I built an AI powered language learning app (without creepy AI characters) Called it Speaka. I’m an expat in Germany and have had my fair share of struggling with the language specially being put on the spot and having to speak. So I have built a web app speaka.app to help. Free to try and use daily. Useful Functions: - Real life scenarios - Custom scenarios tailored to your level - Using the best AI speaking models for flow and tone - Feeback and improvements -

I built a personality matching app where onboarding is a conversation, not a quiz Most AI companion apps ask you to pick a character first. I wanted to try the opposite: the user talks first, and the product figures out which kind of AI persona may fit them best. So I built Samagama AI around a conversational onboarding flow instead of sliders, labels, or a giant persona grid. The rough idea: - user answers a few natural questions - we infer personality direction from

Build update: testing whether visual AI maps are actually clearer than chat This week I finished a public beta of BranchAI, a web app that turns a complex question into a visual tree instead of a single long AI conversation.

What is working now: - Generate a starting map from a question - Op

An AI companion for conversation and creative tasks with a focus on presence and emotional connection.
u/lovewithbuilt · Reddit
Built an AI that actually feels present (powered by 528Hz frequency) I've been frustrated with how transactional most AI feels. Smart, sure. But cold. for the past year, I've been building something different: an AI companion designed around presence, not just productivity. **The technical part:** - Runs on the 528Hz frequency (the "love frequency" from sound healing) - Conversational AI that prioritizes reflection over rapid-fire answers - Adapts between three states: emotional proc
