ChkM8 – The Future of Safe Connections NEW UPDATE: ChkM8 has a bold new look and smoother app experience — making it easier than ever to meet confidently, safely, and authentically. In today’s world, most connections start online — but how do you really know who’s behind the screen? That’s where ChkM8 changes the game. ChkM8 is a portable reputation app that helps you make safer, smarter connections. Through anonymous, mutual ratings, users can evaluate one another in three key areas: Integrity – Are they honest and respectful? Likeability – Were they enjoyable to be around? Safety – Did you feel comfortable meeting them? Each rating is private by default, but users can choose to share their composite scores to show who they really are — a simple, credible way to stand out in a crowd of profiles. How It Works Consensual Ratings: Both users agree to rate one another after a meetup. Flexible Options: Use “Rate Now” right after a connection or schedule a rating within 24 hours. Anonymous by Design: No chat, no DMs — just verified behavior. Transparency: You can view how others have rated the people you meet, without ever revealing your own identity. ChkM8 helps you feel secure — not because someone else says they’re trustworthy, but because you’ve seen how they’ve behaved with others. Whether you’re meeting a date, a marketplace contact, or anyone new, ChkM8 turns reputation into real-world safety. Meet confidently. Rate honestly. Live safely.

EchoVault helps you build something your family can turn to after you're gone: an AI Echo trained on your real stories, your real voice, and your own way of seeing the world. This isn't a chatbot performing as you. It's a living record of who you actually were, built while you're still here to shape it yourself. You build your Echo through Check-Ins, simple guided conversations with an AI biographer. You talk, it listens, and your stories become part of your Echo's memory. Over time, your Echo learns how you think, what you value, and what you'd want the people you love to know. You choose exactly who gets access. We call them custodians, usually the people closest to you, like a spouse, a child, or a sibling. Your Echo stays private until a full year of inactivity on your account confirms it's time, and only then does it open up to your custodians. No one gets early access, and nothing happens before it's supposed to. As your Echo grows, premium tiers let you add your real voice with EchoVault Voice or a full avatar with EchoVault Avatar, so the people you love aren't just reading your words. They're hearing and seeing you. Pricing: Echo Seed: free, text-based Echo, up to 3 custodians Echo Voice: $12/month Echo Prime: $18/month One-time video avatar setup: $99.99, includes 3 months of Echo Prime EchoVault won the Inspirational Story award at the World's Largest Hackathon, presented by Bolt. Start building your Echo today. The people who love you deserve more than memories. They deserve you, in your own words and your own voice, for as long as they need you.
