Same person,
different accounts?

Paste a batch of email addresses. The engine resolves which ones belong to the same person, flags fake or throwaway addresses, and tells you exactly why for every match it proposes.

Heads up: this demo is a work in progress. I'm still actively building it, so expect rough edges and the occasional odd result.

• Deterministic first

  Dots, +tags, and alias domains collapse to one canonical mailbox. Exact matches outrank everything below.

• Structural variants

  Incrementors (name1, name2), reordered name parts, leet spellings, and one-keystroke typos of the same base.

• Name linkage

  Fuzzy matching keyed on the surname. A shared first name alone never links two people.

• Risk flags

  Disposable and relay domains, homoglyph tricks, machine-generated locals, catch-all patterns.

Decisions run server-side at/api/matchthe page never decides
