AssemblyAI— Speech-to-Text API with superhuman accuracy
Currently charting at no.1 in the app store, push it offers a basic follower/following model and lets users send out a push notification to everyone who subscribes to you on the app.
Stream Status is a crazy-powerful notification app that lets you know when your favorite Twitch Streamers are LIVE! Know what, when and for how long they’ve been streaming. Then we’ll even tell you if they change what they’re streaming, are still streaming or if they end their stream so you won’t miss a highlight.
YarpBot is a Twitch Bot that takes a different approach. Instead of using !commands to setup macros to answer questions, YarpBot uses Natural Language Processing to automatically figure out the intent of a user's message and then deliver a customized answer.
