VerifyLink Inbox Guard
A consumer app that flags any link claiming to be from your bank, doctor, or utility with a clear 'verified' or 'unsigned' badge before you click.
Everyday internet users worried about phishing texts, emails, and DMs
- Register trusted contacts (your bank, kids' school, doctor) once; app checks every link against signed claims
- Plain-English explanation of who cryptographically signed a link, not just a green padlock
- Auto-warns before clicking a link from an unknown source claiming to be a registered contact
- Family-shared verification list so a relative can protect an elderly parent remotely
AI-generated phishing makes traditional sender verification unreliable, and Certisfy-style signed-URL systems now give consumers a usable trust layer for the first time.
HN post got 16 points but phishing is a universal consumer pain with billions lost annually and rising AI-generated scams.
Mainstream browsers ship no link-signature checking; brand verification exists for email (BIMI) but not for arbitrary URLs.
Consumers tolerate freemium for security ($2-5/mo) but conversion is harder than B2B; brand partnerships could subsidize a free tier.
Impersonation and phishing scams will only increase as generative AI matures; cryptographic verification is a permanent need.
Requires either partnership with Certisfy-like PKIs or building your own and convincing consumer brands to issue signed URLs.
