In a normal chat app, you compose a message, then send it - basically really fast letter writing. realtalk. is different. It sends each character you type, as you type it. It all happens in real time, letting you talk over each other and finish each other's sentances, - just like when you're actually talking to someone.
True, it isn't always the most efficient. But it's real conversation, and that's a rare thing for text.
Where we're going, we don't need chat logs. You've got a box showing the last 50 characters you typed, and another showing the last 50 characters your friend typed. The server's got nothing. That's it.
In real time, a conversation moves pretty quickly. So if you want to keep up, you've got to be paying attention. Sometimes, that's not practical. But when you really want to talk to someone, needing to keep the other browser tabs closed is kind of nice.
realtalk. isn't just for desktop. This webapp is built mobile-first and works great on your smartphone, you you can grab the Android app for (planned) notifications. Since you're typing in real-time, autocorrect is disabled, so you've got nobody to blame but Freud when you "mistype" something.
