What you get

One email, the full picture

Most email checkers stop at a yes or no. IntelBase gives you the account, the details on it, the person behind it, and the data that leaked from it.

Registered accounts

Every platform the email is registered on, checked in real time, not looked up in a stale cache.

Profile details

Display names, usernames, profile photos, bios, locations, and linked sites pulled from each account found.

Recovery hints

Partially masked phone numbers and backup emails exposed by account recovery flows, so you can pivot to the next identifier.

Data breaches

Every breach the email appears in, with the source, date, and the fields that leaked alongside it.

Infostealer logs

Credentials captured by stealer malware, including the URL each one was saved for and enrichment from the infected device.

Activity timeline

Account creation and update dates merged into one timeline, so you can see when the email first showed up online.

Likely owner

The name and face that the address's accounts agree on, with an explanation of which details tie them together.

Authenticity & exposure scores

Two 0–100 scores: how established the address looks and how exposed its credentials are, each with the reasons behind it.

Suggested next searches

Usernames and other emails found in the results, ranked by whether they belong to the same person, ready to search next.

Beyond registration checks

Know who's behind the address and what has leaked

Account presence tells you who someone is. Exposure tells you what's at risk. Every email lookup works out both, so investigators and fraud teams get answers without switching tools.

The likely owner

Names, profile photos, bios, and links from every account are compared to find the person they describe, shown with their name and photo at the top of the report.

Accounts that don't fit

An account showing someone else's name is flagged. That can mean the address was mistyped at sign-up, recycled, or is shared, which matters before you act on it.

Breach history

See which breaches the address was part of and which fields came with it: passwords, hashes, IPs, phone numbers, and names.

Stealer log exposure

Find out if the email was harvested from an infected machine, which login URLs it was saved for, and when the log was posted.

Workflow

How it works

From a single email address to a full report, in one search.

  • Enter an email address

    Paste a single address in the dashboard, upload a list with bulk lookup, or send it to the API.

  • Platforms are checked live

    Every platform is queried in parallel and results stream into your report as each one responds.

  • Exposure and ownership are checked

    The address is checked against breach data and infostealer logs, and the profiles found are compared to see whether they all fit one person.

  • Review, pivot, and share

    Follow usernames and phone hints into new lookups, map connections in the graph, and publish the result as a shareable report.

API

Build it into your stack

Run the same lookup from your own systems. Get every account, the likely owner, breaches, and stealer logs as structured JSON, or stream results as they arrive.
