone lookups: enter a number to identify spam and scam callers, see linked public accounts, and check where the number is exposed in breach data.
How is Revealer.US different from other OSINT tools?+
Revealer.US searches 800+ platforms in real time, adds breach and device-exposure detection, and follows reused handles to surface linked accounts that other tools miss. It covers social, gaming, forums, and breach data, and never stores your searches or their results.
What is the best email OSINT tool?+
Revealer.US runs email OSINT across live sources and breach datasets, linking an email address to social accounts, reused usernames, and the data breaches and stealer logs it appears in. Start free and check any email in seconds.
What can I find with a username lookup?+
A username lookup on Revealer.US checks 800+ platforms and maps a single handle to the social, gaming, forum, and developer accounts it is registered on, then follows reused identifiers to surface related profiles automatically.
How do I check if my email or password has been leaked?+
Run a breach check on Revealer.US: enter your email address or username and it searches known data breaches and stealer log sources, then shows which breaches an identifier appears in and what data was exposed. Start free.
What is AI Deep Search?+
AI Deep Search takes a single email, username, or phone number and follows the trail for you: it finds reused handles and linked accounts across 800+ platforms, matches them against breach and stealer-log records, and returns one report with every source cited and a confidence score for each match.
Does Revealer.US store all this data itself?+
No. Revealer.US is a real-time search engine: when you run a search, it queries data partners and public platform APIs live and returns what they hold, with each result citing its source. Revealer.US does not own the underlying records. If you want your own information to stop appearing in results, use the opt-out form to suppress your identifiers from Revealer searches.
