Scammers only need to get it right once. You have to be right every time. TellSign puts an elite AI security team between your money and them. Paste any suspicious text, link, QR code, screenshot, or voicemail — three independent AI models cross-check it, a judge model breaks ties, and you get a clear verdict with next steps in about 20 seconds. WHY PEOPLE TRUST TELLSIGN Tri-Model Consensus — every check runs through 3 distinct AI models. Zero guesswork. Deep Investigator — when a threat is clever, the engine digs deeper until the picture is clear. Voice Check — got a suspicious voicemail? Play it to TellSign. We transcribe and analyze it. Bait Mode — reply to scammers with AI-crafted decoys that waste their time, not yours. Family Guardian — link your parents' phones and watch over the family from your own. Share from anywhere — check a message straight from the share menu, no copy-paste needed. Slow Burn — quietly watches a conversation over days and warns, with receipts, when it moves like a long con. Daily Immunity — a real scam a day. Keep the streak, learn the tells. Guardian Handshake — one tap between family phones defeats “new number” and voice-clone scams. PRIVATE BY DESIGN No account. No history stored on our servers. Content is analyzed in transit and discarded — we see nothing, log nothing, keep nothing. PLANS The free tier includes starter safety checks. TellSign Premium adds a generous daily allowance, the Deep Investigator, Voice Check, Bait Mode, and Family Guardian for 2 phones. TellSign Pro is built for heavy, real-world use — several times the daily allowance, Family Guardian for up to 4 phones, and a bigger Bait Mode budget. One scam caught pays for a lifetime of protection. Terms: https://tellsign.org/terms · Privacy: https://tellsign.org/privacy

Verdict
The clearest difference is in-app purchases: YYIOT at none against Tellsign's 2. YYIOT also leads on device support (3 vs 1). Tellsign's advantage is update cadence (every 6 days vs every 6 weeks). On price, ads and iOS requirement there is nothing between them.
