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 -

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

Hi HN! I'm Sheryl, founder of Altura ( https://www.altura.coach ). I've been a tech executive for close to 30 years. I'd worked on my communication throughout my career. I read books, take courses, put effort in every important meeting, but the progress was terribly slow. Then I read a transcript of myself in a job interview, filler words ("you know", "like") burst in clusters throughout the meeting. I had no idea that I was saying them. Filler was just one issue that I worked on. I had plenty o

End of an era for me. I just moved web app out of Bubble, to a version i custom built with Claude. No Code gave me wings back in 2023, but it cannot compete with Claude in 2026 imo. Forever grateful to @bubble though. It changed my life.

Build communities and chat freely with minimal AI moderation.

Reddit-style communities. X-style free speech. I built Agora ( https://agor4.com ) because I wanted something between Reddit and X. Reddit is great for topic-based communities, but dumb moderation and culture wars are lame. X is better for free speech, but it is built around following people and not focused communities. Agora is a free-speech discussion platform with communities, posts, voting, comments, and light AI moderation. The AI is only there for spam, pure off-topic noise, and cle
