TLDR: We created a personalised Andrej Karpathy tutor that can response to questions about his Youtube videos in sub 1 second responses (voice-to-voice). We do this using a voice enabled RAG agent. See later in the post for demo link, Github Repo and blog write up. A few weeks ago we released the worlds fastest voice bot, achieving 500ms voice-to-voice response times, including a 200ms delay waiting for a user to stop speaking. After reaching the front page of HN, we thought about how we could take this a step further based on feedback we were getting from the community. Many companies were…

Hey there HN! I believe the future of AI communication will be more voice and less text. Low-latency realistic voice interactions are finally becoming feasible. I've built a few voice-first apps on Retell AI using Elevenlabs voices. This one uses Claude Haiku for responses and Mixtral to switch between posts and comments. The AI knows about the top 30 posts and their comments on Hacker News right now. After a Google sign-in you can try it free for 10 minutes. I'd love to hear your thoughts!

I built a demo of a voice AI task manager. You speak naturally and it updates your visible task list in real time. Try it here, no sign up: https://taskmaster.keithschacht.com I find it useful to talk aloud to figure out priorities. With this, I can just ramble, “Mark that first task as done. Actually undo that. Add a task to proofread it. Move that to the top…” It’s built on LiveKit with a Rails web UI. It listens continuously, maps speech to tool calls, and keeps full task-list state so it understands vague references like “the third item” or “the one with my kids.” Voice feels…

Hey HN, This newsletter didn’t come from a growth hack or content strategy. It started with frustration. Every week, I was drowning in blogs, PR blasts, and Twitter threads trying to keep up with Voice + AI. New models dropping. Partnerships overnight. Startups in India and Asia pushing infra upgrades that no one was covering. But whenever I wanted to know what really mattered, the signal was buried under the noise. And there wasn’t a single newsletter focused on India’s Voice AI ecosystem — most only covered the US. So I built the thing I wished existed: Voice AI Stack — a newsletter on…

I'm a Machine Learning engineer. Struggled with consistency for months on my goals, life etc, so I built something to help myself (zropi.com) but that surprised me or shocked me literally. It’s an AI companion that feels alive: chats like a person. Pauses, emotions, personality. Sends voice notes when it's excited about something or whenever it wants (has its like own mind). Shares photos of itself. But the memory It remembers EVERYTHING. Not just facts context, preferences, random things I mentioned. Last week I asked "how's that thing I told you about going?" and it knew exactly what I…

Most men rehearse hard conversations in their head. Asking someone out, navigating tension, recovering when things get awkward. The rehearsal never works because you're just talking to yourself. I built vibeCoach : a voice AI where you actually practice these conversations out loud, and the AI responds like a real woman would. She starts guarded. One-word answers, a little skeptical. If you escalate too fast or try something cheesy, she gets MORE guarded. If you're genuine and read the moment right, she opens up. Just like real life. Under the hood it's a multi-agent system : multiple AI…
