Messagent

Tired of gambling and scam texts? Keyword blockers don't work. Spammers write "c@sino", "c a s i n o", "b3t" and slip right through. Messagent works differently: it looks at what a message means, not just what it says. Messagent is an AI-powered SMS protection app. It recognizes gambling, scam, advertising and unsolicited loan texts by their meaning and filters them silently before you ever see them. MEANING, NOT KEYWORDS Classic filters look for the word "casino"; a spammer swaps one character and walks through. Messagent uses AI to understand a message's topic; it's caught no matter how it's disguised. WRITE YOUR OWN RULE "No political party texts", describe what bothers you in your own words. Messagent resolves it into topics and blocks every message about it. No keyword lists to manage. ADVISOR: "IS THIS MESSAGE SAFE?" Got a suspicious message? SMS, WhatsApp or email, paste it in or pick a screenshot. Advisor tells you the risk, the red flags and exactly what to do, in plain language. It safely unshortens links (like bit.ly) and shows the real destination, before you tap. Set it up for your parents. COMMUNITY RADAR When one user flags a spam sender, it's blocked automatically on everyone's device within hours. The shield grows with the community. PRIVACY COMES FIRST Filtering happens on your device first. Your bank verification codes (OTP) never leave your phone. Undecided messages are processed only for an instant classification and are never stored. No content, no identity. FEATURES โข AI meaning-based classification (not keyword lists) โข Write your own rules in natural language โข Advisor: suspicious-message analysis + link safety check โข Community Radar: anonymous, auto-spreading protection โข Weekly protection report โข Category-based customization (gambling, ads, loans, scams) โข Light and dark themes โข OTPs never go to the cloud HOW IT WORKS Uses Apple's SMS Filtering framework. The filter only applies to senders NOT in your contacts; messages from people you know are never touched. Unwanted messages move to the filtered section of the Messages app; they're never deleted and you can view them anytime. PRICING 7-day free trial, then a monthly or yearly subscription. Cancel anytime from your App Store account. Note: Apple only grants filter apps access to SMS/MMS; iMessage and WhatsApp can't be filtered directly (but you can paste them into the Advisor).
