What this is
Drop a messy spreadsheet, an AI agent dedupes and matches it, explains every merge in plain language, and hands back a clean file. No signup to try.
You have a messy spreadsheet. The same company shows up three times spelled three different ways. The same person is in there twice with a typo in their email. Before every campaign send, board deck, or event you sit down and hand-clean it in Excel, and next cycle the export is dirty again.
This tool fixes that. Drop a CSV, an AI matching engine finds the duplicates, an agent reviews and explains every merge, and you download a clean file. A few seconds, no setup, no signup to try.
The 30-second version
Upload a CSV of contacts, customers, members, attendees, accounts — any list with duplicate rows. Or click Try a sample to run a built-in messy file first.
The engine groups rows it thinks are the same real-world thing, even when the text doesn't match exactly. An AI agent then reviews each group and labels it Confirmed, Uncertain, or Rejected, with a one-line reason you can read.
One survivor row is kept per duplicate group. The cleaned CSV is built right in your browser and downloads to your machine.
Why not just use Excel's "Remove Duplicates"?
Excel's built-in dedupe only catches exact matches. It sees Acme Inc,
Acme, Inc., and ACME as three different companies and leaves all three in your
list. This tool catches the near-duplicates a human would catch — different
casing, punctuation, spacing, nicknames, and typos. That is the whole point. See
Why fuzzy matching wins.
Who it's for
It's for the person who owns the list. RevOps and marketing-ops analysts, data and business analysts, solo or junior CRM admins, membership and event coordinators, data stewards — anyone whose week includes "clean this spreadsheet before I can use it." It's CRM-agnostic and size-agnostic: if you can export a CSV, you can use it.
