Live lookup badge
A status chip in the chat header checks the open chat's number against the case file: red with a count when reports exist, neutral when none are on file, with a one-click link to the full case file.

The Scammer Case File extension lives inside WhatsApp Web: every chat you open is checked against the community case file, and reporting a scammer takes one click — with the conversation already filled in as evidence.
A status chip in the chat header checks the open chat's number against the case file: red with a count when reports exist, neutral when none are on file, with a one-click link to the full case file.
A floating report button opens a prefilled form — the contact's name, number, and their recent messages already in place. Pick a scam type, complete the human check, submit. The report is live immediately.
No green checkmarks, no "verified safe" claims. The extension repeats the site's rule everywhere: reports are community-submitted warning signs, not verdicts.
It reads the open chat locally in your browser, only to show the lookup badge and to prefill a report you explicitly start. Nothing is sent anywhere until you click Submit — and then only what you see in the form.
Because "no reports yet" is not proof a contact is safe — it only means nobody has filed a report. A green check would be a false safety signal, so the extension deliberately stays neutral.
The automatic lookup needs the phone number, which WhatsApp Web only shows in the header for numbers not in your contacts. For saved contacts, open the report modal and type the number — the rest still prefills.
Yes — free, open source, no account, and it talks to the same public API (the MCP endpoint) any AI agent can use.
File a report with the number, name, and what happened — it's published immediately and warns the next person who searches.
