No signup · Fictional emails · About two minutes

01

Pick a fictional email

Thirteen examples, from routine invoices to a changed payment request.

02

Inspect the evidence

Check sender details, reply addresses, links, and supplied authentication signals.

03

Choose a next step

Use a previously trusted channel to verify sensitive or unusual requests.

Built around the latest Mailcheck rules.

Explore lookalike letters, invisible characters, unusual spacing, and ordinary typos alongside sender and payment warning signs. Compare what saved-email and visible Gmail text can reveal.

The local app now has a Chrome/Gmail extension prototype and a saved-email upload flow in progress. This visitor demo illustrates their coverage with fictional messages. No upload, paste box, inbox connection, or extension download is offered here.

A prototype with clear limits.

Deterministic rules highlight warning signs; they can miss fraud and flag legitimate messages. This demo has not been validated on real inboxes. “No clear warning signs” is never a guarantee of safety.

Everything runs in browser memory. No email import, external scanning, or mailbox actions. Reset or reload to start over.

A SECOND LOOK, WHEN YOU NEED IT

A little clarity.
A more confident next step.

Check the details before you reply, click, or pay.

START WITH WHAT YOU KNOW

Fictional verified vendor

See how independently verified details inform a check.

A familiar name is not proof of identity. In a real workflow, verify vendor details independently before trusting them. Here, one fictional entry is preloaded. Changes stay in memory until you reload or reset.

Explore the comparison

Northline Supply is fictional. Remove its demo entry to see how results change without known vendor details, then restore it. This showcase accepts no vendor or email input.

CLEAR REASONS. YOU DECIDE.

A second layer of awareness

A quiet check before an important action.

01

Choose an example

Explore routine messages, vendor impersonation, payment changes, and incomplete information.

02

Check the details

Rules compare sender domains, reply addresses, supplied links, authentication metadata, payment language, invisible characters, mixed-script names, unusual spacing, and a small list of possible English typos.

03

Verify independently

For payment changes, use a phone number or address you already verified. A genuine account can be compromised too.

The app and this showcase

The local app includes a user-triggered Chrome/Gmail extension prototype. It reads an expanded message’s visible content only; it does not verify authentication headers, inspect attachments, or scan an inbox. Live Gmail compatibility still needs self-testing. A saved .eml intake flow and a secondary manual-entry fallback are in progress in the local app.

This showcase uses the same deterministic rule engine and thirteen fictional examples. Its saved-email and Gmail modes simulate coverage only: no MIME parser, real email upload, manual entry, extension installation, or Gmail access is included.

What this demo can and cannot do

No inbox, AI service, analytics, or external reputation service is connected. Messages and vendor changes remain in browser memory. Reload or reset to clear them.

Links are displayed as text. Attachments, websites, redirects, and images are not inspected. Authentication results in the examples are synthetic. Passing authentication does not prove that a request is legitimate.

The rules are a starting point. They can miss fraud, and legitimate messages can trigger warnings. The demo has not been evaluated on real inboxes.
