Before You Send — Naineeth Gandhi

Before You Send is a privacy-first assistant that quietly watches for harmful, threatening, or scam-related content right as you're about to send a message — and warns you before it goes out. It also flags dangerous incoming messages, like phishing links disguised as safe shortened URLs. It runs quietly in the background across the popular messaging, email, and social sites you already use.

What it catches:

63+ harm and scam categories — harassment, threats, blackmail, advance-fee fraud, OTP-harvesting scams, self-harm language, and more
Scam and phishing links, including shorteners hiding an open-redirect
Leetspeak, styled-font, and bidirectional-text tricks people use to sneak flagged words past filters
19 languages, including hybrid and code-switched text (e.g., Hinglish, Hebrew/Yiddish mixes)
Built to respect you, not spam you:

Trust a site (or mute/reduce a specific category) if it's triggering warnings you don't want
See exactly which phrase was flagged, and why
A quick "looks fine" confirmation for safe messages — not naggy, not constant
A toolbar badge and an optional weekly summary notification, so you can see protection is active without opening the popup
