What Happens In Vegas Stays Nowhere on Convos
We launched a secure chat app on XMTP this week with World Chat. We also released our own new chat app on XMTP called Convos this week.
On one hand, I'm like I don't need another chat app. I feel ya. On the other hand, I think we are entering a new era of communication where the apps all work together seamlessly, protect our attention in new ways so I never get spammed, and all come with a level of security that means I'm protected. The best part, is that in this new world, some apps like Convos don't even require me to sign up. No sign up, no account, no phone number, nothing. That's the best part.
When you have Signal level security as an open protocol and foundation with XMTP, it changes how we can use apps together. It opens the door for truly Off The Record Messengers like we are building with Convos. To work perfectly with new Proof of Human chat apps like World. Both protect our attention and communication in ways never possible before.
Check out how I use @convosmessenger as a side chat for @useworldapp when only half our group is going to Vegas next week. This could never have happen in the past with other messengers.
World Chat is my main chat app for real humans. I can protect my inbox with Proof of Human so no AI scams or spam can ever get to me. I want to keep that group forever, and I don’t want to annoy my World Chat group since only half of the them are going to Vegas.
Also, everything that happens in Vegas doesn’t need to last forever. Ya know, all the logistics.
The coolest part about Convos is that I know who’s invited to the group, but I don’t have to share my name inside the group. We all know who’s in the room, but we can’t screenshot and expose who’s in the room. Trust lives offline between people, not the app. The app knows nothing. Like it should be.
I can truly protect my identity and if someone screenshots or records the Convo, it's impossible to prove who said what. It’s a truly safe space to share and chat, a screenshot doesn’t allow someone else to reveal your phone number or identity. You choose how you show up. You choose what you say. No one else can ruin your life with a screenshot. This is what I don’t get from Signal at all. And since there’s no sign-up for Convos, new people can literally pop into a Convo. It's the fastest group chat experience in the world. (Only on iOS right now, download it and try it with your friends, there's not even a sign-up!)
Using apps together for different moments, with different people, that all have Signal level security changes how I think about communication in the future. It’s a whole new world. Group chats are way too hard to start today, and not everything needs to start with a "contact." New relationships don't begin with contact info, they begin with a conversation.
Group chats today are like getting married on a first date. It's a lifetime commitment that I have no idea if I want to be a part of. I should be able to pop in, check it out, and pop out or know it's going to expire. I'd try out a lot more convos, if I knew it wasn't going to last forever.
Sunday night, since I started the Convo, I can explode it. Burns the keys on everyone’s devices, deletes the convo for everyone, and then we go back to World Chat and just pick up where we left off with the whole group.
What happens in Vegas actually stays nowhere.
Convos is the new Off The Record messenger. And it’s perfect to use with any On The Record messenger like Signal, WhatsApp, Telegram, iMessage etc where you have a single phone number and username. Just pop up a Convo and share it in any chat you have in any other On The Record chat app.
Here’s a full screenshare demo I shared on X of how seamless and magical this is. It all just works. Check it out and I'd love feedback.
When you have Signal level security as a foundation, it changes how we can use apps together.
