Your car. Your gate. Your bike. A package on the porch, a tool on the job site. TextTags puts a Tag on the things you care about — a QR code that lets anyone nearby give you a heads-up the moment something needs your attention. Design your Tag in the app, download and print it for free, or order it as a sticker, magnet, pin, or luggage tag. Then stick it wherever life happens. When someone scans your Tag, they can notify you straight from their phone's camera — no app to install, no account to create, no chat service to join. You get a notification instantly and reply right from TextTags. No phone numbers, no emails, nothing exchanged but the message itself. And one Tag handles it all: every person who scans it gets their own separate thread with you. WHAT PEOPLE TAG • Cars & trucks — your lights are on, you're blocked in, the alarm's going off, a tire looks flat • Bikes & scooters — the lock's broken, it tipped over, it's been sitting there a while • Keys, wallets & bags — the moment they turn up, the finder can tell you • Pets — someone spots your dog before you even knew they were gone • Packages & mail — a delivery is sitting at the door, unattended • Tools & equipment — left behind on site, damaged, or in the way • Property & access — the gate's open, the driveway's blocked, something needs service • For-sale signs — questions and offers, without your number living in a stranger's phone forever BUILT-IN SAFETY • Every message, intro, display name, and piece of uploaded artwork passes through an AI safety filter before it's delivered or printed — abusive or inappropriate content never reaches you • Only someone who scans your specific physical Tag can notify you — there's no directory, no browsing, no matching with strangers • A scan is a heads-up, not an open line — you decide whether a conversation is worth having • Block or report any conversation with a tap — or pause or delete the entire Tag • Set the safety filter and reply rules per Tag — you're in control of every Tag you create DESIGN IT, ORDER IT, DONE Every Tag starts as a QR code you can download and print for free. Want something sturdier? Design real merchandise around it right in the app — stickers, magnets, pins, and luggage tags — previewed exactly as they'll print. Check out securely with Apple Pay or card, and it ships straight to your door. Your first Tag is free. Need more? Grab a pack. Every thing has a person behind it. Message them.
