What do you think of Expensive Chat?
Universal-2 by AssemblyAI— Speech-to-Text API for conversational data
SayHenlo is a messaging platform that I built during the #24hrstartup challenge to combat conversation overload. You can only send users 1 message, and can’t send another until they respond to your last one.
Hermes is a decentralized, encrypted chat app, built on Blockstack. Privacy is our priority. Your information is end to end encrypted, and is only shared with the people you choose. You hold your own private keys.
Every time you open up the phone you are going to voluntarily pay 0.003$, not much, but in time it gathers. 50% of the money you are paying will go towards solving an environmental problem, it's a win-win.
Umpyre is a messaging app that helps you get paid for your attention. Sign up, create a badge, post it to your social media profiles so people can contact you. Inbound messages are ranked by their value, so your inbox becomes an auction. Pure value, no spam.
