Domain Spoofability Scanner

Find out in seconds whether attackers can impersonate your domain in email. We check SPF, DMARC, and DKIM and give you a 0–100 risk score with plain-English fix suggestions.

QR Code Toolkit

Generate QR codes, and scan suspicious ones to reveal where they really go before you tap. Install it to your phone’s home screen for quick scan-and-check on the go.

Link Inspector

Paste a suspicious link and see where it really goes. We peel off Safe Links, Proofpoint, Barracuda and other wrappers to reveal the true destination, then flag look-alike domains, IP-address hosts, and credential traps.

📧
Email Header Analyzer

Paste a suspicious email’s raw headers for a plain-English verdict. We check SPF, DKIM, and DMARC alignment (did anything pass for the sender’s own domain?), the delivery path, and impersonation tricks like a name that hides a different address.

🔎
Image Metadata Inspector

Drop in a photo or screenshot to see what it quietly reveals — the camera or software that made it, GPS coordinates of where it was taken, editing history, and any AI-generation or Content-Credentials markers. Download a metadata-free copy before you share.

Screenshot Redactor

Black out student names, faces, or IDs before you share a screenshot. Unlike a box drawn in Preview or Word, the blacked-out pixels are permanently destroyed in the download — not just covered — and all hidden metadata (including GPS) is stripped.

🔑
Class Password Card Generator

Paste your class roster and get a printable cut-out card for each student with a memorable, strong passphrase (like tiny-frog-cloud19). Words are drawn from a kid-safe list using your device’s secure random generator. Perfect for first-login day.

SPF Analyzer & Builder

Check whether your domain’s SPF record actually protects you — and if it’s over the hidden “10 DNS lookup” limit that silently breaks it. Then build one clean, correctly-ordered record from a checklist of the senders you use, so you never hand-edit an SPF string again.

DMARC Record Builder

Build a correct DMARC record with safe defaults and a step-by-step ramp (monitor → quarantine → reject) so you finally see who sends as your domain — without accidentally blocking your own mail. Look up your current record and get plain-English fixes.
