Questions & Answers

As answered by people managing JavaScript Operator Lookup and ScanTheSender.

What makes your product unique?

ScanTheSender's answer:

ScanTheSender is completely free with no signup required and no daily scan limits — unlike most competitors that restrict free users to a handful of checks per day. It also accepts screenshots as well as pasted text, so users can check WhatsApp messages, texts, and emails all in one place.

Why should a person choose your product over its competitors?

ScanTheSender's answer:

Most scam checkers either charge for unlimited use or cap free users at 2-3 checks per day. ScanTheSender is fully free with no limits, no account creation, and results in seconds. It also provides a detailed breakdown of exactly why an email is flagged as suspicious — not just a simple yes/no verdict — helping users learn to spot scams themselves in future.

How would you describe the primary audience of your product?

ScanTheSender's answer:

Everyday internet users who receive suspicious emails, texts, or messages and want a fast, reliable second opinion before clicking a link or sharing personal information. This includes people of all ages and technical backgrounds, particularly those less confident identifying phishing attempts on their own.

What's the story behind your product?

ScanTheSender's answer:

ScanTheSender was built after noticing how convincing modern phishing emails have become — even experienced internet users can be fooled by well-crafted fakes impersonating major brands like Amazon, PayPal, and Microsoft. The goal was to create a completely free tool that gives anyone instant clarity on a suspicious message, without paywalls or signup friction getting in the way of genuine help.

Which are the primary technologies used for building your product?

ScanTheSender's answer:

WordPress, OpenAI for AI analysis, custom PHP, and JavaScript for the frontend scanner interface.

Who are some of the biggest customers of your product?

ScanTheSender's answer:

Individual consumers checking suspicious emails and messages
